Rolling desk chairs need caster covers on hard surface floors such as LVT and hardwood. Flexi-Felt and Expanded brands of commercial quality chair leg protectors have options for shrink to fit caster covers for chairs with hard plastic wheels. Available in packages of 10 to 250, these caster covers fit most standard desk chair wheels between 1.75-inch to 2.375-inches in diameter. Wheel size fit varies between caster cover brands. Caster covers fit tight to caster and provide a layer of protection between the caster and the floor.
