Dog Trainer Recommended - 10,000's of Satisfied Dogs & Owners Why are Pet Support Systems beds hands down the best orthopedic dog beds you can buy? Because our beds are born from the same research and experience as our high end luxury therapeutic mattresses, costing thousands, sold in luxury retailers across the globe. From the same loving hands of our Southern California craftsman come the world's finest pet beds. What you should know when purchasing a quality dog bed... 1. Foam – ALMOST none of our competitors on Amazon are using US made certified foam, means they are using imported foam (likely Chinese). In order to make money they use an inferior, cheaper foam, which means it will break down much quicker than our Certi-Pur foam. Your Pet Support Systems bed will last far longer without degradation. Also, the imported foam has very little to no regulations and often has a bad (sometimes toxic) odor (check our competitors reviews), ours does not, it is certified non-toxic. 2. Construction - You are looking at a Premium XL dog bed which means your dog probably weighs a lot. Your dog requires comfort and support and that is why it is necessary to have a 2" HR support layer and 2" memory foam comfort layer. You do not want a 4" all memory foam dog bed (especially imported memory foam that is not really even a 3 lbs. foam). We use a real premium heavy duty 4 lb memory foam on top of a truly supportive base foam, which will last for years. One feel of our beds and you will recognize the difference. The result, a scientifically supportive bed for your aging dog, great prevention for your puppies as well. beds reduce pain, improve sleep and quality of life.
