Crushed Carpet Probs

Buy one of those plastic chair pads to put under your desk.

A friend in the carpet business for about 40 years claims there is no carpet over pad that will stand up to the abuse created by a rolling chair. And that even commercial glue downs will wear out there before they wear out in the traffic areas.

Yep. Search for "chair mat"

Get one of those plastic floor mats from an office supply store. They work great. I've had both the ones with the spikes and the smooth ones. I found they both worked the same for me on dense carpet.

I've seen hard plastic pieces that office chairs sit on...don't know if there is a name for them. Would look into this instead of replacing carpet.

Thanks for the answers. I wanted to avoid one of those platic mats because... uggggllyy. It's just that my old cheapo carpet had such a flippity-floppity knapp, that the beater bar would bring it right back. Everybody seems to agree though - go with the plastic mat. I'll give it a shot.
