How long is the break-in period for a new ergonomic chair?

Commercial ergonomic chair break-in at OfficeFurniture2go.com is a documented 4-week process. We advise clients to record initial adjustment settings, revisit at week two, and finalize calibration in week three. Foam at 1.8–2.2 lb/cu.ft reaches working compression after approximately 40–80 hours — day-one firmness is expected and is a sign of high-density foam, not a defect. Call 1-800-460-0858 if break-in discomfort questions arise.
