Nychteri Structured Support, Composed Balance.
Defined by precision and adaptability, Nychteri represents a structured approach to rest — a mattress built to deliver stability, controlled support, and quiet luxury. Inspired by a full-bodied dry white wine from Santorini, it carries a sense of balance shaped over time, pairing responsive support systems with rare natural materials for a deeply restorative sleep experience.

Profile & Ergonomics A structured approach to comfort — stable, precise, and quietly powerful. Engineered with a responsive medium-to-firm feel, Nychteri adapts progressively to weight and pressure, minimizing unnecessary sinking while maintaining natural spinal alignment. The result is a sleep surface that delivers defined support without sacrificing comfort.

• Ideal Sleep Positions: Back Sleepers | Sleepers preferring firmer support | Those seeking stability and reduced pressure in the lower back.

Engineering & Core Construction At the core lies the DreamBalance™ system, a multi-layer dual-spring mechanism that responds progressively to pressure, activating additional support only where required.

• Targeted Support: Body-specific responsiveness that adjusts instantly to weight distribution and posture changes.

• Zero Motion Transfer: Isolates movement across the sleeping surface for undisturbed rest.

• Thermal Regulation: Continuous airflow channels throughout the structure prevent heat retention.
