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.

Bought one for my 20 year old college student. He says its very comfortable. I would buy the 12" if I had to do it again, only because the sheets are somewhat loose on the 8" mattress. His old standard pillow top mattress was about 1 1/2" thicker. Overall a very good buy for the money.

After reading all the positive reviews we decided to buy 2 for a bunk bed set. Our 2.5 year old has been sleeping on one for the last couple weeks and he loves it. Prior to sleeping on this mattress he was up at least once a night and now he sleep right through the night. I read some comments about the smell when the mattress gets unpackaged but I didn't think it was an issue at all. Very good quality and value that is tough to beat--I wish they were available in store and not just on line.

Love this mattress. It came on time and was well packed. I ordered the twin. It was light and easy for me to carry up two flights of stairs by myself. When I opened it, it started to expand right away. It was to the full eight inches within an hour. I love the fact that there was no odor at all and it is the perfect cross between soft and firm. I would highly recommend this matress.

After comparison shopping for a bed for a bad back, we found a suggestion for this brand. We ordered a 13" king and decided to get these for the kids. This is an 8" queen for our son. Much better value for a bad back than the major manufacturers with the high ticket price! Only drawback, the mattress needs to air out for a few days before use, as the mattress has a distinct smell. But once it is aired out, you would never know.

We ordered this mattress for our camper. Our only expectations were that it be more comfortable than the mattress that we had in there and for the price, we thought that was what we would be getting. It was a very pleasant surprise how comfortable this mattress was and what a difference it made! We both are very satisfied with this purchase!

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.)

Having tried some very expensive mattresses over the past few years, we have finally found a comfortable nights sleep. A (king) $200. mattress paired with the 2.5 Aerus 5 lb density topper is a little slice of heaven! We have owned the mattress for 6 months and it is awesome. We bought a second mattress and topper for our camper. Having spent thousands on Tempurpedic, which other family members now have, we wish we would have discovered this first. We are in our 50's with various back, hip and knee issues. Latex was too springy firm, Serta developed dips and hurt our hips, Tempurpedic was "wet sand" that you could not role out of...This combination of mattress and Aerus 5 lb topper works great!

We love this mattress. It is for our 3rd son and he loves it. He does not want to leave his room. We looked around at several furniture stores but they were all too expensive. This one is great quality and inexpensive. I would reccomend it to everyone. In fact right after I purchased it my co-worker purchased one for herself. :)

I researched thoroughly before puchasing and chose this one on foam density and price. I already had a 2in memory foam topper that is now on top of this mattress. The only bad thing I have to say is that it is a little too big and since I have a platform bed, it is hard to tuck-in the sheets and blankets.
