Marva is a functional office swivel chair with many smart ergonomic features, whose soft rounded shape exudes a homely character. One stand-out feature is the new, extremely flat synchronous mechanism with automatic spring-loaded seat adjustment, which is invisibly integrated into the seat. This facilitates dynamic sitting, precise adjustment of the seat, backrest and lumbar area, and multiple armrest settings. The backrest is concave, shaped to enclose the body and fully covered with fabric. An eye-catching detail is the zip on the reverse of the backrest.
