This whelping pad is the finest you will find on the market. We can make it any size and any of our fabrics. The one shown is a 36" x 36". The bumper is 11" high and has ties on all corners as well as in the middle. There is a top stitch that goes aroung the middle of the bumper to keep it more stable. The bumper is sewn to a single ply of our middle weight fleece. We offer a second way of being able to buy our whelping pad The pad is made with two plies of fabric topstitched to keep it together. One ply is our very light weight fleece we use on our coats. The is sewn and topstitched to the same fabric that is used for the sides. Making the whole whelping pad much lighter weight and easier to wash. It also makes the whelping pad reversable. Our whelping pads are totally machine washable and dryable. Call us for your different options on fabrics and sizes. We make these to order. Testimonial: Dated 12/28/2010 Sheena: The very beautiful bumper pad arrived today.
