This is a good fairly priced chair mat for a person who will not be subjecting it to day in and day out heavy duty use. This particular mat will work best on a low pile carpet. For light occasional duty in a home office it will do the job and preserve the carpeting. I am satisfied with it but having used these protective mats in offices I recommend that if you need a mat that will really stand up to office heavy duty wear and tear and abuse for five days a week go with the thicker more expensive mats.
Where this mat helped my chair glide easier over my carpeting indentations from the office chair wheels occurred within 2 days of receiving. This was very disappointing. I am now rotating the mat to help even out these dips.
