I purchased this frame to use in our guest room.  We have a king size (split) box spring and large pillow top mattress. I also purchased an upholstered headboard to use with this. I picked this bed frame because it was universal and adjustable. So the headboard fit because the frame adjusted to attach it.  It was a little heavy, but I was able to lift the box, carry it upstairs, and assemble it by myself.  It arrived slightly bent due to shipping. The piece that attached to the headboard was bent inward so it would not sit flat against the headboard.  But it was easily corrected with a hammer.
