not very many at all. the cloth starts to rip off, so we removed the cloth (maybe youre supposed to anyway), and now there is a rubber sole- which is fine other than the "soles heal" has a little plastic square that is falling out- revealing the insole. Ich habe die Schuhe eine halbe Nummer zu groß gekauft - nicht so schlau. However, when I went to put clothes on the racks I had both levels about half full and came home one day to see that the plastic bits which connect the lower rod had snapped in half. theres only 2 things i can think of that are big minus for me. Love the two tone, and it?s great quality. They were a very easy install, and I was able to maximize my space! I am not a lightweight, and this table supports me without flexing or creaking at all, now that the top is on tight, theres no worries that It will easily support a 90-pound press weighing less than half of what I do. These seem to have held up great. Messed up on the color.
