Definitions
- the present invention relates to mattresses, in particular a mattress with a cover.
- a plastic lining or protector is usually positioned over a sleeping surface of the mattress, beneath any bed linen. This configuration is both uncomfortable and inconvenient as the plastic protector tends to shift under the pressure of a person's body weight.
- Such a configuration is of an even greater disadvantage in the care of infants, bed-ridden or elderly people, as upon soiling of the bed linen and mattress, the person/infant has to be lifted, the soiled linen removed and fresh linen replaced on the bed.
- Such a task is time consuming and laborious, and often proves to be highly inconvenient not only for the bed-ridden person/infant, but also for the carer such as, for example, a parent or nurse.
- the present invention provides a mattress with a cover, said mattress having a first sleeping surface and a second sleeping surface and said cover comprising a first removable portion for covering the first sleeping surface, a second removable portion for covering the second sleeping surface and a third portion positioned around the lateral periphery of the mattress for removably attaching said first and second removable portions of the mattress cover to the mattress.
- the third portion is sewn onto the mattress.
- the third portion may be fixed to the mattress by means of studs, hooks, adhesive or by any other means capable of fixing the third portion to the mattress.
- the third portion comprises one half of a first closure member that is fixable to the complementary half of the first closure member attached to the first removable portion of the mattress cover and further comprises one half of a second closure member that is fixable to the complementary half of the second closure member attached to the second removable portion of the mattress cover.
- the first and second closure members are zips.
- the third portion extends continuously around the periphery of the mattress.
- the first removable portion and the second removable portion are interchangeable so that the first removable portion is attachable to the mattress for covering the second sleeping surface and the second removable portion is attachable to the mattress for covering the first sleeping surface.

- the first closure member attached to the first removable portion is positioned at a distance from the edge of the first sleeping surface and the second closure member attached to the second removable portion is positioned at a distance from the edge of the second sleeping surface.
- the mattress is weighted, such positioning of the closure members on the mattress reduces the force that is directly applied to the region at which the first removable portion and second removable portion of the cover are attached to the mattress. This therefore allows the mattress with cover to withstand higher loads.
- the third portion is manufactured from a permeable material. This allows the mattress to “breathe” (i.e., allows the expulsion of dust and dust mites which are not able to filter through the first and second sleeping surfaces of the mattress that are lined with an impermeable material). Most preferably, the third portion comprises at least one ventilation port. Such a ventilation port also aids in the expulsion of dust and dust mites laterally of the mattress.
- said first and second sleeping surfaces of the mattress are made from an impermeable material.
- the first and second surfaces of the mattress may be lined with an impermeable material or alternatively, the first removable portion and the second removable portion of the cover may be lined with an impermeable material.
- the arrangement wherein the first and second removable portions of the cover are lined with an impermeable material would be particularly advantageous from an aesthetic perspective, since the mattress itself need not be lined with an impermeable lining, but rather, may be covered in fabric such as, for example, cotton, which looks and feels more attractive in comparison to an impermeable plastic lining. In such embodiments the mattress may be functional and comfortable with or without the removable covers.
- the impermeable material is waterproof to prevent soilage of the underlying mattress.
- the impermeable material is waterproof and is impermeable to dust and dust mites.

- the third portion 7 surrounds the lateral periphery of the mattress and is sewn to the mattress.
- the first and second removable portions 3 , 5 of the cover may be removed to expose a mattress having a first sleeping surface ( 9 ) and a second sleeping surface opposite the first sleeping surface 9 (not shown).
- both of the first and second removable portions 3 , 5 of the cover are made out of cotton, which is breathable, absorbent and washable. However, materials such as linen and polyester fleece may also be used for the first and second portions 3 , 5 of the removable cover.
- the first sleeping surface 9 and second sleeping surface are made from an impermeable material so as to protect the mattress from soiling and also, to prevent dust mites and dust from filtering through the mattress onto the face of a sleeping infant/person.
