To call this a floor mattress is a stretch. I ordered this to use in my daughter’s room for when she has sleep overs or when she wants a “sleepover” with mom ). This is more of a futon mattress and not a floor mattress, floor mattress shouldn’t be included in the description at all. It made the floor a little more comfortable than sleeping on the carpet but not as much, I think there are more comfortable options out there. It came vacuum sealed and reached full thickness in about 24 hours. I expected it to be softer and more cushioned. It also had a really bad smell right out of the plastic, a really bad chemical smell. I let it air out for a few days, the smell faded a little but it is still there. I noticed it had a zipper which I thought would be good to wash the cover but it seems difficult to remove as you can see in the pics. It’s attached by a string on the inside via multiple holes. Overall, I would recommend as a futon cover but not a floor mattress. Stars were removed due to bad smell, unable to remove cover easily in order to wash and item not meeting expectations. Hope this helps. Happy Shopping!
