We love our new chair mat. It was delivered on time and was already laid flat. Usually a mat might be received rolled and then you have to let it lay out for a day or two to flatten-not the case with this.
I have low pile carpet and initially purchased the “Medium Pile Mat”. This mat was too soft so I upgraded to the “High Pile Mat” which works fine… If you are thinking of purchasing one of these mats regardless of your assumed carpet pile height I would recommend purchasing the high pile offering. This way you will be sure to get the stiffest mat available from this manufacturer. I cannot attest to how the High Pile Mat will work with High Pile Carpet.
The clear wide adhesive tape to hold the rolled mat together was excessive and extremely difficult to remove from the mat. I used 2 bottles of Goo Gone. Areas on the matt are still sticky.
