The Tovolo Stack N Cool 3-Tier Folding Baking Sheet Cooling Rack solves the counter space problem that comes with batch baking. Instead of waiting for one tray to cool before pulling the next, you can rest up to four standard baking sheets across three vertical levels at once. Open wire on every tier lets air circulate around baked goods from all sides, so cookies stay crisp, bread cools through to the center, and desserts set up properly. Chrome-finished steel wire gives firm, stable support for fully loaded sheet pans straight from the oven. The rack measures 18 inches long by 18 inches wide by 10.75 inches high when expanded. When the baking is done, it folds completely flat for a cabinet or large drawer. Wipe it with a damp cloth and towel dry.
