I bought two of these over 7 years ago and just now have ordered replacement covers. My two large dogs stay outside during the day and these have been in constant use every day. Only recently did they start to show signs of wear. So easy to keep clean too - just hose them off! The dirt and sand the dogs pick up just falls through - so they are cleaner too! At first it took them awhile to try them and trust them, but once they did, they both used them all the time. Fantastic product for a truly unbelievable value.
I have three dogs 65-80#. It took a long time before they could try it but now it's in demand so I'm buying a second one. I have an old lab mix with a weak rearend and she loves this bed. It's off the ground so it's easy for her to get on and easy to get back off and be able to stand up. The other plus is that we are in the desert so The airflow is great in the summer and it's less likely anything will hop, slither, or crawl up on them while they're napping.
My dogs love it that I had to by another for my other dog. Its been outside all year and it's still in great shape. Very happy with product and so are my dogs.
