+ Sculpted twin ischial positioning wells and coccyx void
The DUO™ 400 SKULPT TwinPoint™ evolves the proven DUO seating platform through a new sculptured ergonomic seat geometry designed around the relationship between the seat and pelvis .
At the centre of the SKULPT seat are two subtle TwinPoint™ ischial positioning wells, shaped into the seating surface to help naturally locate the pelvis in a balanced working position.
Pelvic Support Reimagined
An evolution of the DUO™ Dual Density Posture Support platform, DUO™ 400 SKULPT TwinPoint™ combines built-in firmer front / softer rear cushioning with sculptured seat geometry designed around the relationship between the seat, pelvis and lower lumbar backrest.
Two shallow, elongated TwinPoint™ ischial positioning wells help locate the sit bones within the softer rear seating area. Smooth transitions connect these contours with the surrounding pelvic and thigh support areas, while a coccyx void provides clearance around the tailbone.
DUO 400 — Tall Back / Deeper Seat
The tall backrest provides lumbar and spinal support with additional height to accommodate taller users, making the DUO 400 suited to general office and workstation use.

How the support works
.png)
Sitting on the softer rear cushion allows the pelvis to settle gently towards the back of the seat, between the firmer front cushion and the lower lumbar backrest.
.png)
These three elements work together to help locate and support the pelvis:
-
Softer rear cushioning allows the pelvis to settle into the rear seating area.
-
Firmer front cushioning helps define the pelvic seating position.
-
The lower lumbar backrest provides support behind the pelvis and lower back.
This relationship is intended to support the natural inward curve of the lower back and the spine’s overall S-shaped profile, helping the user find a supported alternative to a slumped, rounded sitting posture.
TwinPoint™ refines this relationship through two shallow, elongated positioning wells. These contours help locate the ischial tuberosities (sit bones) within the rear seating area without sharply defined edges.
The coccyx void provides clearance around the tailbone and is designed to reduce direct pressure in this area.
Position
The sculpted positioning wells help the user settle into a supported pelvic position towards the back of the seat, where the firmer front cushioning and lower lumbar backrest can work together.
Posture Support and Alignment
The seat supports body weight through the pelvis, providing a stable foundation for desk-based tasks. The built-in cushioning zones and adjustable chair settings work together to support the user’s seated position. Supporting the pelvis towards the back of the seat helps establish a foundation for the spine’s natural curves. Seat and backrest adjustments allow the user to refine that support to suit their body and working position.

Movement
A supported posture is a starting point for movement.
DUO SKULPT TwinPoint™ is designed to help the user find a balanced seated position, with adjustable settings to suit changing tasks. Regular changes of position and opportunities to move remain important throughout the working day.

Problem to Solve
When the pelvis slides forward / rolls backwards, the relationship between the seat, lumbar support and spine changes with it.
The DUO SKULPT TwinPoint™ approaches the problem through designed Seating Geometry.
Two shallow sculptured wells correspond with the primary ischial loading region, helping provide subtle positional feedback beneath the pelvis without creating hard edges or restrictive pockets.
The surrounding contours transition smoothly into the thigh-support area, while DUO’s firmer front cushioning provides a more stable forward platform.
S E A T™ — Primary
Support · Elevation · Angles · Tilt
DUO SKULPT TwinPoint™ is a direct application of S E A T™, bringing greater attention to the physical geometry of the sculpted seating surface itself.
It supports:
- pelvic location through TwinPoint™ geometry
- dual densisty posture support- soft rear / firmer front cushion
- distributed support around the ischial region
- coccyx void to reduce direct pressure in the tailbone area.
- controlled 0 - 9 Degree Forward Tilt
- adjustable seat height
- adjustable backrest positioning
