We have a very open plan main downstairs room with open backed stairs. In fact the whole of our lower floor is practically one room bar the loo. My DTs have just started to motor around using the sofa and have already scaled the temporary barricades we have made with the cushions from the arm chairs etc. I think we need a play pen of some description and I like the idea of it being a room divider too. Would one of the above (in pen mode) be big enough for two? Can you join two together if needs be? Can you snap it anywhere to have the door where you want it ? Which one is best ? Has anyone seen a super bargain on t'internet? Cheers.
