We found the mattress to be comfortable, not hot as others mentioned it to be. We were worrisome that the mattress would not hold up well with a heavier weighted sleeper and we found there to be no issues. With a traditional mattress I could feel every movement from my husband and my pets, not with this mattress

I was considering more expensive bed-in-box mattresses (all $1000 plus online), most were hybrids, based on YouTube reviews. I opted instead for this much lower-priced memory foam. For the low price, I thought, well, if it sucks, I won't have invested too much in it. To my surprise, this is a really good mattress. I thought I wanted something really firm because I am larger and had been sleeping on an unsupported, worn out coil mattress. I was worried this would be too soft. It's not. In fact, if anything, it might just be a touch too firm. That said, it is super comfortable. Keep in mind, there will be a little bit of "sink" into the spot you are sleeping in (it is memory foam), so if you move over out of the spot, you might feel the incline a little bit. But, so far, after a couple of weeks, the sunken spot doesn't remain day to day, i.e., it seems to re-firm after getting up for the day. The sink-in does not bother me that much, but I enjoy moving out of that spot, onto a firmer unsunken spot, which is also comfortable. I think it will help also to rotate the mattress fairly regularly. As for heat retention, I had a cotton mattress cover that breathed well, and there was no heat build up. I switched to a higher quality "waterproof" mattress cover, and I noticed more heat retention than before, so I may go back to the cotton one. Its not the mattress but the mattress cover I selected. In short, for the low price I paid on sale, this is a super-comfortable, not too soft, and apparently high quality queen mattress. I have it on a very firm, metal-slatted platform, which works great (no more box springs). Are there more comfortable, more expensive mattresses? Probably, but I don't know. But spending more than $400 or $500 on a mattress seems insane to me. For the price and comfort, I am very pleased with this one (and I am often very difficult to please with these types of things).

So far has been a great mattress. It is firm but soft, almost a perfect balance. I thought it was going to be too firm when I first started sleeping on it but I was worrying for no reason because I have had the best sleep I have had in years and no longer wake up with a backache. Comes in a box and is very easy to open and get set up. It did smell a little chemically, but has since went away. We use this with an adjustable frame and they work great together.

This is the second time I've purchased this mattress over the years, and I'll probably buy a third. It's incredibly comfortable – just firm enough, but not too firm, and it's great for people who are side sleepers. I got one several years ago for my queen-sized bed, and I just bought a king-size for my son and his wife for their new home. I'll most likely replace my current king-size mattress with this one in the near future because it's the most comfortable mattress I've ever slept on! Highly recommend!

I love this mattress! The best mattress i have ever slept on. Its soft enough that it molds to ur body, but firm enough to keep u from tossing and turning. My complaint on this mattress is my blankets slip off the mattress really easy. It is really hard to turn onto ur side while laying down.

The Serta SleepToGo 12" Gel Memory Foam Luxury Mattress is wonderful. I loved the fact that we didn't need a big truck to haul it in since it came rolled in a box. It was packaged very well by the manufacturer. The mattress is so comfortable. On our old mattress, I would wake up whenever my husband turned over in bed. I no longer have this problem. I am sleeping so much better now. I also love the fact that I don't get too warm while sleeping on this mattress. I would buy this mattress again!

I was surprised what a small box it came in and thought that surely after it expanded into full size that it must have to be too mushy in order to do that. I was wrong. It feels great! When you touch it, it feels firm, but when you lay on it your body presses into it just enough...Glad I got rid of my old Select Comfort bed

I was looking for a medium firm mattress. I am heavy so I need support. It was what I needed and was the only option available for pick up. I feel it was a little too expensive for the quality but I didn’t wake up with a backache so, overall, it’s good.

Its a nice luxury firm mattress, exactly what I was looking for. The gel memory foam top layer contours your body shape very well. At first it may seem too firm, however you slowly start sinking into it after a few hours of sleep. By the morning, you would have sunk almost an inch or two into the mattress and the support for the back is not the best. I find myself tossing and turning in bed the last 2 hours of my sleep. For the price, it deserves a rating of 4, but I am still looking for the perfect mattress.

My oldest son bought the 10” and I was happy and satisfied with the one HE bought. So I decided to upgrade my youngest what I thought would be even better, the 12” mattress but the ends took almost 48hrs to fully expand and all the ends go all the way down when u sit down. Not at all what we expected. We will be replacing this one sooner then we thought!
