Dog stairs/ramp

[kmit]

I have 2 cavaliers, who both sleep on my bed. My older one, now 9, has become more reluctant to jump up and down by himself. He has no signs of pain, but my bed is 70cm high so it has always been quite a jump. I would like to get him some stairs so he can go up and down by himself, but I can't find any that are tall enough. I would also ideally like some that I can put sideways at the foot of the bed, as otherwise they would take up too much space sticking out into the room. Any suggestions?
