This mat is specially designed to protect your floors from the wear and tear caused by continued use. Not only do our chair pads provide unparalleled protection, they also ensure a smoother, quieter ride. The pad prevents the office chair from sliding and coming loose, while the non-slip bottom keeps the pad securely in place. This provides you with a noise-free working environment, allowing you to focus on your tasks without any distractions. Non-slip, non-toxic, odorless, anti-creep, colorfast, suitable for carpet, hardwood and tile floors, easy to clean Size: 120*90cm Weight: 2.2 lbs. Color: dark gray Material: polyester polyester Material bottom: TPR non-slip material The following are two effective methods: Soak the cushion in water and hang it to dry. The weight and gravity of the water will help eliminate wrinkles. You can also use an iron on low heat to iron out wrinkles. Be sure to place a cloth between the pad and the iron to avoid direct contact and potential damage. Once the wrinkles are gone, the office chair cushion should be smooth and ready for use.
