When Echo injured his back in a slip and fall he couldn't get onto the bed with me and so we had taken the mattress off and put it onto the floor where he could get onto the bed at night safely. I was getting pretty sore from that so Carol came up with the idea of getting this bed that folded up or made into a couch to put next to the bed serving as steps. It works wonderfully. Echo still has his back legs swing around as he walks but he is in no pain and seems to have adjusted well to his new disability. No wheel chair for this boy yet but he does have to go back to the vet to have more sebaceous cysts removed soon.
