The worst! They sent one person to do an obvious two person job. She tried her best, but was just not equipped to do the job. Had to come back again and still didn't get it right. My husband and I ended up taking it apart and putting it back together correctly. It was very heavy, which was the reason we paid for assembly to begin with. This was for a king size platform bed with headboard. Fortunately, Handy refunded our money since we ended up doing the job ourselves.
