I bought the couch ramps several years after I had bought the bed ramp, which always came with a railing. Although I wished the couch ramp came with railings, I bought them because I love the quality of DOGGORAMPS and the fact that they are made in North America. My dog, who will be 15 in May, is having trouble walking due to IMPA (doggy rheumatoid arthritis) and slipped off the side of the couch ramp. Fortunately, she fell on the pillow I had on the ground for just such a possibility and wasn’t injured. The side rails on the ramp have made a big difference in her safety; she now stands at the top of the ramp and centers herself before using the ramp.She and I feel very secure with the new side rails.
