- OPUS-C Coccyx Task Chair with Pressure Relief Seat
The Ergo-Postural Coccyx Task Chair features an upholstered coccyx cut-out within a Reflexion® seat cushion. It also includes advanced standard features such as inflatable lumbar support and seat depth adjustment.
The chair is suitable for users from 5' 4" to 6' 1".
OPUS chairs use an A/Synchro mechanism, allowing the seat and backrest angles to be adjusted independently. This makes the chairs both corrective and preventative, providing purposeful office seating with ergonomic, posture-active, and orthopaedic properties as standard.
Optional inflatable support panels are also available for the sacrum area below the lumbar region and for the thoracic area at the top of the backrest.
This Task Chair exceeds HSE seating-at-work directives and has been SATRA tested to BS5459 for 24-hour use.
The standard black base is suitable for most users. A stylish polished aluminium base is available as a paid upgrade and is recommended for users over 18 stone (114kg).
With more people working from home, it is important to know that not all office chairs sold in the UK meet domestic fire safety requirements. All our office seating complies with UK fire safety standards for both home and workplace use.

Chairs & Leg Rests
The production time for chairs varies depending on the model and quantity, and may take up to 15 working days from the date of your order. This period includes the manufacturing process for each chair, as well as the selection of options and upholstery colours.
After your chair/s are manufactured, we ship them via carrier or van using next-day delivery. For deliveries to mainland UK, this service is either free or costs £20.00 plus VAT, depending on the manufacturer. Additional charges apply for addresses in the Scottish Highlands & Islands, Channel Islands, Northern Ireland, and Isle of Man.
Chairs delivered by carrier are packaged in high-quality, sturdy boxes to eliminate any damage during transit. In the off chance there may have been damage in transit, please make sure you contact us within 2 days of delivery.
The chairs are packed carefully and securely, and as such, there is a small amount of self-assembly. These are not flat-packed, where you require tools. All components, such as arms, are already fitted with everything slotting together, so assembly is simple and speedy.
The PS06 and Xcel chairs and their variants may be delivered fully built, depending on location. Please check with us prior to ordering, and we will be able to advise on the delivery method for these models. Please contact us by either using the contact form → Here or calling on 01388 748 999. We are always happy to help.
