This frame cannot support a king sized mattress. We ordered one and it would wobble every time you got on the bed. I even tightened all the screws again several times. Then a couple months after we got it the center brace broke and the mattress fell down.
They were good enough to send a replacement, but after only a few days it is already wobbly again.
Way too wobbly for a king mattress (broke it)
