Got this in the king size and i made a great choice!!! Its a full metal frame with three rubber wood panels one on footboard two on headboard absolutely sturdy and no noise at all great design cause see my kids are a little wild and crazy and when the adults walk away they seem to destroy everything with zero recollection of how it happened ! So we have gone through more bed frames than one should count in a 12 year span so researching and reading specs i found this frame and liked  that this frame holds 1000lbs also the design of the slats they dont screw side of the bed like usual frames but fit into notches where the frames rails and center support hold the slats i think this frame may be impossible to break !! And surprisingly the color of wood is better in person than as pictured i planned to change the wood color but we like it !!
