Seating Design and Testing

Surface pressure profile of a person sitting using the Tactilus® Body Mapping Sensor System

Request a Demo


The NEW Tactilus® Bodyfitter® seat sensor system delivers real-time surface pressure distribution between a person and their seating surface.

Bringing human factors engineering to a new level, Bodyfitter® is capable of characterizing pressure magnitude of the seat surface, back rest and head rest simultaneously.

Bodyfitter® then assimiliates the data collected into our powerful Windows® based software providing you with everything from pressure maps to detailed statistical analysis. In the design of seating surfaces, position, density and conformity of materials is critical.

Bodyfitter® not only significantly reduces the number of test iterations required but is a evolutionary design aid towards the quest for ergonomic fit. Tactilus® Bodyfitter® is the most economical, scientific and user-friendly system for surface pressure mapping available today, both in the lab as well as in-store.

Tactilus® is matrix based tactile surface sensor that works by the principle of piezoresistance. Tiny sensing cells cover the entire surface area of our sensor "skin" allowing for discrete spot pressure analysis at any point in the contact region. Sensor Products primary proposition is to offer our clients precisely what they require or need. To that end, every thing we design can be completely tailored to your unique situation.
