How we choose

Start with the situation

Each guide is built around a specific use: a body shape, a room, a journey, a garden. Before looking at any product we write down what actually decides success in that situation, such as dimensions, adjustment, noise, weight, weather resistance or a rule set by an airline.

Research, not guesswork

We compare manufacturer specifications, sizing charts and published guidance, and read independent reviews from established testers where they exist. Where a policy matters, such as an airline's cabin bag limits, we link to the official source so you can check it yourself.

Honest about what we haven't tested

Our guides are desk researched. We do not claim hands-on testing unless we have done it, and we never make up scores, measurements or reviews. Where a recommendation is a type of product rather than a single model, we say so.

Kept up to date

Products change, get discontinued or move price. Every guide shows when it was last updated, and we revisit them regularly. If you spot something out of date, we would like to hear about it.
