Our customized perches mimic the natural tilt of the pelvis and prompt upright, alert sitting. Great for home or office. Support yourself and our mission. Sitting in most standard chairs for extended periods is bad for your back, neck, core, legs, circulation, digestion, attention, and attitude. Sitting with your knees below your hips, and your feet firmly supported, helps align your spine and neck, which will relieve strain, promote circulation and facilitate abdominal breathing -the key to well-being.

"For modern researchers, many of the ideas proposed two decades ago by Danish surgeon, A.C. Mandal, M.D., regarding the spine began a major paradigm shift in the way we evaluate the seated worker. Many of theses ideas have been validated in more recent studies. Simply put, Mandal believed that the century-old concept of proper sitting -upright with a hip angle of 90˚- was wrong. This type of traditional sitting, still practiced today and considered by many to be the one proper way of sitting, is now know to decrease lordosis (the natural inward curvature) of the lumbar region of the spine, and increase kyphosis (an outward round of this region of the spine). This is exactly the opposite of what we need, in terms of a posturally healthy sitting - we should avoid kyphosis in the low back and maintain a moderate level of lordosis. For us, this would mean incorporating the natural curves of the spine into our seated posture, neither flattening nor exaggerating these curves."
