Can I use a pressure-mounted baby gate at the top of stairs?

The strong consensus across the reviewers we read is no. Specialist subreddits including r/NewDads (where a self-described professional childproofer weighs in) and r/beyondthebump repeatedly stress that the top of stairs requires a hardware-mounted gate screwed into wall studs. Pressure-mounted gates are recommended only for doorways and the bottom of stairs.
