Bully Beds were designed with one thing in mind, large dogs. Named after our 150 pound Cane Corso Bull, we tested these beds for over a year to come up with just the right foam and thicknesses to support and relieve a big dog's joints. We chose the best 4.5 lb medical grade orthopedic memory foam we could find and tested it to make sure it was durable and comfortable. This is the same memory foam used in high end mattresses. In fact, we designed these similar to those end mattresses that cost thousands of dollars, but tweaked the design to cater specifically to large dogs. Then we found a soft and washable cover that would last and protected the foam with a breathable waterproof internal cover. We also added a heavy duty zipper with it's own enclosure to prevent chewing and ripping by curious dogs. After all that, we decided to offer a 10 year warranty on this bed. This means that if the beds ever flattens by more than one inch, we'll replace it for you. We're confident this is a great bed for a great value that you and your dog will have for years to come.
