Spine-Healthy Seating - Executive Executive chairs feature a wide range of options for lumbar supports, arm rest type, neck and head rests, seat padding, tilt and height mechanisms -- options that allow the user to personalize and maintain the perfect level of body support. In addition, certain chairs are designed to accommodate taller and/or heavier users, and these factors play important roles in choosing an ideal, comfortable chair. The various options found in an executive ergonomic chair ensure that the user can adapt to various situations. For example, arm rest adjustments and shapes can create smooth transitions between intensive desk seating and facilitating meetings not taking place at a table or desk.
