Brought the chair pad home. Seemed OK but then I realized that not having a beveled edge is really important. If chair travels beyond the pad wheels can not negotiate the straight lip in order to get back onto pad. Have to lift the wheels over. Quite a pain in the neck. Also wheels make a fairly deep depression in the pad and chair does not roll easily. Should have purchased a better quality pad however store display only had strait edges in all price ranges. Will keep this one for a while but definitely will have to upgrade sometime in the future.
This is a near duplicate to one I purchased 6 years ago and which began cracking. It cracked where my front chair roller resided most of the time when I worked at my desk. No I'm not heavy - 170 lbs.
