Soft, good scratching surface, and a nice shape
As with all cat beds, it's about where you put it as well as what sort of bed it is. We put it on a trunk in the living room window, and she went to investigate and dutifully scratched at the sisal, but no napping. I think it's currently too chilly, and in the summer she'll appreciate it as a spot for basking in sunbeams and watching people in the street. It's now on the floor by my bedroom radiator, and she is nesting in it on a regular basis. She's a small cat, 3kg or so, and fits in neatly.
