I have 2 sets of stairs. Well, 3 but my sister is borrowing 1. 2 sets of homemade, and 1 we bought from Petsmart. One for our couch and one for our bed. Our couch and bed are VERY low.. but Izzie has LP we don't want her jumping. She is so spoiled now she rarely even tries to jump anyways, just lets us know she wants up, even though she could get up herself if she wanted to. But jumping and different stuff CAN cause LP, so I think every Chi shouldn't be allowed to jump up on furniture, however low it may be.
