Problem
Wheelchair users are at high risk of pressure injuries due to prolonged sitting, uneven weight distribution, friction, shear forces, and poor microclimate control, which can lead to discomfort, reduced mobility, and health complications.
Solution
TARKKA’s Tetrx™ custom wheelchair seating system addresses these issues through a fully personalized, 100% custom‑contoured seat that optimizes postural alignment and evenly distributes pressure. The seat combines a lightweight carbon‑fiber frame with an advanced latticed surface that enhances breathability and microclimate regulation. By simultaneously managing pressure, friction/shear, and temperature/moisture, Tetrx™ proactively prevents skin breakdown while improving overall comfort. The design also supports functional activities, enabling users to work, socialize, and pursue hobbies with greater confidence and reduced risk of sores. Tetrx™ transforms wheelchair seating from a basic necessity into a tailored solution that promotes health, comfort, and daily functionality.
Target Audience
Primary customers are wheelchair users who require long‑term seating solutions, including individuals with spinal cord injuries, neuro‑degenerative conditions, or other mobility impairments, as well as clinicians and rehabilitation specialists prescribing custom seating.
