As my kitchen is part of the living room I needed something to stop my toddler from coming into the area when the oven was hot so purchased the baby dan play pen to use as a sort of temporary wall. The gate on its own was very sturdy but as he got older he was able to move this as it wasn't fixed to anything. I purchased the wall kit and found it very simple to fix the gate to my wall, thus making it unmoveable by an 18 month old boy! It's also stood up well to a rather heavy handed daddy too!! :) The kit includes fixings for both ends so you'll only need to purchase one, I only actually have mine fixed at one end but the other's useful as a spare. My only negative point is that at the price of the playpen I'd have thought they could have included this as it does add even more to its already high price. That said it is worth it for the extra peace of mind
