Developed through long-term use in Swedish care environments and tested to meet European laboratory and radiation safety standards, S1 delivers controlled, full-spectrum sunlight into daily care. Bright therapeutic light supports alertness and counters seasonal low mood (SAD). Infrared heat supports relief for muscle and joint discomfort, while safe, filtered UV activates natural vitamin D production. Together, these effects support calmer routines and a more stable care environment for residents and staff.
S1 is designed for reliable use in elderly care, dementia care, rehabilitation and sensory rooms. The system delivers:
Supports the body’s natural vitamin D production and immune function.
Short sessions are easy to integrate into established care routines.
Used daily in 350+ care homes
across Sweden.
Supports the body’s natural vitamin D production and immune function.

A Sunwell sensory room goes beyond installing S1 alone. In addition to light and warmth, we design complete environments where scenery, surfaces and atmosphere work together to create a coherent experience. By shaping the entire space, we engage sight, sound and sensation, strengthening the positive effects of the Sunwell Simulator.
Each sensory room becomes a place residents can go to feel calm, recognise familiar impressions and take a break from everyday surroundings. The environments are designed to support presence, orientation and recovery, while remaining safe, controlled and suitable for regular use in care settings.
The sensory rooms are a safe place to rest, engage and participate, supporting:
