Two calculators, built for the questions we get asked most and answered here without a product recommendation attached.
Both run in your browser. Nothing you type is sent anywhere or saved.
Desk and chair height calculator
Enter your height and it gives you seat height, desk height, screen height and the clearance you need under the desk, worked from published body-segment proportions. Most desk pain is a height problem, and most people have never measured the desk they sit at every day.
Heat or cold
Four questions about what happened and what it feels like, and a straight answer with how long to apply it. It also lists the signs that mean neither one is the right call and you should have it looked at instead.
What these will not do
Neither tool diagnoses anything. If something is not improving, or it woke you up, or you cannot put weight on it, the answer is a physiotherapist or a doctor rather than a purchase. Read our health disclaimer before using either.
