While the bed provides a little more support than a typical bed for dogs, it's very noisy (crackles) when our 50 lb. Keeshond is walking on it, trying to find the perfect sleep position.  

Pros: Thicker than normal, cheaper beds. 
Cons: Makes a lot of noise, which is why we have it in the living room versus our bedroom. We bought a different one for our bedroom for our dog to sleep on at night.
