Very thin. Rolls up on the edges when weight is applied. Chair rollers leave grooves which makes the chair hard to roll. Edges are sharp and will cut you.
It’s an ok chair pad not sure it’s actually 1/8” thick but it will suffice for now. REALLY DISSAPOINTED in the shipping though NO packaging! Just the mat rolled up with a shipping label & taped around the middle!! We had to ‘wash’ the darn thing it was so nasty - surprised it didn’t get damaged. It’s a little sad to me that ikea carries the absolute best chair mat for about $18 but going there to get one is a nightmare & they charge $99 for shipping (!!). So this will suffice for a while.
I would recommend it. It’s very sturdy and durable. It fits perfectly the space that I’m using it in. It fit perfectly my chair and drafting table. Thank you for your service.
