I don't know if I will ever manage to get these mats to lie flat. They have been stored improperly before sale for so long that they are deformed. If they had not been a really cheap sale purchase I would have taken them back.
In my basement office the floor is covered with the puzzle looking foam cushions to add insulation. With a floor like that my chair just did not roll. The wood look veneer Matt works wonders to resolve this problem.
The sewing machine chair was marking up our engineered flooring so we needed something that would look good and not mark up the floor. This chair mat is great! This mat has no adhesives or grids that could scratch or mar the floor surface. We just plopped it down and voila we are now protecting our floor.
This mat looks good but it does slide around on my hardwood floor especially if the chair is off to the side.maybe all mats do this on hardwood floors. I bought it because of the price so it's quality matches what I paid for.
I recently purchased 2 of these chair mats and love them. Not only did I get an exceptional price on them they are just what I needed to put on the floor at my sewing tables to protect the tile. My chair slides easily from one to the other and they offer a bit of padding for when I am standing. Thank you!
