Very sturdy and exactly what I was looking for. It gives plenty of under-bed storage space. I used this frame along with a king size memory foam mattress. For under my mattress, I went to home depot and purchased two wooden slates cut into twin size pieces to use as  bunkie boards. The gaps between the metal pieces are quite wide, so you will need it. Also this bed is compatible with most headboards. It does come with the holes needed to attach.
