This was such an easy setup, I did it by myself. I wanted to use the same headboard and footboard so I removed the slats that would hold the mattress, but left the side rails attached and set the entire unit inside while it was still folded in half.  Since the legs it came with stood an inch taller than the side rails if my existing frame, I attached them and flipped it over, inside the existing bed frame and it works perfectly.  I did try to follow the steps to lair the remote but didn’t get the three beeps I was expecting. So, I just hit the head up button. And saw it was already pairedworking!  Just needed to out in the batteries (included).  Love this purchase!   Mom comes home from hospital next week—- I almost don’t want to give her the bed back!  Haha
