The Anthros has a weight capacity of 300 lbs.
That's not just a label. The chair is independently tested by BIFMA (the industry's safety standards organization) to meet or exceed 300 lbs for structural integrity, long-term durability, and tipping resistance.
Why our foam holds up
Our cushion foam comes from the same supply chain as wheelchair seating — an environment where people sit for 12+ hours a day and foam failure has real health consequences. High-density foam resists compression over time in a way standard office chair foam simply doesn't.
One thing to check: spring selection
If you're over 150 lbs, choose the Standard Spring when configuring your chair. The Light Spring is for users under 150 lbs. This affects tilt tension, not safety — the wrong spring won't break anything, but the chair will feel too easy to recline.
