Hi all, this is info for anyone who has an office chair which has to sit on carpet, and so you're forced to put down a chair mat, either to let it roll freely, or, to protect nice carpet. I've come across an absolutely great product, which replaces the caster wheels on an office chair, with highly polished sliding discs which are 5 inches in diameter. they keep the chair from creating carpet damage with squashed little indentions, and they also allow it to slide easily across any sort of carpet. you don't have to deal with trying to clean chair mats, and you won't have to trip on the edge of the mat. also, the chair itself is much more stable, and less likely to tip over, which is a new OSHA workplace requirement. you can google on the product name of "woda glide" to find a place to purchase them; they're $10 each. they plug into the chair base the same way the wheels do, so you just unplug the wheels and replace with these cone-shaped things of hard plastic with a polished slick sliding bottom. they look like they would work fine on hardwood floors, but they may scratch it, and they don't make any claims for being suitable for anything other than rugs. hth, Chip Check out the TABI resource web page at http://acorange.home.comcast.net/TABI and please make suggestions for new material. if you'd like to unsubscribe you can do so through the freelists.org web interface, or by sending an email to the address tabi-request@xxxxxxxxxxxxx with the word "unsubscribe" in the subject.
