Chair mat, size 130cm x 160cm Material: Polyvinyl chloride Brand: SALLOUS Size: 160*130cm Color: Black Style: Dining mat Shape: Rectangular Rough embossed processing: The surface of the mat has an embossed treatment. This allows for smooth movement of the casters. The glossy bottom surface blends with the floor and prevents slipping. Noise reduction specifications: With a thickness of 1.5mm, the mat acts as a buffer for the floor when casters move on it, reducing the sound of the casters rolling. Heat-resistant material up to 85°C, allowing for use with floor heating. Functionality is not an issue, but there are scratches and stains due to aging. I will clean it as much as possible before shipping, but please understand that this is a used item and no claims or returns will be accepted. Please refer to the first image for scratches and the second image for stains. Regarding the stains, they are from the flooring agent of the floor where the mat was placed. I have carefully wiped it with a neutral detergent, but some residue remains. There is no stickiness. The stains are not on the surface, only on the back.
