Amazon Basics Memory Foam Mattress, Medium Firm, Cooling Gel, Queen Size Mattress, CertiPUR-US® Certified Foam, 80 x 60 x 10 inches, White/Gray

Night one: I opened it up yesterday morning from the packaging, let it breath for 30 hours, and now it's sitting on my boxspring. It was easy enough to move around as a single adult male, but would be easier with two people. The mattress itself is comfortably firm, it has a small amount of give in it so you do sink in a little bit, but it's firm across my whole body. I suspect this will be great for at least 3-4 years, and at the price tag delivered to my door, that's a very appealing repurchase.

This mattress wasn't my first choice, but it came up as "try this instead" when my first choice wasn't available. We decided to give it a try, as our previous mattress was an unknown, but large, number of years old.Hubby broke his back a few years ago in a motorcycle accident. I've sprained my back twice and seriously injured my shoulder twice (no fun as a side-sleeper). Support as well as 'give' is of paramount importance. Its hotter than blazes in Texas, too, so something that helps keep us cool is money well spent. I guess I don't know for sure how well that works but hubby has not complained about being hot, and I still sleep under the sheet and blanket.Its soft and firm at the same time. Its truly a pleasure to use. We watch TV mostly in our room from bed, so it gets much more use than just sleep. Hubby and I don't feel each other move around. There was no period of "getting used to" the mattress. It was comfortable from day one. It is 10" tall so I do need to buy deeper-pocket sheets and our current short-term solution is to use those sheet clip things.It arrived on time, and poofed up exactly like it was supposed to. We laid it out in the morning and slept on it that night.For the price I honestly don't have high expectations for longevity, and I'll be happy if it lasts a few years.... Lord knows I do hope to be pleasantly surprised. However, under the assumption that this is most likely short term, it's MORE than worth it to us and we're VERY happy with it so far!

My stats: 6'1" 200lbs pinched spinal column, sciatic nerve impingement, poor sleeper, hot sleeperAbsolutely 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 daysCons: Honestly none as of yetI 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 ended up putting a thin memory foam on top but that is just me, I wanted it softer but after 3 weeks it has worked well for me

good luck cutting open the super tight plastic without damaging it.