- the first and second removable portions 3 , 5 of the cover may be lined with an impermeable material. In the present embodiment, the impermeable material is plastic, however materials such as vinyl or cotton may alternatively be used.
- the present invention allows the first removable portion 3 to be readily detached from the mattress by unzipping the zip 4 that attaches the first removable portion 3 of the cover to the mattress. Hence, should removable cover 3 be soiled, it can be quickly removed. Further, the whole mattress can then be turned over, and the second removable portion 5 of the cover is ready for immediate use. The second removable portion 5 may also be removed by unzipping zip 6 .
- Such a configuration precludes the need for the use of a separate plastic protector over the mattress and beneath bed linen.
- Such a configuration also precludes the need for the use of bed linen as the first and second removable portions 3 , 5 of the cover are made of a comfortable material, cotton, and may be readily and conveniently removed and washed as required.
- the third portion 7 is of a width w that is less than the thickness T of the mattress.
- zip 4 is positioned at a distance from the edge 8 of the first sleeping surface 9 and zip 6 is positioned at a distance from the edge 10 of the second sleeping surface.
- Such positioning of the zips 4 , 6 on the mattress reduces the force that is directly applied to the zips when the mattress is loaded. As zips are often the point of failure during heavy loading, this arrangement may allow the mattress with cover 1 to withstand higher loads.
- the third portion 7 is made of a breathable material which allows any dust mites and dust to be expelled laterally through the sides of the mattress.
- the impermeable lining on the first and second sleeping surfaces of the mattress prevents the filter of dust and dust mites through the first and second sleeping surfaces. This therefore avoids dust mites and dust from being expelled directly onto the face of a sleeping person or infant.
- the third portion 7 comprises a plurality of ventilation ports 13 so as to further aid in the filter of dust mites and dust laterally from the mattress in a direction away from the face of a sleeping person/infant.
- Such a system is hygienic and provides great benefit to, in particular, infants, elderly persons and/or persons with respiratory problems.
- the first removable portion 3 and the second removable portion 5 are interchangeable on mattress 1 . That is, the first removable portion 3 may be attached to the third portion 7 by means of zip 4 so as to fit over the first sleeping surface 9 , or may be attached to zip 6 so as to fit over the second sleeping surface 11 of the mattress 1 .
- the second removable portion 5 may be attached to the third portion 7 by means of a zip 6 , so as to fit over the second sleeping surface 11 of the mattress 1 , or may be attached to zip 4 so as to fit over the first sleeping surface 9 .
- Such an arrangement wherein the first and second removable portions 3 , 5 are interchangeable between the first or second sleeping surfaces 9 , 11 of the mattress 1 , requires sliders 25 , 27 of the first and second zips 4 , 6 to travel in opposite directions around the periphery of the mattress 1 in relation to each other when being opened.
- This enables the slider 25 located on the first zip 4 and the slider 27 located on the second zip 6 to be locked to one another so as to prevent the sliders from being unzipped in the opposite directions thereby preventing the removal of the first and second removable portions 3 , 5 of the mattress cover from the mattress 1 .
- a small padlock may be used to lock the sliders together.
- one or both of the slides 25 , 27 may be locked to the mattress to prevent removal of the removable portions 3 , 5 .
- Such an arrangement may be particularly advantageous when used in hotels, to assist in the prevention of theft of bed linen and the like.
- first and second removable mattress covers 3 , 5 of the present invention may be manufactured to particular sizes or with the zips 4 , 6 in a particular, unique, position, so as to fit specially manufactured mattresses having a complementary yet non-conventional size to a standard mattress.
- This system may be advantageous in preventing or at least minimising the incidence of theft of the removable covers from, for example, hotels due to their non-compatibility with standard mattresses.
- the mattress with removable cover of the present invention is formed by carrying out the following steps.
- the mattress side border is the portion of the mattress which extends around the lateral periphery of the mattress, as indicated by 20 in FIG. 4 .
- the mattress side border 20 must extend over the full thickness of the mattress, and must comprise two female zip portions 24 and 26 , each extending around the periphery of the mattress 1 .
