I really like it for my little girl, a 5 1/2 lb YorkiePoo. She can zip up to the bed in a flash, that is great for this older mom to not have to get out of bed to lift her up when she simply must get up! She often remembers she left a chew bone on the floor in the living room and she really, really needs to go back to get it for bed! My only complaint is the degree of slant is much too short for her to go back down. She cannot get her feet to the next step going down before she is tumbling down head first, because the next steps are steep with a narrow portion of the next step down not giving enough room for the back of her body to get on. I hope I am making sense, she is afraid after several tumbles all the way down. It is worrisome because to get down, she has to make a big leap off the bed. It is a big jump for a little one to make, I constantly worry that she will fracture something. That is my one and only complaint, I do like the stairs, I would buy it again, hoping one day we might find that problem resolved. It was very easy for this senior to put together and Daisy liked it from the first.
