We bought this for our 11-year-old granddaughter for Christmas. She's an artist with a small "studio" in her bedroom. Not only does this allow her freedom of movement with her chair but it also keeps paint from the carpet in her room!
good mat that may last a few years. Already has some dents where the chair wheels roll. Happy with the price match I got in the store compared to online pricing.
I bought this matt to allow a chair to slide on my wooden floor and not damage the wood floor. (The chair does not have wheels.) It does not work. The chair sinks into the plastic and is locked in place. A dissapointment. I will use it with a wheeled chair under a different desk. Sigh.