- Zip portion 24 must be positioned a substantially constant distance from the edge 8 of the sleeping surface 9 of the mattress all the way around the mattress, and zip portion 26 must be positioned a substantially constant distance from the edge 10 of the other sleeping surface of the mattress, all the way around the mattress.
- Each of female zip portions 24 , 26 have a female slider 25 , 27 for closing the zips when a male zip portion is in place.
- female zip portions 24 , 26 respectively form a part of zips 4 , 6 .
- the sliders 25 , 27 are shown at the starting position of each of zips 4 , 6 , which has been chosen to be at the centre of an end of the mattress for aesthetic purposes.
- female zip portions 24 , 26 must be accurately positioned on the mattress side border 20 , in a manner which is repeatable from one mattress to the next. This is achieved by use of template C shown in FIG. 5 c , as follows.
- the two female zip portions are each sewn to respective fabric strips 21 , 22 , which are to form the outer portions of mattress side border 20 .
- the female zips 24 , 26 and fabric strips 21 , 22 must simply be long enough to extend around the entire circumference of the mattress.
- a fabric strip, to act as third portion 7 of the mattress side border 20 is placed between the two female zips 24 , 26 along the length of template C, and placed under slight tension.
- the fabric strip 7 is then stapled or pinned to the female zip portions 24 , 26 .
- the proper length of the mattress side border is marked on one or more of the elements in place on template C, using the indicators 56 , 57 on template C.
- the indicators 56 , 57 have been positioned such that the mattress side border 20 will accurately fit around the lateral periphery of the mattress.
- template A is used, shown in FIG. 5 a.
- Mattress side border 20 is placed around the lateral periphery of a mattress inner, for example a steel spring mattress blank.
- the mattress blank has insulation positioned over the sleeping surfaces defined by the steel springs, and has foam substantially surrounding the springs and insulation.
- the mattress side border 20 will fit snugly around the lateral periphery of the mattress blank, as the fabric strip 7 was placed under slight tension during formation of mattress side border 20 .

Abstract
A mattress with a cover (1), said mattress having a first sleeping surface (9) and a second sleeping surface and said cover comprising a first removable portion (3) for covering the first sleeping surface, a second removable portion (5) for covering the second sleeping surface and a third portion (7) positioned around the lateral periphery of the mattress for removably attaching said first and second removable portions of the mattress cover to the mattress.
Description
- The present invention relates to mattresses, in particular a mattress with a cover.
- In order to protect conventional mattresses from soiling, a plastic lining or protector is usually positioned over a sleeping surface of the mattress, beneath any bed linen. This configuration is both uncomfortable and inconvenient as the plastic protector tends to shift under the pressure of a person's body weight.
- Such a configuration is of an even greater disadvantage in the care of infants, bed-ridden or elderly people, as upon soiling of the bed linen and mattress, the person/infant has to be lifted, the soiled linen removed and fresh linen replaced on the bed. Such a task is time consuming and laborious, and often proves to be highly inconvenient not only for the bed-ridden person/infant, but also for the carer such as, for example, a parent or nurse.
- Additionally, where no plastic protector is used, dust and dust mites tend to filter through the mattress (usually made out of some breathable material such as cotton) directly onto the face of the sleeping person/infant. This is particularly problematic for elderly people, infants, and people with respiratory problems such as asthmatics.
- Any discussion of documents, acts, materials, devices, articles or the like which has been included in the present specification is solely for the purpose of providing a context for the present invention. It is not to be taken as an admission that any or all of these matters form part of the prior art base or were common general knowledge in the field relevant to the present invention as it existed in Australia before the priority date of each claim of this application.
- In a first aspect, the present invention provides a mattress with a cover, said mattress having a first sleeping surface and a second sleeping surface and said cover comprising a first removable portion for covering the first sleeping surface, a second removable portion for covering the second sleeping surface and a third portion positioned around the lateral periphery of the mattress for removably attaching said first and second removable portions of the mattress cover to the mattress.
