Very very hard to assemble.There is no zero gravity position available.The feet does not lift to 45 degrees for sure.Whenever you attempt to lift the feet portion of the bed ,the clamp in which the mattresses is held in position comes off.More than money it is a pure waste of time.I dont want to return this as I cant do the assembly on another adjustable bed! I am just using this as a weird box spring as of now!
