The Sadi headboards have the simplest mounting system available ( Z-Bar technology ), that allows you to mount the headboard on the wall above the mattress. This is a new concept for residential use, but commonly used in hotels. The benefit is that you get the full view and comfort of the head board by mounting it base on the height of your mattress and eliminating the possibility of covering part of the headboard with a thicker, taller mattresses. Dry-wall anchors and screws are included for easy installation. The Z-Bar system is available in twin, full and queen headboards.
