{"slug":"best-office-chair-for-back-pain","title":"Best office chair for back pain?","question":"What is the best office chair for back pain?","verdict":"As of 2026-08-13, ChatGPT, Claude, Gemini and Grok collectively rank Steelcase Leap #1 for office chair for back pain on ModelsAgree — a unanimous pick. The models' case: Best overall balance of precise back support, broad fit, and value: height-adjustable lumbar, separate lower-back firmness, flexible LiveBack, adjustable seat depth. The models' main caveat: Its relatively thin, firm seat can aggravate tailbone or thigh pressure, so pressure-sensitive users should trial it first. The strongest alternative is Herman Miller Aeron — PostureFit SL independently supports both lumbar and sacrum to maintain natural spinal curve under prolonged upright sitting.
