Homeowners must factor in the cost of carpet padding (or cushion) when installing new carpet. The right grade of carpet padding is essential if you want to get the most out of your carpet in terms of comfort and durability. And it’s not just a case of choosing between a cheap carpet pad and a more expensive one. Different pads will be specifically designed and better suited to a certain type of carpet. Most padding is made of foam or rubber but within those categories are many sub-categories including high-density foam, urethane foam, memory foam, slab rubber, waffle rubber and more! You should check the carpet manufactures recommendations to determine the right pad to use.
