This rack is top notch quality. It is extremely sturdy with heavy duty wheels that make it very easy to move about. The adjustable shelving are perfect for the large size plastic bins I am storing on it.  The price can not be beat and the addition of free shipping make the choice of this rack a no-brainer!!!  Hurry before they are all gone! BTW--the delivery man actually brought it into our home because it is a heavy item. Well done!!  I will be back for more from Wayfair!!
