Open the Angle. Elevate
The ergonomic principle
Elevated Seating opens your hip angle to 115–125°. The Vision Chair supports you through its seat and backrest, with your feet on the floor.
Explore the support in 3DGuides the seat’s knee-pivot movement, keeping support beneath your thighs while the backrest moves with you.
A contoured seat supports your body, while the textured grip surface helps resist forward sliding as the seat tilts.
Support that moves with you as you change position.
Your working position is part of your everyday environment. It deserves to be designed around you.

The support makes the difference
| Support & adjustment | | |
|---|---|---|
| Body support | Seat and backrest, feet on the floor. No knee or shin pads. | Seat and shin pads, with pressure below the knees that can cause discomfort. |
| Backrest | Lumbar support from a height- and depth-adjustable backrest | Not fitted on this backless design |
| Headrest | Height and depth adjustment | Not fitted |
| Armrests | 4D: height, width, depth and swivel | Not fitted |
| Movement | Full recline with backrest support | Rocking runners |
| Base & mobility | Smooth 5-caster base for easy rolling on any floor | No casters on this rocking frame |
| Tension and lock | Adjustable backrest resistance and upright backrest lock | No tension or lock controls on this frame |
Lean into a task. Settle into everyday sitting. Recline for a film.
Move between Elevated, Everyday and Reclined as work gives way to downtime.
Your work surface needs to meet your elevated sitting height.
A suitable desk riser with appropriate monitor adjustment can also work.
We recommend a height-adjustable desk to meet your elevated sitting height.
