Wheel stoppers are made of high-quality, high-density environmental protection felt material. They provide shock absorption, pressure resistance, and noise reduction. Suitable for hardwood floors, carpets, and tiles. The bed stoppers can support a certain weight, protecting the floor from damage by immobilizing furniture wheels and preventing unwanted movement, helping to avoid unsightly marks caused by rolling wheels. The furniture wheel pad fits most beds with wheels, swivel chairs, sofas, pianos, and other rolling furniture. Two color options are available to match your furniture. Each package includes 5 furniture cups, offering broad compatibility—ideal for office chairs with 5 wheels or other furniture with 4 wheels.
