This is my second purchase from Just Chair Mats. The products are extremely well built and have held up over time (>1 year). I like the thickness and cleats on the under-surface. You simply cannot find a better built product. Sure there may be cheaper products, but they will end up falling apart. My first mat is as good as the day I bought it. My most recent purchase is for my son who is at his desk 4-5 hours a day. The carpeting in his room is brand new and quite thick, he loves the mat and the ability to move around with ease. I ordered my latest mat about one week after Houston had been hit by the hurricane and my mat arrived to me sooner than advertised. I highly recommend these well built,thick, durable chair mats, especially if your floors have thicker than usual carpet or you want to protect beautiful hardwoods.
