We have a Svan baby bouncer, made of curved maple wood with satin walls and seat. It's very pretty. The baby can't bounce it herself, despite being a 15 pound lardarse. I used to bounce it from the front, although the instructions say to bounce from the base, because if I'm sitting on the floor with her, it's impossible to reach round and bounce from the base, and easier to push from the front, which a 22 pound baby (max weight) would more or less be able to do, weight-wise. But perhaps I was a little rough. But I don't think I was very rough, I was actively avoiding giving my baby whiplash. I was just bouncing it. From the front.
Anyway, the maple cracked and it's in pieces. British law (sale of goods act) says goods should be suitable for the purpose they were manufactured for, and I don't think I'd have any qualms about walking into a British shop and asking them what the hey? But I'm in Canada and don't know the law so well. Law aside, would you take it back? It was pretty expensive, about £85. I did not operate as specified. But I just pushed it back into the bounce. So I don't know.
