The Big & Tall executive task chairs are the culmination of years of design, research and testing in the fields of anthropometry, ergonomics and bariatrics by Certified Professional Ergonomists (CPEs). Some competitors simply place a larger seat and backrest on a common chair control and then roll the dice on warranty coverage. Neutral Posture delivers solutions without compromising strength, durability or appearance. Available with or without our unique, adjustable neckrest.
