Improved high quality material: The chair cushion is made of polyester fiber, silk non-woven fabric, TPR base adhesive and release paper. This office chair mat is odorless, non-toxic and free of tin, lead and other metals. Recyclable materials ensure a healthy indoor climate. Non-slip and easy to move: The office chair mat is made of improved absorbent material, super non-slip, completely flat and stays in place, the surface is made of soft loop fabric like a carpet. This means the chair won't slide around like it would on a hard plastic pad. Provides excellent protection for hard floors: Size: 90 x 120 cm. This chair roll pad is perfect for protecting hard floors. Floor mats protect against wear and tear from wheels or floor coverings (e.g. tiles, hardwood, laminate, linoleum) and can effectively prevent noise from disturbing others. Hardwood chair cushions are designed for hard floors, not carpets. Easy to clean and store: Please place the computer desk pad on a clean floor before use. When not in use, it can simply be rolled up and stored without leaving any sticky residue on the floor. When used again, the adsorption effect is not weakened. Easy to clean and washable. Looks great and is a perfect addition to any office or desk. 100 percent guarantee: If you have any questions about our products, please feel free to contact me.
