There are several size combinations of this rack. I chose the 20-pair rack. It isn't heavy and stays together while moving it into place. I have size 8 feet so my shoes are a bit wider and 20 pairs are very tight. I put wider pairs heel to toe instead of side by side. Once filled, the rack is very stable. If you (or anyone else in your house) expect to kick or lean on the rack a few times per day, consider a heavier rack. I am quite satisfied.
