Good helper for protecting joints of your lovely Furry friends! Our 4-tier foam dog ramp measures 28.5” x 16” x 20” (L x W x H) and loads up to 66 lbs, which is suitable for short-legged dogs or pets who suffer from arthritis, joint stiffness, or other mobility impairments, allowing them to climb up or go down the bed, sofa, or stool at will. It is filled with high-density foam and covered by non-slip corduroy fabric, so there is no need to worry about deformation. Besides, the cover with zippered can be easily removed for daily cleaning. In contrast to hard stairs and long-ramp stairs, our foam dog ramp helps reduce strains on pets’ joints while ensuring good safety.
