I was a little worried about this purchase because I was purchasing it for a daybed whose dimensions were half an inch narrower and half an inch shorter than the dimensions of this mattress. I called the manufacturer and they told me that the mattress has a bit of give in the foam and that it would work. It worked perfectly. It took this mattress about three days to reach full height. I also bought the regular size mattress for the trundle, and that one seemed to expand to full size in about a day, so I'm not sure why this one was different. Maybe it's compacted more--it's bigger yet arrives in the same size box as the regular twin. Anyway, the mattress is super comfortable. Oh, I also asked the manufacturer if it has to sit on a solid surface (like a full board) because my daybed has slats. They told me the slats would be enough support--my bed has 15 slats with a couple inches between each one. The odor from the bed is pretty strong but not horribly unpleasant. It took about 4 days to dissipate to the point where I wanted to put sheets on it. My teenaged daughter has slept on it a couple of nights and says it's comfy.

This is a great mattress! I did have some reserves on buying this mattress because the price was low. I thought that a mattress with that kind of price had to be cheap. However, we've had this mattress for a month and have had no complaints. My husband and I enjoy it thoroughly and we have had such peaceful, restful nights with it.

Its hard to believe that you can take a king size mattress and lay it on the floor and go right to sleep and wake up with no aches and pains. Even better put it on a box spring. Awesome. I even had a memory foam topper that I put on it and took it off because this is better.

Replaced my teenage daughters standard mattresses with these memory foam mattresses. They arrived well packaged in a reasonable amount of time. Very pleased that the beds were packaged in their covers. Very little foam odor and expanded fully within 24 hours. Both girls love the comfort and support this mattress provides. They even provided me with great support when I tried them out! Great alternative to much higher priced standard innerspring mattress. Both in use on mates beds without the need for box springs.

It was just too soft. I kept sinking down in it.

Never expanded all the way after taking it out the box

Fantastic bed for the price, wish I would have bought one of these earlier

Was not 8 inches more like 5

Super comfy. Got for a bottom bunk bed for my son and I like it better than my mattress!

Quick shipping. Expanded correctly and very comfortable mattresses for my girls' bedroom
