This set is awesome!. The size I ordered is a Full. Once I set it up I could not believe how comfortable the mattress is .It was not high enough for me (personal choice), so I put it on a metal frame and now it's perfect.  The box spring was easy to assemble but,  it  took a little time to set up. They sent a small hand tool (key) that I quickly exchanged it for my ratchet tool. I would buy this again in a heartbeat.
