This isn't the medium-firm mattress that I was hoping for, but it still is a decent mattress. I'd consider it firm with a slight (very slight) "give". The give isn't enough to drop it down anywhere into the medium range, but it's enough to provide decent support to back sleepers. I wouldn't recommend for side sleeper--unless that person is thin with narrow frame/shoulders and/or loves a firm mattress. Even heavier family members don't get much sink. Sometimes mattresses like this will bottom-out. This one is just firm. The sides do not have too much support so if you're a sleeper who prefers a big more sinking feeling you may find yourself sleeping on the edges. Just be careful that you don't roll onto the floor! We didn't notice any off-gassing (which is both good because it's ready-to-go but also bad because it's rather suspect given the materials). Overall, this is a gem of a mattress given the price if you're seeking a firm memory foam. I'd probably consider more for a guest room or child's room. I purchased it for a main bedroom mattress but it got moved to the spare room which we use when we just want to stretch out or take a quick nap. This mattress has more of a "sleep on top" rather than cradle/sink-in feel so it just depends on your preference. I haven't had it long enough to see if it gets much softer over time. A steal for the price. But still not right for my nightly comfort preference. (I wonder if quality control is an issue if people are actually getting/experiencing a softer sleeping experience). Overall, an okay mattress. Great for the price.

The mattress was not comfortable. It felt like sleeping on a bunch of pillows stuffed inside a casing. Lumpy and no support. I love Sam's but had to return this. The only requirement for the return to store was to wrap in plastic. Easy return no questions or hassle.

Mattress is very comfortable - softer top with firm support. A high quality mattress that doesn't break the bank. It was easy transport since it comes in a box. Be sure to have the box spring/platform bed ready for the mattress because once you unravel and cut open the plastic it is heavy and harder to move around then when in a box :)

This mattress is soooo comfortable, and sturdy to! We are using it for a kids loft bed, no box spring is needed, and it fit perfectly for the size of the frame. Tip: place mattress on base BEFORE you cut the plastic cover, it fills with air to size very quickly.

This bed is amazing! I was skeptical of a bed in the box but the price point was really good so I got it for the guest bedroom. I tried it out and after two night I swapped it out with my traditional mattress in my room. Way more. Comfortable and forgiving than the traditional mattress with a foam cover!

We purchased this mattress for our guest room. My in laws stayed with us and like the mattress so much they bought one for themselves when they got home. They said they didn't have any pains the week they were with us and noticed a difference immediately when they got home.

I took a chance by reading all the great reviews. Well that chance was a gamble I lost. Where do I start. First I let it air out for 72 hrs 24 more hrs than recommended and it still never fully inflated. Second this mattress is totally uncomfortable. I’ve slept on cots while deployed that was more comfortable. This was $400 plus bucks down the drain that I couldn’t afford. You live and you learn.

When laying anywhere in the center of the bed it feels great. Not too firm, not too soft but dont try sitting on the edge or especially the corners of the bed, you will sink down and eventually slide off the bed. This would be somthing that I could overlook but I bought it for when my grandmas visit and they like to sit on the edge of the bed. This would not be safe for them. On top of that, the store wouldnt let me exchange it because i had discaeded the box it came rilled up in. It's not like you can put it vack in there! I had proof of purchase. So now, im stuck with it.

This is my first mail order mattress, so I was a bit skeptical.Mattress arrived quickly and I was able to get it set up by myself. It immediately took shape once plastic was removed. After just a few hours it was ready to sleep on. It is a quiet mattress and I would consider it plush to firm. It almost feels like the mattress absorbs you, very little bounce when moving on it. The sides are not firm when you sit on them, but that has no effect on the sleep quality I've gotten and that's not an issue for me at all. If you must have super firm and supportive bed edges, it may be an issue. I have less back and neck pain since sleeping on this mattress and wish I'd bought one sooner. I feel like it is a good value for the price and I very pleased with it. I hope it holds up well.

Totally as advertised. It is a firm mattress. Motion transfer is minimal on a platform bed. We did end up using a plush mattress cover to soften the top just a little. Very happy with the purchase and the price. Delivery was quick. Follow directions on opening as it recovers shrink wrapped very quickly. We let it expand about 7 hours. Slept great the first night and every night since!
