The kitchen cabinets that came with the house did not fit our storage needs. We had too much stuff, and the shelves did not allow easy access to stored items. The cabinet above the stove area (top two pictures) was too tall, narrow, and deep to be of much use for spices, or anything else. I designed an octagonal, four level rotating spice rack that has a full extension slide system. The new shelf allows me to rotate the entire shelf system while fully extended for easy access. The shelf system also rotates while it is inside the cabinet. Each shelf has a lip to prevent things from falling off when the system rotates.
