This gate is fabulous. Well worth the price. It is a walk through gate so you just open it like a door, go through and shut it again. It is also pressure mounted so it can be moved later. This was perfect for our house. We had one of those cheap $20 wood pressure mounted things that you have to use the stick lever and move the WHOLE gate to get through, or try to step over it. This gate is much better because the area to the stairs is also where the front and garage doors into the house are, as well as the dog bowls (all things we use several times a day and all things we need to keep her away from).
