Jack Dell'Accio

CEO & Founder of Essentia | Certified Sleep Coach


Jack Dell’Accio is the CEO & Founder of Essentia and a certified Sleep Coach who has spent over 21 years dedicated to understanding, measuring, and improving the quality of human sleep. His work centers on one core belief: restorative sleep, specifically REM and Deep Sleep, is the foundation of long-term health, disease prevention, recovery, and peak performance.

Rather than focusing on sleep as a passive activity, Jack approaches it as an active, measurable biological process, one that can be optimized through better environments, cleaner materials, and intentional design. This philosophy led him to create Essentia, the world’s only line of organic mattresses engineered specifically to enhance restorative sleep cycles.

Expertise & Experience

Jack’s expertise has led him to work closely with elite athletes across major professional sports leagues, including the NBA, NFL, MLS, and more than 25% of active NHL players. By optimizing sleep quality, he helps athletes accelerate recovery, improve resilience, and sustain high performance throughout demanding seasons.

Under his leadership, Essentia has earned recognition from respected institutions, including the Mayo Clinic’s Well Living Lab, and has been ranked the #1 foam mattress by Consumer Reports for over eight consecutive years, an unprecedented achievement in the category.

Research & Innovation

Jack has also led a landmark double-blind sleep study with professional athletes, demonstrating that sleeping on an Essentia mattress can increase time spent in REM and Deep Sleep by 20% to 60%. These findings reinforced his long-held belief that the right sleep surface, free from harmful chemicals and designed to support the body’s natural physiology, can meaningfully change sleep outcomes.

This research continues to inform Essentia’s patented technologies, including its Beyond Latex™ Organic Foam and performance-driven sleep systems.

Philosophy

At the heart of Jack’s work is a commitment to removing barriers to restorative sleep, whether chemical, environmental, or structural. He believes that organic materials, proper spinal alignment, pressure relief, and EMF-conscious design are not luxuries, but necessities for anyone serious about health, longevity, and performance.

Through Essentia’s educational content, research initiatives, and product innovation, Jack continues to challenge conventional thinking around mattresses and sleep, advocating for solutions that are both scientifically validated and genuinely restorative.
