hello mbrew, i believe this carpet is seagrass.

Hi!

If you're interested here at Blackstone Carpets we have Soft seagrass which is a blend of Marsh grasses and other natural grass fibers. Made in the same process as Soft Sisal in a softer feel. Soft seagrass is the answer to the normal scratchy seagrass and comes in 3 patters. Only available at Blackstone Carpets a wholesale company.
