Bought one of these gates to put across the doorway to my garage to keep my dogs out. Loved it so much I bought another to put across a hallway to keep the dogs at one end of the house. I elevated the 2nd gate a bit so the cat can crawl underneath. It lays flat against the wall when open and works GREAT! There is no bottom strip to trip over and the lock can be modified to make it easier to open with one hand. Best gates I've ever used with a lifetime of dogs. Suppose it would work for two-legged babies too.
