Home-made Waterproof Customizable 50"x32"x5" Memory Foam Dog Bed This dog bed has a net weight of about 21 lbs. We use high density of 4-lb memory foam for this dog bed making it difficult to be flatten out. There are many dog bed products from other sellers that use lower density (3-lb or less) and lower grade of memory foam that will sink in easily or degrade after a period of use. Thus, their dog beds are mostly half the weight of ours. Each dog bed comes with one durable water-resist external cover and one fully waterproof internal cover. The covers are easy to remove, clean, wash and dry. They are sealed with Velcro fastener instead of unreliable conventional zipper that are easy to break after a few months of use. This dog bed gives great comfort to healthy dog as well as providing therapeutic benefits and supports to injured (recovering from surgery, back pain, arthritis and other injuries) dogs and also dogs with incontinent problems. This is a Home-made waterproof dog bed that can support up to 175 lbs dog and it is size customize-able. Dog in picture weights about 65 lbs. We are willing to make changes or improvements to our product whenever it seem fit. Please contact me to customize (further cut-down/trimming) the dog bed size to your desire size. SPECIAL OFFER for a limited time - We will add an extra external cover when you place 2 identical size dog beds in your order.
