【Floor Scratch Prevention & Noise Reduction】 This product uses a double-knit fabric and a thick felt bottom to firmly protect chair legs. It allows for smooth movement without scratching floors such as flooring and carpets, and also reduces annoying dragging sounds. It protects your precious floors from daily use and maintains a quiet and comfortable environment. 【Built-in Non-Slip Silicone & Difficult to Slip Off】 High-quality silicone material is used on the inside, perfectly fitting the chair legs. It is designed to be difficult to slip even after long-term use. Compared to conventional products, the "difficulty of slipping off" has been significantly improved, eliminating the stress of having to put them back on repeatedly during use. 【Excellent Elasticity & Compatible with Various Leg Types】 The stretchy fabric is compatible with a wide range of leg circumferences, from 6 to 18 cm. It fits securely on square and round legs, as well as thick and thin legs. It can be attached regardless of shape, so you can easily use it on various furniture throughout your home. 【Easy Installation & Easy Care】 It can be easily installed just by putting it on like a sock, and it can also be removed smoothly. In addition, it is washable, so you can use it repeatedly and keep it clean even if it gets dirty. Hand washing is recommended, but if using a washing machine, please put it in a net. It is very economical because it can be used repeatedly.
