1. Slip-resistant and stable when moving: The back of the chair mat is made of an upgraded adsorption material, which has good anti-slip performance. So, it's advisable to tear off the film on the back when using it and stick it firmly on the hard floor to prevent curling. Note that this chair mat is mainly suitable for hard floors rather than carpets. Its surface is a soft looped fabric similar to a carpet. 2. Protect hard floors effectively: This floor mat can help prevent the wear and tear of wheels or floors (such as hardwood floors, tiles, composite floors, linoleum floors, not suitable for any carpets or semi - carpeted floors) and extend their service life to some extent. It can also reduce the noise of rolling chairs, so you're less likely to disturb others even when playing games or working at night. 3. Made of environmentally friendly materials: The chair mat measures 48x36 and is composed of non - woven fabric and a PE film layer. It doesn't easily fold, curl, or fade, has little to no odor, is pet - friendly and non - toxic. There may be slight creases when using it for the first time. You can unfold the chair mat, tear off the PE film on the back, place it on a clean floor, smooth out the creases, and make the floor mat fit the floor well. 4. For space - saving and environmental protection reasons, the chair mat is folded when shipped. There may be slight creases when using it for the first time. Ironing with an iron can help remove the creases relatively quickly. Or, you just need to stick it on the hard floor according to the usage steps below the product, and it will gradually return to a flat state.
