Somette 5-inch Double-sided Cotton/Foam Youth Twin-size Memory Foam Mattress

This is not a mattress, this is recycled shredded cloths, stuff in a mattress cover...Never buy this product. Worth XX dollars, not XXX.XX. My first and last order with overstock. Misleading picture and info...

This is not 5 inches thick. Better than a futon of similar price, but not 5 inches. For a child's bed, it's worth it rather than having to pay a bed company to deliver one on their schedule. But it is not 5 inches thick,

The mattress is definitely more like 3-1/2 inches thick. It is dense, but I added a foam pad and mattress pad to get a little more comfort. It is for my 4 year old, so being firm isn't that big of a deal. I only had an 8" clearance to work with under the bunk set, so this worked out perfectly with the low-profile roll out trundle frame I purchased with it.

perfect for younger guests- ok for a night if your full size. Better for platforms as opposed to slats.

I purchased this mattress for a trundle bed to be used when my daughter comes home to visit from college. Many mattresses that say they will fit a trundle really do not as they are too thick (I have many snagged and ripped sheets to prove this!) so I was specifically looking for one that was thinner. The mattress is probably closer to 4 inches after expanding but is not "thin" feeling at all. My daughter and another college-age friend both used it while home on spring break and both said it was very comfortable. It's also lightweight so would be easy to move and throw down on the floor for kids over watching TV, etc. Overall, a very good value.
