Independent Sleep Study Shows Twilla Users Sleep Better and Recover Faster

In a world where quality sleep is more valuable than ever, we believe results should speak louder than promises. That’s why we partnered with real people and independent technology to put the Twilla Orthopedic Pillow to the test. The results? Look forward to better sleep.

The Study at a Glance

Over a 28-day period, 20 adults ranging in age from 24 to 75 tracked their sleep using the WHOOP Health & Sleep Tracker—a leading tool used by athletes, professionals, and sleep scientists alike. Participants spent between 14 to 21 nights sleeping on the Twilla Orthopedic Pillow, and 7 to 14 nights using a different (non-Twilla) pillow.

The focus? Measuring the difference in Sleep Scores and Recovery Scores—two key indicators of sleep quality and physiological recovery.

Sleep Scores: 

The WHOOP Sleep Performance Score measures overall sleep quality based on:

• Sleep Sufficiency (hours slept vs. hours needed)

• Sleep Consistency

• Sleep Efficiency

• Sleep Stress

Twilla users averaged an 89% sleep score, compared to just 78% with other pillows—a 12% improvement in overall sleep performance.

Recovery Scores: 

WHOOP’s Recovery Score reflects how well your body has recovered overnight—factoring in heart rate variability (HRV), resting heart rate (RHR), and sleep quality.

Twilla users averaged a 76% recovery score, while the average recovery score on other pillows was only 63%—that’s a 17% improvement in nightly recovery.

Why We Trust the Data

Unlike generic surveys or subjective feedback, this study used objective, biometric data from WHOOP, a trusted health performance tracker. That means the results weren’t based on how users felt—they were based on measurable physiological improvement.

Sleep Better. Recover Faster. Live Healthier.

At Twilla, we’re committed to making sleep better for everyone. If you’re looking for a pillow that actively supports your body’s ability to heal and recharge—Twilla isn’t just a better pillow, it’s a smarter one.
