Swivel chair

 

 

 

 

 

Every type of seating faces challenges when used at a 24-hour workstation. When the Sedus mr. 24 swivel armchair was being developed, these requirements were taken into account. The result is a design that is characterised by perfect ergonomics, an outstanding finish and absolute robustness. 24 hours a day.

Works continuously and never needs a holiday. A candidate for employee of the year

Fit for permanent use, the seat and backrest upholstery of Sedus mr. 24 are generously dimensioned and designed for heavy duty use, while the adjustment controls are user-friendly and very long-lasting. Even for people weighing up to 200 kilograms, this chair is comfortable and ideal for use  during shift work. The Sedus Similar mechanism enables a large opening angle and smooth motion of the body. This in turn enables relaxed working, even when the sitter leans far back in the chair. Comfortable neck supports and optimally adaptable armrests round off the extensive comfort characteristics of the chair.

Special features of a 24-hour chair

Office chairs that are in continuous use must meet special requirements in order to provide the best possible comfort even after many hours of use. This includes the neck support, the backrest and the seat, because the body should receive the right support in every position and at all times. That's why the 24-hour chair from Sedus is very robust, has top quality components and is guaranteed to be ergonomic.
