The LogicBack custom posture support was designed and engineered to correct and support the lumbar, spine and pelvis by putting all of them into their perfect anatomical positions, allowing for the Effortless Neutral Posture. It provides support that most chairs sold on the market are missing by default: lumbar support. The LogicBack provides the perfect solution by customizing itself to each individual user’s unique lumbar, spine and pelvis shape. In addition, your pelvis can slide fully back into the chair while benefiting from this anatomically natural, and neutral position.

The patented adjust and lock system allows the LogicBack to accommodate any lumbar shape, by changing dynamically from person to person. Simply release the strap system and repeat the process for a new body shape. The LogicBack weighs only 21 oz. and is small enough to travel with.
