Frequently Asked Questions
Are pressure-mounted gates safe at the top of stairs?
For the top of stairs, hardware-mounted gates anchored into the wall or studs are the safest option. Pressure-mounted gates are convenient and fine for ground-floor doorways and hallways, but manufacturers and child-safety experts recommend hard-mounting when preventing falls is the main goal.
How do I measure to make sure a gate fits?
Measure the clear opening between the surfaces where the gate will mount (exclude baseboard or trim). Compare that number to the gate’s adjustable width range — choose a gate that covers the measured width without exceeding the limits. If using a pressure mount, also check manufacturer notes on uneven surfaces.
Can a potty-training seat replace a gate for bathroom safety?
No — potty-training seats support independence at the toilet and may help children reach sinks, but they don’t block doors or hallways. Use a gate to control access and a potty trainer to adapt bathroom height needs as kids grow.
