I have only had my bed for a few days.  It was easy to  assemble, basically screwing the legs on.  My daughter had it all set up within 5 to 10 minutes.  My lung was damaged in a car accident years ago and it was hard to breath lying down especially in wet weather.  My adjustable bed helps me sleep much better already.  I would suggest that you make sure your mattress is 14 inches thick as mine is only 12 inches and with my fibromyalgia, I felt a hard lump  where the motor and/or massager are.  So I'm adding a 2 inch gel foam mattress topper.   I would have given it 5 stars if the delivery  service had at least brought it to my apartment door, especially since I am in a wheelchair.
