Niubya Cooling Elevated Dog Bed Portable Raised Dog Cot with Washable Mesh, Medium (42"L x 30"W x 8.4"H), Brown

I liked this pet bed so much, I got a 2nd for my 2 biggest dogs. The first dog I got this bed for is about 40/ 45ish lbs, the 2nd is 65/ 70ish lbs and we got them both a Walmart size medium. They were very easy to put together for just 1 person without directions (though they do come with them). The first time my mom and I spent 5 minutes putting it together and we took an extra minute just because we didn't think to put the velcroed side on last. The velcro is thick and strong so long as you can get the material on tight enough. What we did was stood the bed up vertically with us and with the velcroed side facing us, we twisted the material around the pole while connecting the velcro. It helps to try to get 1 side of the velcro on first, then try to continue twisting the material all the way across. If the bed starts getting crooked, just remember you can even it out when you put it back on the floor. When ordering it from Walmart, pay attention to the dimensions in the title Walmart gives. Walmart stated they were medium sizes, but going by the PRODUCT'S details, it was a size large. I did pick the correct size the first time I ordered, based on what the dimensions the title stated. Make sure to scroll down to the pictured details of the bed to get the dimension details for each size and the top weight for each size. It definitely helped us understand which size to order when comparing the details.
