We bought this bed frame to support a new queen size foam mattress instead of a standard box spring and we also wanted some storage beneath it. This frame is EXTREMELY sturdy! Having read all the reviews about assembly difficulties, we found it went together well if you follow the directions. You definitely need 2 people to assemble the queen size. The trick with inserting the crossbars is to be sure the small slots on the sides of the crossbars fit over the little pins in the slots of the side rails. Otherwise, the crossbars may seem too short or too long and you won’t be able to insert the rubber plugs that keep the frame sturdy and quiet. The frame seems to have enough storage space below to accommodate several plastic containers. Have only had the frame for a week, but will update the review if things change.
