The ramp it perfect size for bed or couch. It is one solid piece and does not fold for storage. The top has antiskid texture to help the dogs go up the ramp. I don’t think this hurts the paws but it is pretty rough. I would start the dogs out as young as possible to get them used to it. My dogs don’t seem to want to use it. They still want me to pick them up. Miniature dachshund mom.
