I REALLY like this drying rack. It is well designed. The cross bars are light weight aluminum, which keeps the unit light as well, but they seem sturdy. 

The pieces did go together with difficulty - they fit very tight - but when I was having problems with them my wise husband used the trick of putting liquid dish soap on so they snapped together easy - and because of the way they fit, getting them apart again will not happen easily - so be careful to follow the instructions carefully. 
Once put together this thing is a design wonder! It folds down easily and rolls into a narrow space. the legs pop back out and the arms lift and with a gentle push, lock into place. I could see that over loading it with wet laundry - if not balanced properly might make it tip a bit but so far I haven't had a problem. 
I have been looking for a drying rack that would do what I need without breaking to pieces. So far it has done everything I asked of it. It meets all of my needs in a drying/hanging rack.