- Preferably, the third portion is sewn onto the mattress. However, the third portion may be fixed to the mattress by means of studs, hooks, adhesive or by any other means capable of fixing the third portion to the mattress.
- Preferably, the third portion comprises one half of a first closure member that is fixable to the complementary half of the first closure member attached to the first removable portion of the mattress cover and further comprises one half of a second closure member that is fixable to the complementary half of the second closure member attached to the second removable portion of the mattress cover. Most preferably, the first and second closure members are zips. Preferably, the third portion extends continuously around the periphery of the mattress.
- Preferably also, the first removable portion and the second removable portion are interchangeable so that the first removable portion is attachable to the mattress for covering the second sleeping surface and the second removable portion is attachable to the mattress for covering the first sleeping surface.
- Preferably, the third portion is of a width that is less than a thickness of the mattress. As such, the first closure member attached to the first removable portion is positioned at a distance from the edge of the first sleeping surface and the second closure member attached to the second removable portion is positioned at a distance from the edge of the second sleeping surface.

FIG. 8 depicts the mattress with removable cover in accordance withFIG. 6 in which the sleeping surface portion is in a partially open position so as to expose the underlying surface of the base portion. - FIGS. 1 to 4 depict a mattress with
cover 1 in accordance with a first preferred embodiment of the present invention which comprises a firstremovable portion 3, a secondremovable portion 5 and athird portion 7, wherein both of the first and secondremovable portions third portion 7. As is depicted in FIGS. 1 to 4, thethird portion 7 surrounds the lateral periphery of the mattress and is sewn to the mattress. The first and secondremovable portions - In the embodiment shown, both of the first and second
removable portions second portions removable portions - The present invention allows the first
removable portion 3 to be readily detached from the mattress by unzipping thezip 4 that attaches the firstremovable portion 3 of the cover to the mattress. Hence, shouldremovable cover 3 be soiled, it can be quickly removed. Further, the whole mattress can then be turned over, and the secondremovable portion 5 of the cover is ready for immediate use. The secondremovable portion 5 may also be removed by unzippingzip 6. Such a configuration precludes the need for the use of a separate plastic protector over the mattress and beneath bed linen. Such a configuration also precludes the need for the use of bed linen as the first and secondremovable portions - In the embodiment shown in FIGS. 1 to 4, the
third portion 7 is of a width w that is less than the thickness T of the mattress. As such,zip 4 is positioned at a distance from theedge 8 of the first sleeping surface 9 andzip 6 is positioned at a distance from theedge 10 of the second sleeping surface. Such positioning of thezips cover 1 to withstand higher loads. - In the embodiment shown in FIGS. 1 to 4, the
third portion 7 is made of a breathable material which allows any dust mites and dust to be expelled laterally through the sides of the mattress. As previously mentioned, the impermeable lining on the first and second sleeping surfaces of the mattress prevents the filter of dust and dust mites through the first and second sleeping surfaces. This therefore avoids dust mites and dust from being expelled directly onto the face of a sleeping person or infant. Further, thethird portion 7 comprises a plurality ofventilation ports 13 so as to further aid in the filter of dust mites and dust laterally from the mattress in a direction away from the face of a sleeping person/infant. Such a system is hygienic and provides great benefit to, in particular, infants, elderly persons and/or persons with respiratory problems. - In the embodiment shown, the first

That is, the firstremovable portion 3 may be attached to thethird portion 7 by means ofzip 4 so as to fit over the first sleeping surface 9, or may be attached tozip 6 so as to fit over the second sleeping surface 11 of themattress 1. Similarly, the secondremovable portion 5 may be attached to thethird portion 7 by means of azip 6, so as to fit over the second sleeping surface 11 of themattress 1, or may be attached tozip 4 so as to fit over the first sleeping surface 9. Such an arrangement, wherein the first and secondremovable portions mattress 1, requiressliders second zips mattress 1 in relation to each other when being opened. This enables theslider 25 located on thefirst zip 4 and theslider 27 located on thesecond zip 6 to be locked to one another so as to prevent the sliders from being unzipped in the opposite directions thereby preventing the removal of the first and secondremovable portions mattress 1. A small padlock may be used to lock the sliders together. Alternatively, one or both of theslides removable portions - It is also envisioned that the first and second removable mattress covers 3, 5 of the present invention may be manufactured to particular sizes or with the
zips - In the present embodiment, the mattress with removable cover of the present invention is formed by carrying out the following steps.
