Muffin is older; eyesight and hearing less and less.  She needs comfort and safety.  Plus a headrest...most important.  
I saw this bed, soft inside with a sturdy edge, and hoped it was what it appeared to be.
When it arrived I put it down and the real test started.  She spends at least half the time in this bed, head resting on the rim.
Good for her, REALLY good for those who love her.

Pros: well made, suits the intended owner.
Cons: ...
