A pet bed that includes an enclosure having a perimeter wall and a floor, and a cushion. The cushion includes a pliable external shell that holds several helical springs, each helical spring being individually covered in a flexible bag. The shell and springs are in turn held within a pliable casing, so that the cushion nests within the perimeter wall, so that the cushion provides variable support to a pet on the cushion by allowing the individually covered springs to flex independently of one another.
