A posture chair that does the work for you. The Varier ergonomic kneeling chair improves posture without conscious effort — the original design since 1979. Designed by Peter Opsvik in Norway, the Thatsit Balans and the Variable Balans are the two posture chairs in the Varier line that directly answer the “improve my posture” search. This page sits alongside the broader ergonomic kneeling chair hub.
What “posture chair” actually means
A posture chair is a chair that helps the spine settle into healthier alignment. Some posture chairs use lumbar shaping; some use straps or harnesses; some use seat-tilt geometry. Varier’s posture chairs use the seat-tilt approach — forward seat, open hip angle, no slumped position to fall into. The chair changes the geometry so the spine settles in alignment without conscious effort.
The Varier products that fit “posture chair” searches
- Variable Balans — the entry-level posture chair. Open hip angle, no backrest, the canonical 1979 design.
- Thatsit Balans — adjustable backrest, taller frame; for tall users or buyers who want backrest support during long sittings.
- Variable Plus — the Variable platform with a backrest as a fallback rest position.
- Wing — wider seat with contoured back.
For most posture-led searches, the Thatsit Balans is the chair to consider — its adjustable backrest gives feedback during the adaptation period.
Heritage and origin
1979. Designed by Peter Opsvik. Made in Norway. Continuously produced. The Variable Balans is the chair that defined the kneeling-as-posture-chair category; the Thatsit and Wing extended the same posture-improvement approach. “Posture chair” is descriptive of the design; the Variable line has been answering it for nearly half a century.
Frequently asked questions
Will the Variable improve my posture quickly?
The geometry change is immediate. Visible posture changes typically follow within the first few weeks of regular use, framed descriptively.
Are posture chairs the same as ergonomic chairs?
Overlapping but not identical. Ergonomic is broader; posture chairs are the subset specifically focused on spinal alignment.
Do I need to think about my posture on a Variable?
Less than on a task chair. The geometry settles the spine into alignment without conscious help.
Is the Thatsit better for posture than the Variable?
Same alignment principle. The Thatsit’s backrest gives more feedback during the adaptation period; the Variable’s no-backrest discipline tends to produce stronger long-term posture habits.
What about posture-correction harnesses?
Different mechanism. Harnesses cue you to sit up; the Variable’s geometry sets the alignment so cueing is unnecessary.
