WOW! My husband and I are "big" people...we've got a huge chair, and this mat is awesome to support us and the chair under our desk. It's super well made, and aside from the fact that I ordered a mat that was too small for the space, I'd buy this over and over again. Very happy with this and how it looks under the desk.

Only the Megamat has the strength to smoothly support 230 lbs guys sitting in 60 lb steelcase chair on DEEP pile carpet. Because it's so thick and sturdy, it needs no studs on the carpet side. With a smooth back, it can be easily used on hard surface flooring too!
