It arrived in a small box, no idea that they would vacuum seal a mattress! That's what they did, seemed to work. Opened it up and poof it inflated to normal. It's good enough for our kid!

I love this foam mattress. It's firm but soft and conforms with your body.So relaxing lying on it.About the price, it's cheap that's why the best deal ever for me at Sams.

Absolutely comfortable. It's actually like sleeping on a cloud. No bounce so you won't disturb your spouse when you get in and out of bed. Just perfect.

Bought this mattress for our RV. It's not quite as good as our more expensive bed at home but it is certainly everything we hoped for. Great buy at a very good price!

Super comfortable!

Very nice

No smell. No fuss.

This mattress is very firm, but not hard. The memory foam has just enough give to make this mattress feel comfortable but your spine alignment will remain straight. I have a bad back and hips. This bed supports my back but has just enough give that I can lie on my side without my hips hurting. I did not notice any weird odors, but I do have a dust mite cover on it. It was fun to watch it expand when I unpacked it. If I need another mattress, I will not hesitate to repurchase.

Bought this for my 4 year old after reading great reviews! This mattress is very comfortable! My son sleeps mostly through the night now, which he did not do in his toddler bed! The only con is that the edges are not reinforced with anything, so you can't sit on the side easily, but that's not really a huge deal. Oh, and my husband built slats because we had a regular bed frame and this mattress needs either the special bed frame made by the same brand or something to reinforce the bottom (box spring, slats, etc.)

The twin size mattress arrived promptly in a large box. It is made in China. The shipment was lighter and the box considerably smaller than if the mattress had been an inner spring with steel coils and frame. The mattress was partially compressed in a tight roll in a sealed poly vacuum bag with much of the air removed from the foam. Then the roll was further packed in a sturdy cylindrical white plastic outer bag with a draw cord tie, before being slid into the box for shipment. Unpacking was the reverse, following the step-by-step picture instructions. As soon as the mattress was rolled out flat and the inner poly bag was opened, air began to rush in and fill the foam, expanding the mattress. I ordered the 8" thickness and the fully expanded mattress was almost 8 1/2" thick. This took about 48 hours, per the instructions. The result was a medium-to-firm mattress with the top layer of "memory" foam conforming to the body. After unpacking, there was an odor from the foam that I would describe as like latex-based paint. Although people vary in their reactions to odors, I would judge the odor to be rather mild, certainly not as intense as painting a bedroom with latex. Allowing the mattress to air for the prescribed 48-72 hours dissipated the odor to the point that I found it unnoticeable. One thing I didn't see in the description on the Sam's Club website (perhaps I missed it): The Night Therapy Memory Foam Mattress is not intended to be used with a foundation, such as a box spring. It is intended for a platform or bunk bed. I am using it on a captain's bunk with a continuous firm plywood surface, which works. Also, the mattress cannot be turned over with each sheet change to even out stress. The top is the top, the bottom is the bottom. The mattress can be rotated with each sheet change, head to foot. All in all, a nice quality-made foam mattress reasonably priced that gives a comfortable night's sleep. I would have given it 5 stars, but would like to see how it performs over time. So far only one night on the new mattress.
