Upgraded MaterialOur chair leg caps are made of high-quality thermoplastic rubber, environmentally friendly and odorless. Unlike 1mm thick silicone chair leg protectors on the market, our silicone chair leg protectors are thickened to 2mm, making them more durable and flexible. When stretched, they will not fade or tear. Thickened felt layerThe 10mm thickened felt pad is strong, wear-resistant and durable. Our chair leg covers with a layer of felt protect furniture legs, parquet and tiles from scratches, dampen sound and prevent impact. The felt layer on the bottom reduces resistance so that the furniture can be moved easily and quietly without having to lift it. Good adhesion feltThe felt layer of conventional chair leg protectors is bonded with a gel. It's not sturdy enough, so the felt pads can easily slip and dirty the floor. With our upgraded chair glides, the felt layer and silicone are made in one piece, gel-free, nail-free. You don't have to worry about the felt layer falling off. UniversalSuitable for chair legs with a diameter of 14-19mm or 19-25mm. Please measure the diameter of your furniture legs before purchasing. Our chair leg protectors are suitable for sofas, tables and chairs, cabinets, beds, coffee tables and other round furniture legs. Easy to AssembleChair leg socks are easy to twist onto furniture legs. Just slide them over the legs of your chair and they stay in place! The chair legs do not need to be cleaned. When furniture protectors get dirty, they can be removed, washed and reused without spending any new money.
