Absolutely LOVE this matress. When it arrived it was well packaged. Upon opening I had doubts it would expand fully. Took it to an open room and cut open vacuum sealed bag. Bed started expanding rapidly. A few hours later and it looked completely expanded but I followed the directions and waited. 72 hours later it was ready. I pressed on the top of the bed and I was worried, it felt stiff almost hard. I then laid on it and my worries went away as it formed around me beautifully. It is firm but very comfortable. The initial smell of plastic was almost completely gone. The first night I we slept on it I did not wake once during the night and awoke feeling really good. I have a bad back and since sleeping on this mattress I have noticed that I awaken with less back pain and stiffness. I am sleeping a lot better also. The gel top on this mattress is amazing as it keeps a nice cool layer even if you stay in the same spot for a long time. When summer comes I see this being a HUGE plus.
Pros: Firm but giving, cooling, even firmness over the entire surface area, smell fades within days
Cons: Honestly none as of yet
I will update in a month or two.
4 month update:
Looks and feels brand new.
No dents, soft/hard spots, and no signs of wear or breakdown.
We live in western Pennsylvania and it has been in the 90s during the day and 68-72 at night. The beds gel layer has been a Godsend.
I go to bed 2-3 hours after my wife and when I sit and then lay down she never knows.
My back has been better in these last 3 months than it has been in years.
1 year update:
Still looks brand new.
No bowing or drooping areas.
Every night the wife and I get in it feels like the first night we slept on it.
This mattress has literally helped me get the best sleep in the last year than I have in 20+ years of having a bad back.
2 year update:
Yes, still in love!
Every night feels like the first night in this dream. Cooling still works fantastic, it is still the same firmness as when brand new, and it stills forms to my body perfectly. Would and will buy again!

I've had a few memory foam beds, most recently a Tuft & Needle mattress from 2018 or so. That mattress was okay, but I always woke up with sore hips from side sleeping, as it was very unforgiving. I also used to wake up often throughout the night in general. I got this one on sale for about a quarter of the price of my last one, and it is helping a lot in both regards. The soft top layer with firmer bottom layer really makes a difference in the side sleeper/hip issue IMO. So far I'm sleeping 100% through the night with no wake ups, just conked out the whole time. That's a good sign to me. There is a factory plastic-like smell but if you've ever owned anything memory foam you'll be familiar with that, and it goes away over time. Pick this up if you want a nice quality bed for a good price.
I still might get another one because they're very affordable, but now I know when it'll need to be replaced.
