Unfortunately, the only available instructions are for a full or twin size bed with a single headboard piece. If you order a king size, there are two headboard pieces that must be drilled together, but without any indication as to where. When I called customer service, they indicated they did not have the proper instructions either. Be prepared to get creative and drill holes where they’re supposed to be already, buy/use other parts to construct your frame, etc. So unfortunate for the cost. Wish I could get my money back.
