Review on Foldable Elevated Pet Cot With Steel Frame - Durable And Lightweight Portable Bed For Dogs And Cats To Play, Rest, And Relax Anywhere by Charles Alfian

I bought the large size for my Rott/Blk Lab 1-year old pup. The intent of the purchase was for training, to be able to use this either in the house or outside and to travel with it to the park. I needed something for her to 'place' on for training and to keep her settled and calm when we're out. This cot allows for 95% of that easily.The only reason I didn't give it 5-stars is that the large size folds in half and there is no 'lock' mechanism to keep it from folding in half when you pick it up. Mabel (my pup) is still in the 'training' stages, so at least twice a day, I pick up the cot from its inside location and carry it outside to the yard for training there. We work on her 'place' for about an hour at a time and during that hour, I'll move the cot to several outside locations and then back inside. The moment you lift it from the ground/floor, it begins to fold on its own. The first couple times of doing this, resulted in it banging against my leg, and nearly catching my fingers in the fold. Now that I know what to expect, I work around it folding up.so it works. I will also say that in order for it to be able to lock, it would need to have a bar running along the underside.and it does not. Having a bar running across the underside in the middle would likely make it uncomfortable for a dog to lay on, so this design is likely best. So .just a note to users.when you move it, it will quickly fold in half.be aware.When we go to the park, it's easy to fold the legs up and the cot in half and them put it into its bag for carrying purposes that way. It unfolds and sets up easily. Making sure I always set it up on a flat area of the ground when outside means it's sturdy and stable when she jumps on it to 'place'. When I release her from the 'place' at a distance, she bounds off it and surges into a run. The cot does move during this surge off because it's very lightweight, but it does not flip over, and this doesn't startle or phase her.Overall, I'm very happy with this purchase and find it a useful training tool.
