We are using this gate at the bottom of our staircase and it works great. We purchased the bannister adaptors for the side and it fits snuggly. Just make sure you measure your opening as this and other gates have specific sizes for the gate itself as well as the included extensions. The dog respects the gate and stays downstairs when needed. We would highly recommend this gate to others.

I knew these gates were perfect before I bought them as I was able to use them at a friends house who also has a 1 year old like me. I bought them for the stairs, 1 at the top, 1 at the bottom. I wanted something I knew was secure for the staircase but convenient since people would be passing through frequently, and without having to step over them. You don't have to screw the mounts into the walls because there's a double sided adhesive that you attach at the pressure mounted ends. Plus I have an old house with original wood work and trim so I can adjust the tops differently than the bottoms to account for the trim without sacrificing a secure hold. They are perfect and keep my son from crawling up or falling down the stairs.

The if you need one extension for each side, beware. The wider the opening the harder it is to get the gate to close properly and the less sturdy it is. The gate itself is challenging to open. My six year old can't do it by herself.
