I use this for fish tanks, I got the 4 shelf, looking back I would have gotten the 5 shelf just because I think it would work a lot better for me. But over all this shelf is amazing! It can easily hold a 20L fish tank on each shelf with a little bit of room for an air pump. Each shelf can hold over 200 pounds which works perfect because a 20 gallon tank is about 220 pounds, it is very sturdy and I don't have any problems with it falling apart or not being able to hold the needed weight. It is a little hard to put together even with 2 people working on it but once it is put together you are set!
