The 4 Axes of Sleep

Unlike personality tests built for waking life, eSleep Clinic measures the 4 dimensions that actually decide your night.

Q vs R

Quick vs Reflective

How long does it take you to fall asleep after lights-off? Lightning-fast or 30-minute thinker?

M vs N

Morning vs Night

When is your peak cognitive energy — sunrise or after midnight? This determines your ideal bedtime.

S vs W

Silent vs Warm

Cool & quiet bedroom or warm & cozy bundle? Your environment sensitivity sets your bedding.

F vs C

Face-up vs Curled

Sleep on your back or curled on your side? This shapes the right pillow height & body support.

The 16 Sleep Types

Each combination of the 4 axes produces a unique sleep personality with its own catchphrase, spirit animal, and ideal bedroom setup. The rarest types appear in less than 3% of the population.

Why eSleep Clinic Is Different

"Most sleep apps ask how much you sleep. We ask how you sleep — and that changes the recommendations entirely."

Built on 4 dimensions: 24 weighted questions yield 13-step precision scores on each of 4 axes. The result: not just "owl vs lark" but a unique 4-letter type code with personalized bedding recommendations.

Personalized to you: See your sleep type, daily ritual, 7-day starter program, ideal bedding set, and the science behind why this combination works for your nervous system.
