I have a 12 month old baby boy and he is walking everywhere. We had this odd length opening going from the living room to the kitchen and we needed something to keep our lil boy from going through. This was perfect. I love this gate.. In fact, my husband and I were thinking about purchasing another one. It fits perfect. It came with three extra extensions so it worked out very well. We did not use one but we will keep it for if we ever move. Also love how it opens. Great so you dont have to step over or take down. Very simple to install.
