Comfortable Design: The foam dog stairs are designed to be placed directly against the edge of a bed, sofa, or other furniture, allowing your pet to climb up and down comfortably. Joint Protection: The dog bed stairs provide strong support for your pet while walking. The low-angle ramp design can better protect your pet's joints. Easy to Disassemble and Clean: The dog ramp features a zipper design, making the soft cover easy to remove for machine washing. The foam core can be spot-cleaned or lightly vacuumed. High-Density Sponge: Compared to other foam dog stairs, our dog stairs and steps are made of 30D high-density sponge, capable of supporting around 50 pounds of weight. Suitable Size: The pet ramp measures 33 inches in length, 15.7 inches in width, and 22.6 inches in height. It is suitable for small to large pet dogs/cats and can be used as a portable ramp for high beds and sofas.
