So far it's working out like the one we had to replace that one lasted a couple of years but being plastic plastic does have a shelf life and gets brittle and cracks so if I get the same time with this one I will be happy
I weigh 155 and have a standard size chair. The mat is quite thin and the wheels of my chair leave pretty deep impressions and doesn’t easily move when I need it to. I would not buy again.
It works okay on my berber carpet. My chair had already made indents into the carpet so with the mat on top my chair tends to roll to where the indents were.
Happy to have one again. This one is for low pile carpet is softer then my last for hardwood floor. So far not sure if chair and my weight will create certain indents that may affect how much I actually like. I am noticing getting stuck a bit already. Time will tell. Hopeful!
