The primary user of this bed is over 250 pounds. His last bed's cross supports eventually broke under the weight. This Queen bed frame should last a long time with its 750 pound capacity and 6 leg supports. It assembled under an hour. It comes with vinyl floor protectors. It has manufactured wood slats leaving less room between the slats increasing its support of the mattress than steel slats would. It is recommended for a 12" mattress, we used a plush-like 14". 
Altho, it has only been a week, we feel that this frame was the best solution.
