Your Office Chair Is Hurting You

But also, forget standing desks. Try ‘active sitting,’ according to a trauma surgeon who wants to cure sitting disease. -Ashley Abramson

Goodbye, Back Pain? This Office Chair Was Designed by a Trauma Surgeon

For decades, American workers have tried trendy office chairs hoping to alleviate the agony of sitting. Is the new ‘Active Stool’ the one? -Magdalena Puniewska

Improve Posture

“I love this chair. It keeps me upright, no slouching.”

Posture is your body’s response to gravity. QOR360 chairs are designed to allow your hips and spine to tip, gently aligning into a natural, comfortable position.

Relieve Back Pain

“I really can’t express how much this is relieving my lower back pain. I honestly can’t wait to get to the office and sit down!”

Active sitting keeps your core strengthened and body aligned. We are designed to move, and when you stay in motion, your back appreciates it.

“Sitting is the new smoking. (Really).”

“Nothing comes close to the QOR360 Ariel for me.”

Research shows that sitting is incredibly bad for our health. People sit more than ever (Americans, on average, sit for 11 hours per day!) and it’s literally killing us. Active sitting keeps your body in motion, and helps prevent sitting disease.
