This is a horrible product.  We ordered two twin headboards for a place we were renovating and furnishing.  It took us a couple of months to finish the renovation.  By the time we went to install the headboards, we quickly realized the holes to mount the headboards to the metal frames weren't drilled incorrectly.  So we tried another twin frame... same result.  We even purchased a new twin metal bed frame in hopes it would work.  It did not.  Now that we realize these twin headboards don't work with twin metal frames we're out of luck because our window to return these poorly designed headboards has passed.  Hoping to find somewhere we can reach Joss & Main to explain the situation.  But do not purchase these twin solid wood panel Vienna Cane headboards.  They do NOT fit twin metal frames!
