Excellent frame. Maybe change the directions a little.
My wife loves it. She is somewhat gratified to find a solution to what she thought had been a mattress problem all these years. I didn't look at the front page for instructions. I thought I might be doing it wrong and, sure enough, I had to undo and redo the frame because I assume all of the Velcro would be on the top and only found out I was wrong when I tried to put the cover on.
