Happy Feet mats feature a dense rubber cushion encapsulated within solid, nitrile rubber to protect against deterioration and contamination. This construction makes Happy Feet mats highly resistant to chemicals, animal fats and petroleum products. These advantages result in more comfortable, better wearing, longer lasting mats. Mats can help designate sensitive areas with OSHA color-coded borders; green for safety, orange for warning, red for danger, and yellow for caution. Happy Feet mats are available in texture-surface: for dry to damp work areas and Grip-Surface: for wet work stations.
