I just wanted to keep my chair from ruining my carpet. I think this fits my needs perfectly. Others say its thin and chair wheels get stuck. Well I weigh 210 and sure it sinks in a little. But it still roles out easily. This size is also perfect for my to sit in a roll up to my desk and not take up too much space on the floor. I'm happy with my purchase
the mat is very thick. It does not sink into the plush carpet. I have a computer table sitting on it and it does not wobble. I am very pleased with this mat.
This is a great chair mat. It came rolled up but flattened out very quickly. I have medium deep carpeting in my home office and it works great with that pile. I purchased this size as I wanted enough room for my chair to move around and it satisfies that need very well. It is just too wide for my desk! LOL But that's OK it spans the front of my desk and the lip provides me with a place to rest my feet. I recommend this mat just measure the width of your desk first! :-)
