@Claudia thank you
From someone who has two big dogs pressure fittings do not work we have to constantly keep moving it back, and it’s even stripped the gloss off our frames. We’ve just moved so got to buy the wall fittings. At least if we move again the small holes will only need a bit of filler
We have a pressure fit gate up in the doorway to our kitchen as we don’t have a door. It’s been there 4 years and we’ve not had any problems. I know the top of the stairs is slightly different and more dangerous if it comes loose, but our girls both swing on it no issue. It came with some sticky back cups to put on the wall and then the pressure fit gate ends goes in those. They seem to help it stay in place and not slip around. Might be more renter friendly than screws 🤷🏻♀️
Pressure gates aren't the safets. The bottom of the gate can easily be knocked out and the pressure is lost due to frequent use. I've had a pressure gate and switched to a fixed wooden one and I can't complain.
