My husband and I put this bed together in under 10 minutes. It is cleverly designed with interlocking rails that require no fasteners. The bed slats are secured by velcro, and two of the slats in the middle have double-faced tape that keeps the mattress from sliding around. I have the twin size, which doesn't include a center rail, and the heavy memory foam mattress on top doesn't move around or cause the rails to sag, even with a 200 lb person in bed. Loads of storage space under the bed too. A short person may wish to get the 14" high version, though, because this bed is quite high (28" w/a 10" mattress on top). Very pleased with the quality, ease of setup, and price.
