Protects the carpet decent chair mat. I wish it was a tiny bit thicker. I weigh 200 lbs and after sitting for a few hours the mat does develop some leg divets. The go away by the next day but they are annoying after they've developed and you want to move your chair while sitting.
Chair gets caught on the lip of the mat and even tho we considered the bamboo because of the hardness in a couple of weeks time it has already sustained chair wheel marks. I do love the color tho. The dark brown blends in well with our dark brown carpeting.
The mat looks great on the new hardwood floor in the home office. The slightly textured backing minimizes sliding yet is clear enough to see the hardwood underneath. I would recommend this product to anyone looking for hardwood floor protection.
