Every chair pad I've owned has eventually cracked. Their real value is measured by the length of time till cracking. Since I've had this one for only a very short time it's really too early to tell if it will produce the value I hope it will.
I thought this was a thick hard surface vinyl mat. Was disappointed when it arrived rolled up like a piece of thin carpet. Doesn't look like it will last for several years of heavy use but I guess only time will tell.
