Product Features

Slouch-Proof
Unlike regular chairs that allow you to lean back at unsafe angles, ours was designed to fit the curve of your spine perfectly. This design cradles your pelvis and lower back, causing your vertebrae to stack into ideal posture. Sit back, and you’ll find it’s impossible to slouch. The result? Relief in your neck and shoulders and a difference you can feel.

Made to Move
Our Sit In Motion® technology makes this the only chair in the world that allows natural movement of the pelvis and back. It was built to move and rock with you, stimulating circulation, improving flexibility, and bringing more oxygen to your muscles.


Easy on the Eyes
Foldaway arms allow you to move much closer to your desk and reduce eye strain. Plus, our commitment to making things that last means we source materials carefully to create chairs that look sleek and at home in your space.

60-Day Money Back Guarantee
We know you'll absolutely love your chair, but if for some reason it isn't right for you, we’ll refund you the cost of the chair within 60 days of purchasing. Our chairs also come with a Limited Lifetime Warranty on all components with a one year warranty on cushions. For more details about our warranty click here.
