Models of Hybrid Springs for Ergonomic Seats and Mattresses

An ergonomic seat or mattress has to provide optimal and uniform support for the body of a man or a woman with similar or slightly differing size centiles. It is a common opinion that spring systems in upholstered furniture are much more durable and more user-friendly than foam systems. The aim of t...

The aim of this study was to develop a new construction of an upholstery spring of bilinear stiffness.
