Our silicone chair leg protectors are made using special technology that combines felt and silicone into one inseparable piece. This eliminates the need for gel and nails. The package includes 16 pieces of these protectors. The protectors have a common size, with a circular diameter ranging from 1.61" to 2.09" (41-53mm) and a square side length ranging from 1.27" to 1.64" (32.2-41.6mm). They are suitable for chair feet with a perimeter of 5.07" to 6.56" (128.8-166.5mm). Installing them is easy, as no tools or cleaning of the chair foot is required. They are also not easy to fall off. These chair leg protectors serve multiple purposes. They cushion and protect hardwood floors and tiles from scratches, reduce noise, and prevent bumps. The felt pads on the bottom reduce resistance, allowing furniture to move easily and quietly without the need for lifting. The protectors can be applied to various shapes of round and square chair feet, making them suitable for use on restaurant chairs, terrace chairs, kitchen chairs, and metal bistro chairs, among others. When you need to disassemble the product, you can continue using our chair leg covers at your new place. If they get dirty, they can be washed directly with water.
