I would have given it 5 stars but I think the height/consistency of my carpet (even with the mat) is still an issue for my chair to roll over it. However its still better than my chair attempting to just roll across carpet lol.
Really disappointed. My chair leaves large circles anywhere it rolls to for any length of time. Hard to roll out of the indentation. Defeats the whole purpose of why I got a chair mat. Need to return it but have to take back to store as can't leave on my front porch for days on end waiting for pick up.
