The Variable Balans is the original backless ergonomic office chair — no backrest, no slump, just an open hip angle and an active spine. Designed by Peter Opsvik in 1979, made in Norway ever since. This page is for the buyer searching specifically for a backless ergonomic chair; the answer is the Variable Balans ergonomic kneeling chair. This page sits alongside the broader ergonomic kneeling chair hub.
What “backless ergonomic office chair” actually means
“Backless” is the entire feature. A conventional office chair adds backrest, lumbar support, and recline; the Variable removes them. The hypothesis: a backrest invites slumping, lumbar pillows treat a symptom, and the most ergonomic posture is one that holds itself through geometry rather than support. The Variable’s seat-tilt and shin-pad geometry sets that posture without a backrest. The phrase “office chair” in the search is less accurate — the Variable reads as furniture, not office equipment — but the geometry is exactly what backless searches are looking for.
The Varier backless ergonomic chair
- Variable Balans — the canonical backless ergonomic kneeling chair from 1979.
The Variable is the chair that fits the search. The Variable Plus, Thatsit, and Wing all add a backrest in some form; if you specifically want a backless chair, the Variable is the answer. Visit the Variable Balans page for current configurations.
Heritage and origin
1979. Designed by Peter Opsvik. Made in Norway. The Variable’s no-backrest discipline is part of the original design intent — the chair was never meant to have a backrest, and the geometry is tuned around that absence.
Frequently asked questions
Is a backless chair really better than a chair with a backrest?
For active-sitting purposes, the no-backrest discipline keeps the spine upright by default. For a long meeting day, a backrest can be useful — the Variable Plus adds one to the same platform.
Does it tire your back to sit without a backrest?
Initially, possibly — your back muscles adjust over the first week or two. After that, the upright posture feels easier than slumping into a backrest.
Why is “office chair” the search term if Varier reads as furniture?
The phrase is what most buyers type. The chair sits in a home office without reading as office equipment.
Are there other backless Varier options?
The Move stool is also backless but in stool format; the Variable is the only backless kneeling chair in the line.
What if I want backless but with adjustable height?
The Move stool is the answer — backless, adjustable, designed for sit-stand desks.
