This durable insert is for placement in a Sassafras mat frame or tray, sold separately. Swap mats seasonally to keep things fresh and fun. The charming design is heat sublimated onto the polyester and rubber insert. Suitable for indoor or outdoor use, the insert can also be used on its own as a stair tread or small floor mat. It is mildew resistant and features an anti-slip backing. Spot clean with soap and warm water or hose down. For best results display your mat in a covered or sheltered area to prevent fading.
