They can be used alone or stacked to reach 2 or 3 inches, etc. To stack, remove the rubber bottom and place the top section on top of another. Do not stack too high for safety reasons. - Versatile 1 inch furniture risers: Table risers help robots such as robotic vacuums clean under furniture and provide extra under bed storage.
