Does that block the top doorway then BB? The stands are quite large on the Wobust. I agree about not changing it for now. A couple of cable ties could help stop the rattle - eg if you now can't use the top door use a cable tie on that maybe. Having not actually seen a Barney, I wasn't sure if the Wobust stand would fit without blocking the top door so had planned to get this instead - although they're not cheap! About £15 and postage is £7.
