I have a free king bed frame from Restoration Hardware.
It is the Printmakers Storage Bed. They no longer make it.

If you google it, you can see some additional images. Dimensions at that link.
Color is black pine. Two storage drawers on each side.
Bed frame is in excellent shape.
It will be disassembled, you would need to come pick it up in parts.
