Tired of your furniture scratching up your nice floors? Or maybe it's just really hard to slide a heavy chair out? These Adsamm plastic gliders are the simple solution. You get 16 of them in a pack. Each one is a small, rectangular black plastic pad (18mm by 30mm) with a metal nail sticking out of the back. To install, you just mark the center of your chair or table leg, make a tiny starter hole (a thin drill or even a nail and hammer carefully), and then press or gently tap the glider's nail into the leg. Once they're on, they create a smooth, protective surface between your furniture and the floor. They work great on hardwood, laminate, tile, vinyl, and even low-pile carpet. They make moving furniture a breeze and prevent ugly scratches and scuffs. They're perfect for dining chairs, office chairs, table legs, stools – you name it. Good quality, made in Europe, and a super affordable way to protect your investment. Your floors will thank you.
