Top five stair gates for 2021

The key purpose of a stair gate is to keep your curious toddler away from anything that might cause them harm, including flights of stairs and busy kitchens with hot pots and pans.
All the stair gates have to meet the requirements of the relevant safety standard to pass our testing, which ensures they're sturdy, and can withstand the various shakes and rattles of a determined child.
However, the very best stair gates won't just be secure and safe. They'll have simple instructions for a straightforward installation, and they'll be easy to open and close.
These five stair gates got the highest scores in our tests, and are all Best Buys, so you can be sure they're a good option when it's time to pick out your safety gate. We've also included three stair gates to avoid. These gates failed a key safety test, which could put your child at risk, so we've made them Don't Buys.
