This mat is just to supple and dimples with any chair pressure. This one might work for an industrial carpet firmness. I needed a more hard plastic mat for my carpet area. I just ordered the wrong mat for my needs. Staples was wonderful about the return and credit. I ordered a harder mat and should get that one in a couple of days. Thanks for your ongoing service and products!
OK for quality and price - would recommend the mat comes shipped in a box and not loose as it was dirty and had glued on shipping labels I'm still trying to remove!
Unfortunately the mat didn't work for me. As soon as I sat in the chair it wouldn't move because the mat sunk into the rug. Apparently there are different thicknesses for different types of carpet.
