The Reactive Lumbar Cell features three interconnected air chambers that respond dynamically as pressure is applied, providing adaptable support across the sacral, lumbar, and lower thoracic regions.
This system is particularly useful if you prefer a gentler, more accommodating lumbar support.
When inactive, the air-cell lies completely flat; when inflated, it reaches a depth of approximately 80–90 mm. Backrest air-cell options include a standard inflation bulb, with a battery pump available as an optional upgrade.
