Floor savers slip over your chair or table glide & protect hard floor surfaces from damage including scratches & rust stains. They help keep rooms quiet by reducing noise when moving chairs & tables. They also reduce furniture damage by alleviating stress on joints. Slip-On Floor Savers require no adhesive & are easy to install. They are made of a vinyl sleeve with a reinforced rounded felt bottom. They grip the chair leg tighter with a passive locking system. Simply slide the floor saver over the existing glide on 1" to 1-3/8" round legs. Floor savers are recommended for vinyl, linoleum, wood, tile & marble.
