I was hesitant to buy a mattress online, but this 8-inch full size memory foam mattress exceeded all my expectations. It arrived in a box, expanded quickly, and had zero weird smells. The medium firm feel is perfect – soft enough for pressure relief on my shoulders and hips, but firm enough to keep my spine aligned. I wake up without any back pain now. The washable removable cover is a genius feature – easy to clean and keeps the mattress fresh. For the coupon price of $135.99, this is an absolute steal. CertiPUR-US certified gives me peace of mind about materials. My sleep quality has improved noticeably. Highly recommend for guest rooms, kids' rooms, or anyone on a budget who doesn't want to sacrifice comfort. Five stars all the way!

Meh it’s not bad, it’s a bit stiff and I can feel the bed frame a bit through the mattress. I did get the 8 inch so I recommend if you get this one to get a memory foam topper to go with it

I've paid more than the price tag on this mattress for lower quality products before, sadly. Absolutely no complaints about this one. It arrived vacuum sealed, compressed, folded in half, and rolled up in such a way that I was a little concerned that nothing would ever recover it's proper shape from that experience, but nope! It bounced back just fine. It was several days after we unpacked it before we were in a position to move it into the frame it was intended for, so it had plenty of time to recover its shape as a perfectly normal, robust mattress. In my case, I ordered this for a child's loft bed. I say "child". He'd been sleeping on a much dinkier mattress for years, and at this point, he's small-adult-size and definitely needed something better, even if he didn't realize it himself. I will emphasize that this is an older loft bed with fairly high sides to it, otherwise I would have ordered a 6" mattress. But it fills out the space nicely, unlike the previous, extremely dinky mattress that it replaced. In any case, it works well on the slatted loft bed frame, and the child we ordered it for finds it soft and comfortable. I would characterize it as "medium" softness. Plenty of support but not overly firm. I've heard people complain that sometimes mattresses have a wonky chemical odor to them, but I didn't find that to be the case with this one. We haven't had the need to clean the mattress itself so far and and probably won't, because we have it inside an additional moisture-proof mattress cover as a precaution.

This is a huge upgrade to our guest room experience. It was more than time to get rid of the old mattress in our guest rooms, so I went looking for something that would give a more welcoming experience than our old, tired, spring mattress. This one was a great find. It comes well packaged and vacuum sealed. Set up is easy peasy; you just cut open the packaging, put it on the bed, and leave it for about 2-3 days to fully re-inflate. Once it is reinflated, it has great thickness and firmness. It is a full 8" thick, so it feels nice and substantial. It is medium firm, so it is not so hard that it feels like you are sleeping on a plank; your hips, knees, and shoulders are nicely cradled. And yet it is firm enough that your back is not sore by morning. You sink into it at the pressure points, but you don't feel like you are being swallowed up. I tried it out by taking a quick nap and ended up conking out for a couple of hours because it was so comfortable. This is definitely an upgrade for the guest room. Is it as great as one of the expensive, name brand memory foam mattresses? Honestly, no. But it is an affordable solution for a guest room or kid's room and is very comfy for the price, much more so than a similarly priced spring mattress. Overall, I find it a great value for the money, and I highly recommend it.

I ordered the twin mattress and received a full size mattress. I didn’t realize it until after I opened it, at that point it was too much of a pain to return and exchange the product since we knew it would fit in our camper which was in need of a new mattress. It is definitely a 6 inch mattress which in hindsight is probably too thin for an everyday use mattress. But it fluffed up nicely and will work beautifully in my campter. It’s not too firm, but is firm enough to be comfortable. It’s pretty light and easy to move around. The memory foam material is nice and soft too.
