This bed is well-built, all the pieces fit together perfectly and they are reliably secured in place. The hardware is good quality and a tool for assembling the bed is included. The wood is good quality and the cherry finish looks nice. I placed a thin wooden board on top of the slats to provide a firmer support for the mattress. A standard size mattress rests on top of the bed freely and is not supported by the frame from sliding sideways or up and down.
