The top rack does lean forward. although nothing has come falling off yet, it looks as though it might if bumped the wrong way. Spice jars are easy to use and see in to. the lids are not metal, they are plastic with chrome paint coating. the rack is metal though. unfortunately my tablespoon and teaspoon measuring spoons are too large to fit into opening, so I often spill a little when measuring. it adds quite a bit of style and professionalism to my kitchen though, and it has been complimented. I used a label maker with clear tape/black ink small font to make labels for the jars and it looks nice that way.
