Just installed and assembled this adjustable bed.  Actually, it was my first purchase from Wayfair and I have to say the customer service is outstanding!  We got many notification of the shipment and a phone call from the delivery person a half hour before the delivery.  I will be ordering from Wayfair again!  But going back to the adjustable bed frame it was Easy Peasy to assemble (actually it was pretty much assembled other than screwing in the legs and placing the mattress bracket).  Warning though the box is HEAVY, so a couple strong people to move it is required (we used moving straps to assist in moving it).  Thank you Wayfair for a renewed sense of customer service.
