How To Adjust the Ultimate Executive Office Chairs

These chair adjustments are aimed at promoting comfort and support during prolonged sitting and to alleviate pain.

Add More Comfort & Get Pain Relief

Every person is unique so a “one size fits all” option shouldn’t really be an option at all. The LIFEFORM® modular design allows people of all different shapes and sizes to create an ergonomic chair so they can sit comfortably. Whether you need support for an existing condition, a past trauma, prevent injury or simply want to find a chair that fits you right – small and narrow or you’re big & tall. We can help you get the best fit, unique to you.

Deep Seat

Overall, the Deep Seat option is an excellent choice for those who value comfort, posture, and accessibility. With its extra depth and width, this seat option can provide a more comfortable and supportive sitting experience, while also offering a range of health benefits. A wider and deeper seat option. Pronounced contouring (24”W x 20”D). Available only with Memory Foam.

Coccyx (Rear Seat) Cut Out

Consider choosing a chair with a coccyx rear seat cutout to relieve pressure and pain on your tailbone, especially if you experience sciatic pain or have a bulging disc in your lower back. The coccyx cutout provide multiple benefits, including alleviating pressure on the tailbone, improving posture, and providing additional support, which can reduce discomfort, pain, and stiffness in the lower back and hips.

Core-Flex® Dual Flex Seat

Increased circulation by incorporating a small range of natural motion into a chair so core muscles are stimulated allows for improved comfort. Research also shows that movement is also important for thinking and creativity, spinal fitness, and the maintenance of a healthy metabolism. *Not combinable with Coccyx (rear seat) cut out
