Memory foam is a unique polyurethane foam that conforms anatomically to the horse's body temperature. The foam in the pad is activated by the horse's body temperature, creating a perfect conformation between the horse and saddle. This saddle pad eliminates pressure points, stabilizes the saddle, and absorbs shock, making it more comfortable for your horse's back. This pad is especially suitable for use under dressage saddles. It can also be used under jumping saddles where the flaps might put too much pressure on the shoulders.
