/ Biomechanical Cohort Data

Lateral sleep alignment verified

In continuous multi-week pressure sensor trials, ninety-six percent of dedicated lateral sleepers maintained neutral cervical angles without nocturnal pillow bunching or mid-sleep neck strain.

Shoulder Pocket Calibration

Loft depth by biotype

Narrow To Standard Frame

Four-inch shoulder clearance

For clavicle spans measuring fourteen to seventeen inches, the low-profile core maintains an uninterrupted neutral cervical plane while releasing acromion pressure entirely.

Broad Frame Calibration

Five-point-five inch lift

Wider eighteen to twenty-two inch shoulders receive the supplemental dense insert, preventing lateral head tilt and eliminating trapped brachial plexus nerve tingling by morning.

Verified Sleeper Feedback

Shoulder relief documented

My morning shoulder numbness vanished after night four. The cervical recess stops my head from canting downward during deep sleep.

David K., Broad Frame Sleeper

Zero ear cartilage pressure and no midnight repositioning. My cervical spine stays straight from bedtime until my morning alarm rings.

Elena R., Narrow Frame Sleeper

Standard memory foam forced my chin toward my sternum. Melara gives true horizontal shoulder clearance without foam collapse.
