I am using this right now for our 80 pound 12 year old lab to get up on the bed. Placing it on the mattress was too high so it is on the frame. Used treats to get her to walk up and down straight, keeping her nose to the ramp. Will move it to the van soon since she scrambles and slips on the cement to get in through the side door. She still can jump on the bed and into the van but is on daily NSAID for knees, hips and back pain. All the jumping makes her really sore. So the ramp works great if it is placed not at a big incline. The bed frame and van floor are about 12 inches on the ground.

Pros: no slip surface, light and foldable
Cons: Not sturdy at steep angle
