## Description

Product Description               BackJoy Posture+Waterproof and durableSuitable for use inside and outdoorsComfortable closed-cell EVA foam paddingSuitable for 55-125kgFrom back pain to BackJoy.BackJoy's patented design encourages optimal posture and engages core muscles so you can sit more comfortably, and correctly, to get more out of life. BackJoy is not a simple cushion, it contains APS Technology and Advanced Core Materials. It was designed so you can automatically sit with optimal sitting posture, anytime, anywhere.You can sit on anything from the office chair or car seat to a rock hard surface with greater comfort, for longer.Here's how it works:1) Our patented Applied Postural Science (APS) corrects your posture. You know that you are supposed to sit better, but it's hard. Our APS Technology automatically tilts, cups, and floats your pelvis upright so you can find your most balanced and comfortable posture.2)BackJoy naturally maintains your posture while you sit. You move when you sit so Posture+ moves with you, freeing your pelvis to actively stabilize your spine. It automatically adapts to your movements to provide constant strain-free comfort and optimal posture; and you wont have to even think about it.3) BackJoy engages your core muscles. You know how important your core is, but when you sit your core is not engaged. BackJoy dynamically supports your pelvic floor to engage your core. With natural balance and support, you will feel comfortable, stronger and less fatigued after sitting for long periods of time.Don't be fooled, although a BackJoy sitting device is not very big in size, it is very powerful in its results. Its patented Applied Postural Science is based on years of research and is designed to be simple to use yet incredibly effective. It is dynamic and reacts to the way your body moves, allowing your spine to sit in proper alignment. Its three-part design tilts, cradles, and lifts your pelvis to create better posture and a pain-free back.                  Set Contains:               1 x backjoy posture
