Composium construction

The unique IDEON steel rail system creates a robust, durable understructure that withstands even the toughest environments. Each component is locked in place using multiple 5/16th grade 5 hex bolts through the rails. Arms are anchored by a high-performance molded joint system providing lasting durability and stability.

Extra strength monofilament webbing creates excellent resilience, while high-density foam provides comfort and rebound in a low-profile cushion.
