The best space saving rack that I've ever had. I have my microwave on the top shelf, my convection oven on the middle shelf (with pizza pans stored on top of it), my large flour and sugar canisters on the bottom and 8 large Tone's Spice jars across the small top shelf. Amazing storage within a small space.  I am so pleased. So easy to put together even for this 70 year old lady, all by myself!
