Ok, there were incomprehensible delivery problems (which had me tearing my hair out) with my order of plain thick rubber matting, and the matting took too long to arrive, but Richard O'Connor, The Marketing & Strategy Director at First Mats, stepped in and I finally got it. The good news is that you really can have the matting extra thick, which is what I wanted. Much rubber matting out there is flimsy and has various designs on the surface. I didn't want that, I wanted plain and 1 1/2 inches thick, for putting on the floor of a vocal booth and also under a noisy printer, etc, and that's what I now have. Please be aware though that if you order it thick, even a small rectangle of it can be surprisingly heavy because rubber is a very dense substance. Also be aware that density makes it hard to cut up (so maybe pay extra to have the company do that to your specifications), and also be aware it has a noticeably strong smell in its 'naked' state. But if you want plain rubber, that is thicker than what's normally out there, then that's what you can have.
