The cart is very light weight and seems pretty sturdy. It expands and retracts very easily. It comes with a tray to fit in the hole the expansion leaves on the top, also covering the rails that enable the expansion. However, the rails on the bottom shelf are revealed when expanded. It would be nice to have 2 trays to cover both rails. The baskets are great and a good size. Two wheels were broken in shipping, but Overstock.com took care of the issue and sent me two new wheels very quickly. The broken wheels were replaced fairly easily. I think it's a great purchase.
