This is the Solid Based Lazy Susan. By solid, I mean that it isn’t hinged, or folding. Unlike the cheap 12 inch plastic ones that you find in the store, this one is a huge 22 inches in diameter and constucted with a heavy duty 3/4 inch Melamine product. If your kitchen cabinets are all white on the inside, this is the same type of material. It is designed to fit in your shelving that is a minimum of 22 inches wide and deep. Most lower kitchen cabinets and pantry stands are a standard 22 inches deep. Custom sizing is available. Please email for a quote. This Susan arrives to you fully assembled with the edging installed. The edging has a handy raised lip so that your items won’t slide off. This will make your storage space much more effecient, while allowing you very easy access just by spinning.
