Boy did I hit the jackpot!  Read the reviews and purchased two sets to store seasonal clothing.  Unfortunately, they did not fit underneath any of my bedroom sets, so they went on upper shelves in the closet.  The storage cubes hold quite a number of clothing items and I did not over stuff.  The sides hold up well and zippers pose no problems.  I like the fact that one can see what is stored in the bin through the clear zippered cover.  I highly recommend this item and I plan to purchase one more set.
