Kings Brand Heavy Duty Metal Adjustable Bed Frame Center Support System, Queen/King/Cal King

Straight forward assembly; the rubber leg upper needs to be driven into the frame leg. I used a rubber mallet on the foot bottom to drive them partially into the frame leg, then unscrewed the foot and hammered the rubber bolt anchor so as to not chance damaging the floor/carpet protector on the foot. But no problem,

This is a hunk of junk and a waste of money and time. No instructions, poor quality, and nonsensical design. Please heed these words before your purchase of this subpar product!

Didn't support weight of a small preteen. Metal bent

I love this product! We used it to replace the wood boards the box spring and mattress sit on. It is made of very sturdy material and well worth the price. We've bought them for all our beds!

Not the best of quality but you get what you pay for here. Adjusting the legs is a bit of a pain compared to what I already have installed but i only needed one for my bed so it got the job done.

Worked perfectly for our queen bed frame. We had lost the middle support bar and replaced it with this one and now the bed is comfortable and solid. Very easy install, better then the original.

Another useless expense if u bought a bad bed. the base is rounded and tends to sway towards the side you move.if only the base was a wider circular base that sits comfortably

Easy to assemble, very sturdy. It has 2 adjustable braces that attach to the frame and rest on the floor. It may need a center support since the 2 braces are on the far side of the frame, for extra weight support.
