These Carpet Bonded EVA Foam rolls are the top of the line when it comes to gym flooring. Measuring 6 feet wide by 42 feet long by 1 3/4 inches thick, these Tri-flex® rolls offer superior shock absorption due to their layers of cross linked polyethylene and EVA foam layers. The 26 oz. top carpet layer is the strongest and softest material on the market. These rolls can also be layered on top of new or existing larger open cell foam layers to create a flooring system similar to those found in competitive gymnastic settings.
