How do I use my sizing kit?
1. Choose your finger
Choose any finger where the ring fits snugly at the base. We recommend your index finger for optimal accuracy.
2. Find the best fit
Start with the smallest sizing ring that slides over your knuckle. Repeat on another finger to find the best fit.
3. Wear it for 24 hours
Finger size changes, especially overnight, so we recommend you wear your sizing ring for 24 hours.
4. Confirm your size
Confirm your size in the Happy Sleep app. We’ll ship your ring right away.
