This frame is well designed and sturdy! I bought this for the basement playroom and extra bedroom for sleep overs and had to replace the frame several times, all metal frames that is! They never last, the come apart the welds break, so this time I bought the wood. The Chris Knight frame is solid, and no springs! The reason I'm giving it a (4) is you need help putting it together, Me, my wife and my son had to fit the frame into the slots, but after we finished it it looks great! I just hope it last a long time!
