Ergonomic neck support: Asana GRID™ works like an effective orthopedic pillow for the cervical spine because it supports the natural positioning of the head relative to the torso. This can help reduce strain in the neck and upper back, especially when sleeping on your side or on your back.
-
GRID™ technology comfort: The additional ONSEN® GRID™ layer creates a flexible structure that adapts to pressure point by point. In practice, this means a softer first feel without losing the stable support needed for proper neck alignment.
-
More airflow during sleep: The open GRID™ structure supports free air circulation, so the Asana GRID™ pillow helps reduce overheating and maintain a pleasant sleep microclimate. This matters for people who dislike feeling stuffy or sweating excessively.
-
Stability without memory foam: The pillow is made from breathable high-resilience HR foam rather than memory foam. As a result, it does not sink excessively under the weight of the head, it returns to its original shape faster, and it provides more stable support throughout the night.
Asana GRID™ is an advanced orthopedic pillow that delivers a cloud-like comfort feel and precise support for side or back sleeping
Discover a new generation of sleep from the Polish manufacturer ONSEN®. Asana GRID™ is an innovative orthopedic pillow for back and side sleeping that combines anatomical support with a uniquely soft sensation. A modern layer of thermoplastic polymer in a hexagonal structure can create a cloud-like feel while still providing stable, healthy cervical spine support throughout the night. Our solution removes the usual trade-off between softness and ergonomics, so the Asana GRID™ pillow adapts point by point to reduce pressure, yet it does not sink in like viscoelastic foams.
GRID™ is an open, spatial hexagon-shaped structure that promotes intense airflow. This means Asana GRID™ can work like a cooling pillow, effectively reducing overheating and sweating during sleep. In practice, this means:
- constant airflow around the head and neck;
- wicks away excess heat and moisture;
- a fresh, hygienic sleep environment all night long.
The core of the Asana GRID™ sleeping pillow is contoured high-resilience foam, cast in 3D molds. Combined with the GRID™ layer made from modern thermoplastic polymer, it creates a system that:
- maintains the natural curve of the cervical spine;
- stabilizes head position for both back and side sleeping;
- makes changing positions easier without that sinking feeling.
The Asana GRID™ orthopedic pillow is a hybrid solution that uses:
- the dynamic resilience of high-resilience (HR) foam;
- the flexibility and point-by-point adaptation of thermoplastic elastomer (TPE);
- a unique structure designed for ventilation.
The Asana GRID™ orthopedic pillow is made in Poland and developed using:
- evidence-based design;
- design thinking methodology;
- a jobs-to-be-done approach (focused on real user needs).
By choosing our Asana GRID™ pillow, you invest in:
- modern sleep technology;
- uncommon ergonomics;
- durability and quality craftsmanship.
