I bought this to replace another mat which after 10 years had cracked enough to be coming apart. But this one has the same sag where the wheels are and holds those sags even though it was designed for 3/8" berber carpet. I suspect it will fail quickly and until then I'll need to "work" to move my chair from wheel sag divot to wheel sag divot. But it does protect the carpet!
much better quality than my previous floor mat - I don't think it will crack like my old one. No 'plastic' odor. I like the beveled edges too - nice addition that I didn't really think would make a difference - but it is nice. SUPER FAST shipping too - received it the very next morning.
