Luxurious Fabric Office Chair with Cushioned Padding
The densely padded backrest features stylish stitched detailing, while the contoured seat and headrest supports a comfortable posture all day long. A waterfall seat edge eases pressure on the thighs, improving circulation to the legs to prevent numbness or discomfort. The fabric upholstery feels soft to touch, but is incredibly durable and hard-wearing for long-lasting performance.High Back Office Chair with Lumbar Support and Headrest
The Logix 24 Hour High Back Office Chair has a tilt-adjustable headrest, offering additional support for the neck and head. It also features a height-adjustable backrest with an easy-to-use ratchet mechanism, letting you position the lumbar support exactly where you need it. An air bag within the backrest can be inflated using the hand pump beneath the seat – inflate it fully, then sit in the chair and press the deflate button until you find your preferred level of support.Support Your Spine with Synchronised Tilt
An advanced synchronised tilt mechanism moves the back recline and seat angle together in one dynamic movement, keeping the spine perfectly aligned in all sitting positions. Simply pull the lever up to unlock the mechanism and allow the chair to float freely. Push it down again to lock the chair into the required position. A hand wheel at the front of the chair adjusts the tilt tension to suit your body weight – turn clockwise to increase the tension and anti-clockwise to reduce it.Experience the Continuous Support of a 24 Hour Office Chair
Loaded with adjustable features, the chiropractor-approved ergonomics of the Logix 24 Hour High Back Office Chair allows each user to fine-tune their seating position at the start of each new shift. A quality gas lift ensures smooth seat height adjustments, while the seat slide feature finds the perfect depth for individual body heights. Find the optimum seating position to suit your size and desk setup, and work comfortably all day long – multi-directional armrests can also be adjusted to reduce the risk of repetitive strain injury (RSI).Built to Last with 5-Year Guarantee and FREE Next-Day Delivery

What is considered a high back office chair?
A high back office chair usually refers to a tall backrest that extends above the shoulders of the user while providing support to their lower, mid, and upper back. The extra support helps reduce neck and shoulder strain. An office chair with a high backrest usually includes complementary ergonomic features such as integrated lumbar support and adjustable armrests and headrests.
Are high-back chairs better for your back?
