How do I adjust an executive chair for proper ergonomic posture?

Start with seat height: thighs parallel to the floor, feet flat. Set lumbar support to fill the natural hollow of the lower back — it should support without pushing the spine forward. Adjust armrests so shoulders relax and elbows are near 90° while typing. Set tilt tension so reclining requires some effort — passive reclining under body weight alone is too loose. Set headrest to gently support the back of the head in a neutral position. At OfficeFurniture2go.com, our team walks customers through initial adjustment at delivery — call 1-800-460-0858.
