My dog loves this bed. Initially I bought a more expensive dog cot in which the tubing around it was metal, it broke after it tilted and slanted funny. This bed is perfect it's super light weight but very sturdy. Easy assembly. I've already ordered a second one to keep on the deck and use in the car.  My 85lb dog fits on a medium but I've ordered a large onr because he like to stretch out. The medium is better suited for my other dog who is only 60lbs. The medium fits fine in their kennel.
