First, the frame is 1 inch to short. That may seem like nothing but. The corner pieces that hold the mattress in place can’t be on the base with a mattress on it. They just pop off constantly due to the pressure. 
Secondly. It often doesn’t work. I’ve had it two months and I’m beyond annoyed. At this point I have a platform base. Not adjustable. It was a pain to haul up the stairs to my apartment.  Unbox. Put together in my room and then find out about the 1inch defect. I would have had to take it apart. Pack it back up and haul it down the stairs myself as they use a service that only drops off outside the building. They wouldn’t even carry it upstairs to my apartment. Returning it seemed beyond impossible given the subpar delivery service. Don’t waste your money.
