- Immediate posture correction and back pain relief: The posture corrector aims to fix or prevent bad posture. With comfortable, strong back and shoulder support, it relieves back, shoulder, neck and clavicle pain, helps muscles remember proper alignment, and supports long periods of standing or working. It helps prevent poor postures caused by laziness and protects overall spine health. - Comfortable adjustable design: Based on ergonomic principles and improved design technology, it is made of high quality materials that are safe for the body and environmentally friendly. It is lightweight, breathable and washable. It corrects posture in the most comfortable way and is suitable as a back support for chest sizes from 35 to 43 inches. - Invisible under clothing: Easy to wear thanks to the Velcro closure and the elastic soft shoulder strap with foam padding. You can adjust it to achieve the ideal fit. The posture corrector is invisible under clothing and can be worn at work, during sports, yoga or leisure. It allows total freedom of movement without hindering daily life and functions as a back stretcher. - Usage recommendations: Start with 30 minutes a day. If comfortable, gradually increase duration in 15 minute increments and then wear up to 2 hours. Tighten the straps regularly to pull the shoulders further back until they lie flat against the wall. Over time, muscle memory will help your body adopt the correct posture even without the corrector. Wear it when you feel you are starting to slouch.
