Martial Arts Flooring
"For what we paid, we got great mats. We use them for aikido (martial art) classes. They're obviously firm because they're new, but we hope they don't get too soft from weekly use. They're light, so it's easy to carry two sets of mats from the equipment room to the gymnasium." - Tse-Lynn
