Pet staircase made from soft foam. If your four-legged friend has their sleeping or cuddling spot on the sofa or in bed, then this pet staircase with 3 steps is a useful aid. Simply placed next to the sofa or box spring bed, the sofa steps make it easier for your dog or cat to get up and down. The dog steps are made of soft foam so that your pets cannot injure themselves on hard edges. The polyester cover can be easily removed with a zip.
