Floortex® Ultimat® Polycarbonate Lipped Clear Chair Mat for Carpets up to 1/2" - 35 x 47"

This fit perfectly when tucked all the way under my desk in my spare room that I use as a guest room and office. It's made of hard and stiff plastic, not bendable plastic. The spikes on the underside are quite sharp and sturdy so this is definitely not good for hardwood or tile. Now my chair slides around with ease instead of getting stuck on the carpet, very pleased.

I received the Floortex Cleartex Ultimat Chair Mat from the Spark Reviewer program to try out in exchange for my thoughts and opinion. It came shipped in a large flat box with cordboard on each side to protect from any sort of bending during shipment. I am rather please with this mat. It is a perfect size for your office chairs at the size of 47 X 35. This size allows for a extra lip that goes under your desk and that your chair would sit. It's a perfect fit. The bottom comes attached with little spiky nubs that go into the carpet to help with any type of sliding of the mat. I have had no problem with any slippage at all. It hasn't pulled my carpet or left any snags where it has been placed. It seems to be a heavy duty plastic. I have had it almost a month and so far no cracking. It has helped the mobility of my chair in my office. I would highly recommend this mat if you are looking for something under you chair. If I had to replace a current mat, this is one I would definately go to.
