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 just needed a 3 foot by foot plastic floor mat to go under my computer chair which is on a carpeted floor. Could not find any mats with these dimensions so I needed one which was firm/thick enough to support my chair with me sitting on it yet thin enough to cut the portion of mat which goes under my computer desk off because that area does not need extra carpet protection ( I don't wear shoes when I am sitting at my computer (TMI?). Works just fine and the price was right.
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..