- 1) Construct
Mattress Side Border 20. - The mattress side border is the portion of the mattress which extends around the lateral periphery of the mattress, as indicated by 20 in
FIG. 4 . In the present embodiment, themattress side border 20 must extend over the full thickness of the mattress, and must comprise twofemale zip portions mattress 1.Zip portion 24 must be positioned a substantially constant distance from theedge 8 of the sleeping surface 9 of the mattress all the way around the mattress, andzip portion 26 must be positioned a substantially constant distance from theedge 10 of the other sleeping surface of the mattress, all the way around the mattress. Each offemale zip portions female slider female zip portions zips FIG. 4 , thesliders zips - To enable interchangeability of a cover from one side of the mattress to the other, and from one mattress to the next,
female zip portions mattress side border 20, in a manner which is repeatable from one mattress to the next. This is achieved by use of template C shown inFIG. 5 c, as follows. - 1a) The two female zip portions are each sewn to respective fabric strips 21, 22, which are to form the outer portions of
mattress side border 20. At this stage, the female zips 24, 26 and fabric strips 21, 22 must simply be long enough to extend around the entire circumference of the mattress. - 1b) The two
female zip portions FIG. 5 c) corresponds to the length of the circumference of the lateral periphery of the mattress. Template C has first and secondmale zip portions orifice 53 through templateC. Starting points male zip portions FIGS. 1, 2 ). The starting points of thefemale zip portions - 1c) A fabric strip, to act as
third portion 7 of themattress side border 20, is placed between the twofemale zips fabric strip 7 is then stapled or pinned to thefemale zip portions female zip portions - 1d) The proper length of the mattress side border is marked on one or more of the elements in place on template C, using the
indicators 56, 57 on template C. Theindicators 56, 57 have been positioned such that themattress side border 20 will accurately fit around the lateral periphery of the mattress. - 1e) The combination of the
strips female zip portions fabric strip 7, is then removed from template C by opening the zips.Female zip portions fabric strip 7 along the full length of thefabric strip 7. - 1f) The combination is then pulled into a loop and sewn where marked such that the loop is of the same circumference as the mattress, completing the
mattress side border 20. It is to be noted that, due to the placement of thestarting points zip portions zips mattress 1. - 2) Forming
Mattress 1, Without Covers - To form the
mattress 1 such that thefemale zip portions FIG. 5 a. - 2a)
Mattress side border 20 is placed around the lateral periphery of a mattress inner, for example a steel spring mattress blank. The mattress blank has insulation positioned over the sleeping surfaces defined by the steel springs, and has foam substantially surrounding the springs and insulation. Themattress side border 20 will fit snugly around the lateral periphery of the mattress blank, as thefabric strip 7 was placed under slight tension during formation ofmattress side border 20. - 2b) The mattress blank and
mattress side border 20 are then placed into template A. Thelength 1 A and width WA of template B are such that the mattress fits closely into recess 61, and thatmale zip portion 60 of template A is positioned to connect to a female zip portion of the inserted mattress. The depth dA of the recess 61 corresponds to the width of each ofstrips mattress side border 20. Thestarting point 62 ofmale zip portion 60 is positioned at the centre of one end of template A.Female zip portion 26 is attached to themale zip portion 60 of template A and the zip thus formed is closed around the entire lateral periphery of the mattress blank.Female zip portion 24 is then held above the rim of template A by about the thickness offabric strip 7. - 2c) A sheet of impermeable fabric, to serve as sleeping surface 9, is placed over the exposed sleeping surface of the mattress blank. The sheet of fabric 9 is then securely sewn to
fabric strip 21 of themattress side border 20, all the way around theedge 8 of the sleeping surface 9, while both the sheet of fabric 9 andmattress side border 20 are under slight tension againstmale zip portion 60. - 2d) The mattress blank is removed from template A, turned over, and placed back into template A. The same template may be used for positioning both zips, due to the interchangeability of covers on the mattress.
