Generally found as garden and exercise kneeling mats (be sure to make sure they aren't EVA). NBR foam is an elastomeric closed cell foam and has properties similar to "soft" EVA foam, but tends to come in thicker sheets (less adhesive and layers to secure and reinforce against rolling), compresses with more spring (less pain for the one being stabbed), resists shearing forces better (lasts longer and requires less reinforcement to prevent rolling), stretches less, and is overall more durable (doesn't compress out and die as quickly). NBR foam is generally slightly stiffer than EPDM.
