Also- I believe most of the replacement carpets sold in North America are all made by ACC?
And definitely get some samples- they ship em out quickly. Different lots will produce slightly different shades of the color you are looking for.
I put the Mass backing on mine- but there is jute attached to it as well... so not waterproof (see pic). I also used a sound deadner- maybe overkill but quiet and cool inside!
