The ObusForme back support system in a medium-back multi-tilter — every adjustment covered, including the ones most chairs leave to chance.

The 1241-3 builds on the same orthopedic S-curve inner support system as the ObusForme high-back — a backrest engineered to hold the natural S-curve of your spine through a full workday, not just when you first sit down. The medium back profile suits desks with lower overhead clearance or users who prefer less back coverage. Ten independent adjustments including seat depth, seat angle, back angle, and height- and width-adjustable arms mean it fits the person, not just the height range. ANSI/BIFMA e3-2019 Level 3 certified — the highest achievable sustainability standard. Made in Canada.
