I had some concerns with some of the reviews but after finding out for myself, none of them concerned me.  This is a fabulous shoe rack.  I don't have large feet so I got five pair a row easy.  You can even fit another row on the floor underneath the last rack with flat shoes for 55 pair usage instead of 50.  Boots or extreme wedges won't fit except for the top shelf, but super high heels will.  Hang the heel over the back rail and underneath the heel on the next shelf, put a flat shoe.  The bars and sides are sturdy and I was amazed at how compact it all was with 55 pairs of shoes, using the absolute minimum space.  It was incredibly fast to put together.  Even the screws are heavy duty.
