Satisfied
Style: Level 2 Medium 8" Size: Twin
Perfect length for my twin trundle, was initially worried about the length according to the reviews but it was perfect. It’s a little taller in height and it makes it hard to open and close but very comfortable.

Not the standard mattress size you would expect
Style: Level 2 Medium 8" Size: Full
I ordered a full-size mattress and it was smaller than the standard full-size mattress dimensions. We had to return it. Unfortunately, it did not fit the full size bed frame we have for our toddler creating gaps that were unsafe for a little one. So be aware if you’re buying this mattress and want it to fit a specific bedframe. The mattress is comfortable otherwise and nice to sleep on. We ended up using it a couple nights while we were waiting for a different one to be delivered and it’s very nice to sleep on. I included some pictures to show how much smaller it was than expected and how it did not fit our full size bed frame. ... show more

Shorter twin than standard
Style: Level 2 Medium 8" Size: Twin
The comfort of this mattress is perfect for my tween kids, but is shorter in length than a standard twin mattress.

Super comfy!
Style: Level 2 Medium 8" Size: Full
Great mattress! We bought this mattress for our guest bedroom & did want to spend a lot of money. We were a little skeptical at first purchasing a roll up mattress but any doubts would quickly erased. Mattress unfolded very quickly & filled the bed space. Mattress has a very soft top layer but enough firmness to support your body. I very satisfied with this mattress and would order another one if I needed it. ... show more
