Our dogs love their Kuranda beds and the quality is better than any similar elevated bed. They are guaranteed for a year even if chewed, though ours have held up several years already even though some of our dogs are really hard on them.
We have Huskies that chew them and flip them over and a Rat Terrier who wants to scratch a hole to China through hers. Yet, they have really held up. I am very impressed. I would highly suggest spending the money for a quality Kuranda bed rather than settling for substitutes that are not likely to hold up over time.
We suggest the indoor model unless you really need to use them outside in an uncovered area also. The indoor ones will hold water so if they will get rained on then you will want the outdoor one.
