This is a fun little piece of furniture to use as a floor couch or chair. I don't have use for a twin size bed but it would probably be okay for that as well. The color is spot on, a vibrant blue and I like the idea that you can take the cover off for washing. The packaging is amazing because once you take the mattress out of the box and wrapping, it immediately starts to grow and it is a solid 8” thick. It's comfortable to lie on or sit on and I think a child would love to have this in their room, or set it up in a finished basement for them. If you do use it as a bed, I would think it might be a little uncomfortable because of the gaps in the foam cushions, but that's just me, I'm old and particular, but I do like the firmness, and a child might not have any problems with this at all. It's a one of a kind, fun to own item that I'm sure your kids will love to call their own. The item I received had a very small hole in the cover but I can fix that easily enough. I think this would also be a great gift for someone who likes the unusual and still likes to sit on the floor.
