Most users report noticeable reduction in morning stiffness within 3-7 nights, with 87% experiencing significant relief from neck pain within two weeks. Your body may need a short adjustment period as it realigns after years of improper support.

The key is finding your ideal support level through our adjustable fill system, which allows you to personalize the pillow to your exact anatomy and sleeping preferences.

Yes. Circadian's unique combination of adjustable fill level and naturally responsive buckwheat hulls creates a pillow that adapts to any sleeping position. Unlike static foam pillows, buckwheat hulls microadjust hundreds of times throughout the night, flowing where support is needed while maintaining consistent height.

This dynamic response accommodates the 28 position changes the average person makes while sleeping, providing continuous support whether you sleep on your back, side, or stomach.

Unlike solid foam that traps body heat, Circadian's natural buckwheat foundation creates thousands of tiny air channels that continuously dissipate heat. Combined with our ventilated latex layer, this creates constant airflow that maintains consistent temperature throughout the night.

The natural properties of these materials create a significant cooling effect compared to synthetic alternatives, helping facilitate the 2°F temperature drop your brain needs to trigger deep sleep.

Your Circadian arrives calibrated to a medium support level that works for most sleepers. Fine-tune it by simply unzipping the inner chamber to add or remove buckwheat hulls using the included organic cotton storage pouch.

For personalized comfort:

• Add fill until your ear aligns perfectly with your shoulder when side sleeping
• Find the height where your chin remains parallel to the mattress when back sleeping
• Reduce fill until your neck feels naturally extended without strain when stomach sleeping

Trust your body's feedback—the right amount of fill is when you wake without stiffness and feel properly supported throughout the night.

Circadian combines the benefits of all pillow types while eliminating their flaws. Unlike memory foam that traps heat and resists movement, Circadian stays naturally cool and adapts instantly to position changes. Unlike down pillows that collapse under weight, Circadian provides consistent support all night.

Our patent-pending design integrates the natural temperature regulation of buckwheat with the comfort of ventilated latex through precisely engineered perforation patterns—a combination that took 37 prototypes to perfect.

Circadian is designed for simple care:

1. The entire cotton twill outer cover with the sewn-in latex layer is machine washable on gentle cycle with cold water
2. The buckwheat hulls naturally resist bacteria and odors due to their antimicrobial properties
3. For refreshing, place the buckwheat hulls in direct sunlight for 1-2 hours once a year

This minimal maintenance keeps your pillow performing optimally throughout its lifespan, unlike synthetic pillows that require frequent washing which accelerates their deterioration.

Circadian is designed as a long-term investment in your sleep. While conventional pillows begin losing support after 6 months, Circadian maintains its structural integrity for years.

The difference lies in our materials—buckwheat hulls become smoother and more responsive with use rather than breaking down. Our premium cotton twill develops a patina like fine denim, becoming softer while maintaining strength. This means your pillow actually improves with age instead of requiring replacement.

Most users report their Circadian maintains optimal performance for 3+ years—eliminating the cycle of disappointment and replacement that comes with conventional pillows.

Sleep transforms when you find the perfect pillow, but that discovery takes time. That's why we give you 60 full nights to experience Circadian in your own bed, with your own pajamas, and your own sleep routines.

If Circadian isn't revolutionizing your sleep, simply contact us for a prepaid return label. Once we receive it, we'll immediately refund your full purchase price.

We created this policy because we understand that despite our 2% return rate, comfort is deeply personal. The best pillow is the one that works for you, and we respect that.
