The Treasure Garden system of modular covers are designed to cover an entire sectional unit completely no matter what the configuration. To more easily connect sections and accommodate extra space between for larger pieces, you will need a Treasure Garden Extension Protective cover. Measuring 12" W x 40" D x 32" H, this cover is also made from the same durable RhinoWeave fabric in a champagne color that is mold, mildew, water and crack resistant and fully breathable.
