The Best Dog Bed in the World can be placed anywhere, outside or inside it will function perfectly. This bed is a perfect size for a Great Dane or Mastiff. There is just enough give in the middle for comfort and superior orthopedic support, which is most important for older dogs. Our size XXX-Large bed is made with 1 1/2 " PVC Schedule 40 (Poly Resin) Tube, and can hold approximately up to 450lbs. Chew Guards are also made from Poly Resin Tubing and fit snugly over fabric around sides of bed. Material is a Vinyl Mesh Basketweave which is a 2 x 2 weave design. This means that two looms are weaving together to create this 1800 Denier Polyester material. Because it is a vinyl mesh weave you can fill a bucket with soap, water and scrub it down. Just rinse it off in a tub or with a hose, shake the water out and it is immediately ready for your pet to use. It will not matter if your pet is wet or day when they lay down on this fabric. UV Resistance is 1000 QUV exposure, slight color change. What does this mean in layman terms? This material will not fade unless it has direct sunlight outside of the atmosphere of the earth. No cracking after 24 hours at minus 40 degrees F, 2" ma. Height of legs is approximately 12" from floor. We cannot adjust the height of the bed higher or lower because it has been specifically engineered to the height we have it. Your bed will come disassembled. We will furnish you with detailed assembly instructions.