- 2e)
Female zip portion 24 is attached to themale zip portion 60 of template A, and the zip thus formed is closed around the entire periphery of the mattress, positioningfemale zip portion 26 above the rim of template A by the thickness offabric strip 7. - 2f) A second sheet of impermeable fabric, to serve as the second sleeping surface of the
mattress 1, is place over the mattress blank, and sewn to thefabric strip 22 of themattress side border 20 all the way around theedge 10 of the second sleeping surface, while both the second sheet of impermeable fabric and themattress side border 20 are held under slight tension against template A. This completes formation of themattress 1 without covers, with thefemale zip portions mattress 1 due to use oftemplate A. Mattress 1 can then be removed from template A by unzippingfemale zip portion 24 from themale zip portion 60 of template A. - 3) Forming a Removable Cover
-
Removable covers covers mattress 1, and may also be interchanged with covers on other such mattresses. To form such a cover, template B is used, as described below with reference to formation ofcover 3 shown in FIGS. 1 to 3. Although the method of the present embodiment will be described with reference to a mattress having two removable covers, one over each sleeping surface, it is envisioned that the method may be applied to form a mattress having a removable cover over only one sleeping surface. - 3a) A strip of fabric, to serve as
lateral portion 18 ofcover 3, is sewn to a male zip portion 19 (seeFIG. 3 ). At this stage, the male zip portion andfabric 18 simply need to be long enough to pass around the entire lateral periphery of the mattress. - 3b) The
male zip portion 19 is attached tofemale zip portion 70 of template B, and the zip thus formed is closed by slidingslider portion 71, shown at a starting position ofzip 70, all the way around template B. Themale zip portion 19 andfabric 18 are marked to the correctlength using indicator 72. - 3c) The
male zip portion 19 is then removed from template B, and thefabric strip 18 and themale zip 19 are formed into a loop and sewn at the marking, such that the loop fits snugly around the mattress. - 3c) The sewn loop is then zipped to the template using
female zip portion 70. The distance dB of template B corresponds to the width offabric strip 18. - 3d) A cover sleeping portion is then placed over template B, which has a
length 1 B and a width wB substantially equal to the sleeping surfaces of themattress 1. The cover sleeping portion is then sewn to thefabric strip 18 all the way around theedge 8 of the sleeping surface. Thecover 3 is then complete and can be unzipped from template B. The working surface of template B is covered with a layer of foam so as to protect the needle of a sewing machine that is used to sew the cover sleeping portion to thefabric strip 18. Such a foam layer also protects the cover placed or formed over the working surface of template B from tearing. - As will be appreciated, the use of three templates in the previously described manner assists in achieving accurate workmanship, and assists in repeated construction of interchangeable mattresses and mattress covers. Each of the three templates provides a rigid support structure which allows for accurate measurement, marking, alignment and mounting of a zip to a mattress cover or mattress. Such templates ensure that zips are consistently placed in the same position on each mattress and mattress cover formed by using the templates, resulting in removable covers that can be interchanged between different mattresses and between different sides of the same mattress. In the embodiment described, the male part of a zip is attached to each of the first and second removable portions of the cover while the female part of a zip is fixedly attached to the mattress. This ensures that the zip with a slidable closure member is not attached to the first or second removable portions of the cover, and therefore is not removed with either of the first or second removable portions. One advantage of this arrangement is that washing of a cover comprising a slidable closure member in a washing machine could potentially cause damage to both the slidable closure member and the washing machine.
