Needed a guest bed. for my guest room and did tons of tons of research to find exactly what I needed for the space and for the needs of my guests. This bed was really simple to put together. I did it by myself in an hour or so. The instructions were included and very clear, every piece fit perfectly, and has great storage space underneath. I do know that this bed says it uses a bed spring, but I agree with other users that it really doesn't one. Even a basic twin mattress seems to fit perfectly without one. I think with one, it would be too tall for the height of the bed. Other than that, it's great as-is!
