We ordered this headboard in dark gray, king-sized for our split-king adjustable memory foam bed. We do not have a box spring since it is memory foam and the headboard looks great. It took a little longer than expected to attach it to the bed frame with the special brackets we had for the adjustable bed, but in the end we got it attached. We were also able to add extra washers so it sits further back from the frame so when we adjust the mattress to a sitting position, the mattress doesn't rub against the headboard at all. Overall, we are very pleased.
