Simple to use

“The aim was to create a highly functional product within the simplest form possible.”
With increasing pressure to create a highly functional office chair, the assumption would be that a more complex product would materialize. Yet complex forms and functions are not always appealing; in fact, more often the simplest design solutions turn out to be the truly successful products.
In that spirit, we decided that even if we have a complex mechanism at the heart of the chair, or extra functions, they would be as unobtrusive as possible.
In other words, we wanted an Ultra-Simple design.

The simple design complements a new innovative reclining mechanism, providing operation that anyone would find easy to use.
The Quick Slide lever will smoothly alter the reclining tension to provide the best support for the modern working lifestyle.

Simple to choose

The Choral chair with its dynamic styling is balanced to match many office environments, with an endless choice of variations to suit personal tastes in color, size and function.
The standardized design means the many variations have the same functional and styling concept; therefore creating harmony within office design.
The wide range gives employees and companies the flflexibility to fifind the ideal choice to suit their varying work styles.

Multiple Density Cushion

Multiple Density Molding technology realizes a seamless gradation molded cushion. The seat pads front area is soft, and the rear area is firm to increase hold to the user’s body. This 3D support distributes body weight evenly to reduce pressure points and so improves blood circulation for health sitting and superior comfort.

Ankle-Tilt Reclining

The synchronized Ankle-Tilt reclining mechanism reflects Okamura’s strong belief in ergonomically correct and user friendly products.
The reclining movement with the load distributed from the ankle provides a natural movement that also reduces pressure to the upper leg area.
Choral has a reclining angle up to 23°.

Headrest

The fully adjustable headrest has pivot and height movement enabling you to find the best possible position. Also, the sliding structure is completely internal, making it a simple add-on option.

Hanger

The hanger has a push-button lock that allows for 4 3/4″ (120mm) of height adjustment.
When not required, it can be neatly stored away behind the backrest.

Lumbar Support

The lumbar support is designed to give extra support and is flexible enough to suit a wide variety of body shapes.
The adjustment range is 2 3/4″ (70mm) vertically providing comfortable support to the natural “S” curve in the spinal area, which helps to reduce stress.
