I didn't have a hard time putting it together like some reviewers stated they did.  The distance between the rows is a tad short.  My wedges needed to go in sideways to stand them on the shelf. The shelves themselves have a grippy surface so your shoes don't slide or slip off.  It seems a tad wobbly when rolling it.   Maybe I need to put more shoes on it. I sense a shopping trip is in order.  The wheels are a nice feature.  They make it a breeze to move shoes out of the way when vacuuming the walk in.
