I needed a firm foam pad to make a full bed for my aging dog in the back of my suv. After spending a few hours researching and looking at Amazon, I ordered from The Foam Factory. The website clearly spells out the products and their differences. I called customer service for further clarification, and was able to quickly get through to a representative. The pad arrived on time and as advertised, and with no odor! Very pleased, and so is my dog!
