Opera 20-8-W Ergonomic Office Chair Product Details

The Opera 20 chairs have the highest specification within the Opera chair range, with a smooth knee tilt rocking action, the chair instantly follows your body's movements - providing a natural feel when rocking. The rocking action offered on the Opera 20-8-W ergonomic office chairs stimulates blood flow to increase oxygen levels and avoids static seating.

The Opera 20-8-W chairs have a range of seat sizes, optional extras and our custom-fit service (see below), allowing us to tailor-make the Opera chairs for any requirement and individual. The Opera 20-8-W has a sewn edge seat and back as standard for maximum comfort and a polished aluminum star base for an executive look.

Custom-Fit Service

Our custom-Fit system enables us to create truly bespoke back rests on your Opera chair to provide unrivalled tailored support and comfort. We can visit any location in mainland UK or invite individuals to visit our showroom in Lancashire where we will measure and assess for the back rest required.

We use our specialised system to map our back rests with varying densities of foam and supports to create any shaped back rest required. Our Custom-Fit option is ideal for Scoliosis Spina Bifida, Spinal Surgery and various other conditions. Just select the Custom-Fit option above and we will contact you to arrange the assessment.

Heated Pads

The optional heated pads continuously stay on for approximately 30 minutes, after this time they will turn off automatically as a safety precaution. You can however simply turn them back on should you wish for the heat to continue.
