Will a new ergonomic chair feel different after a few weeks of use?

Yes — high-density foam (1.8–2.2 lb/cu.ft) feels noticeably firmer for the first 40–80 hours of use while the material compresses to your body weight and sitting pattern, so initial firmness is actually a quality indicator, not a flaw. Most users find their chair reaches its comfortable working feel within three to four weeks of regular daily use. Use that break-in window to fine-tune your lumbar height and seat depth as the cushion settles. Shop ergonomic seating at FindOfficeFurniture.com or call 888-719-4960.
