(Queen size) A few items of note on this frame -- it has a load bearing capacity of 660 lbs -- which includes the weight of the frame (134 lbs) and I'm assuming the weight of the mattress.  Buy accordingly.  That said -- it seems much sturdier than the adjustable frame with massage that I'm replacing.  All the options work as they should and the frame adjusts to very comfortable levels.  Ordered Sunday, arrived Wednesday, set up on Thursday.  Easy set up - unfold, screw in the legs, put on the mattress, make the bed and you're ready for a good nights sleep.  I love it.
