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).

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 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 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.

It's a little too firm for side sleeping, as it makes my hips and lower back hurt if I sleep on my side too long. It's fine for back or stomach sleeping. One side of the bed is already more worn in than the other side after only a month, and I feel like a memory foam mattress shouldn't be uneven like this.

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!

Very good so far, my thickness is only 12 inches after 2 weeks but don’t think it would change comfort much. Will note it is a little warmer than conventional mattress. Too early to recommend.

this mattress is firm and very comfortable , cooler than other memory foam we have . using this mattress in a 2021 rv in place of original mattress . amazing upgrade .

Bought 2 mattress for both of my guest rooms. The first guests on each bed said it was really comfortable and they slept great. I feel well worth the money.

Sadly this mattress turned out to be less comfortable then the Serra mattress I was hoping to replace. Back aches returned, and very soft edges, not happy with the purchase.
