L.R.
Hi,
Sorry, I can't remember the name of the brand that we purchased for our stairway. We have two, one at the top and another at the bottom. My husband had to install them- they're wooden swinging gates. The latch is totally child-proof. In fact, at the beginning we had trouble getting used to opening and closing them. You can get them at any Babies R Us. I'd recommend this type of gate as opposed to the removable ones. There's another plastice one that has to be installed too, but there's a lip at the bottom. If you're not paying attention it's easy to trip over. The wooden ones are the best option...good luck!
