Despite being intended for medium carpet which I have according to the given depth measurement the chair wheels still create depressions after sitting for a while making it difficult to adjust the position of the chair slightly.
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.
I really wanted to like this mat. SADLY the vinyl is too thin and too soft. After sitting in my chair the wheels created divots and got stuck. I Could Not Roll or Move without physically getting up and moving my chair.Once in a new position the same thing happened. Did not serve the purpose..
