Sleep Position: What the Research Says
Body position during sleep is one of several factors researchers examine when looking at overnight physiology, comfort, and sleep quality. People shift through many positions in a night — supine (back), lateral (side), and prone (stomach). This page is an educational overview of what is currently understood. It is not a product pitch, not medical advice.
Komori is a general wellness device in development. It is not a medical device, not FDA-cleared, and not intended to diagnose, treat, prevent, or cure any condition. If you wake up sore, in pain, or with concerning sleep symptoms, please see a clinician — a primary-care provider, sleep clinician, or musculoskeletal specialist as appropriate.
How Komori Works
Sleep Comfortably
No wearables to irritate sensitive skin or disrupt sleep. The contactless sensor works through blankets above your bed.
Record Position Through Blankets
Komori is designed to record body position — back, side, stomach, and transitions — through blankets. No charging, no wearable to remember.
Review Your Own Data
Komori is designed so you can review a personal overview of position patterns and, if you choose, share the data with a healthcare provider. Komori is not a medical device and does not diagnose, treat, or prevent any condition.
What You'll Discover
Position Breakdown
Komori is designed to record body position over the course of a night for personal review — supine, lateral, prone, and transitions.
Movement Timeline
Komori is designed to surface a minute-by-minute timeline of movement and position shifts for personal review.
Personal Journal
Komori is designed to let you keep an optional journal — for example, morning stiffness notes — alongside overnight position data for personal review.
Bedroom Environment
Komori is designed to record temperature and humidity trends in the bedroom for personal review. Contactless and processed locally by default.
Bed-Exit Reminders
Komori is designed to send a notification when an extended bed exit is detected. Not a replacement for a medical alert system.
Exportable Personal Data
Komori is designed so you can export your own data and share it with a healthcare provider if you choose to.
A Brief Overview of Sleep Position
The information below is educational and is not a substitute for evaluation by a clinician.
Sleep position is one of several factors that researchers examine when looking at overnight physiology and subjective sleep quality. What an individual experiences personally is best understood with the help of a qualified clinician, not a consumer device.
Common Sleep Positions
Adults typically cycle through supine (back), lateral (side), and prone (stomach) positions. Most people change posture many times across the night — even when they don't remember it.
What Researchers Examine
Sleep-position research has touched on snoring and sleep-disordered breathing, reflux symptoms, comfort and musculoskeletal pain patterns, and autonomic-nervous-system measures. Findings vary across studies and across individuals.
Where to Learn More
The American Academy of Sleep Medicine (sleepeducation.org) and the National Sleep Foundation publish patient-facing educational materials on sleep, including general background on body position.
For diagnosis, treatment, or management of any condition — including chronic neck or back pain, snoring, sleep apnea, or reflux — speak with a qualified healthcare provider.

Position Breakdown
Night Timeline
Komori is designed to surface a personal overview of position, movement, and environmental patterns from the night. The data is for personal review and, optionally, for sharing with a healthcare provider. Komori is not a medical device and does not diagnose, treat, or prevent any condition.
Why Komori?
vs. Wrist Wearables
Wrist wearables (Apple Watch, Whoop, Fitbit) don't capture body position and can be uncomfortable for sleep.
vs. Smart Rings
Smart rings (Oura, Ultrahuman) focus on wrist-style metrics and don't capture sleep position.
vs. Under-Mattress Mats
Under-mattress mats (Withings, Emfit, Sleep Number) are typically single-person and don't capture body position.

This is personal.
My twin boys got sepsis in the NICU. One of them was infected three times — the only documented case. All I wanted was to know they were okay.
Those nights changed everything for me. I couldn't stop thinking about how helpless it felt to not know what was happening while someone you love is sleeping. That question — "are they okay right now?" — never really left me. It followed me through 20 years of building data systems, through designing Owlet's data pipeline, through leading technology at SAMi Alert. Every role taught me something, but the question was always the same.
I built Komori for families like mine. Families who lie awake wondering. Families searching for insights that lead to answers. You spend a third of your life asleep. The night has answers. But you can't act on what you can't see.
Komori opens that black box. 60GHz radar that sees through blankets. No camera. No wearable. No video. Just data nobody's been able to give you before.
I designed every system. Every algorithm. This isn't a side project. It's the reason I learned everything I know.
