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.

We bought one for each of our girls, who are in high school and college. We have a TempurPedic we love. The girls wanted a matttress like ours. This mattress is very comfortable! We have only had them a month, so we can't tell you how well they will last. However we are extremely pleased with the comfort. Our standard twin sheets fit on them. Both girls love them.

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.

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.

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 really like the way they ship in small box so that I can move to it to second floor all by myself. It's been over 3 weeks to use this bed on my platform bed frame bought from Ikea store. It is not smooth as expensive memory foam beds but still soft enough for me. One thing I do not like is it's little bit warmer than my old spring bed.

The twin came in a box that had the rolled mattress inside, in a sleeping bag type of packaging. It was compressed, which made it so easy to handle. When I cut off the plastic covering, it expanded to a wonderfully comfortable bed. I have it on a daybed, and it is as comfortable as my Tempurpedic. The price cannot be beat. Directions are included to tell you exactly how to carefully unwrap it. Very simple and quick. I am so happy with this purchase and would buy others if I needed them for my other bedrooms!

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.

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!
