I found the footrest, flimsy in construction, it collapsed on the first day due to the screws holding one of the adjusting bars coming out of the 3 ply. I replaced the screws with slightly bigger ones and put a thin strip of wood behind the board to prevent points of screws from ripping the foam and digging in to my heels. Two days later, so far, so good. Also, the little dome feet are so smooth so as to allow the footrest to slide across the carpet when in use. I removed them - less sliding now. I think this product it far over-priced tat and I wish I had read the reviews before buying. New buyers beware!
