Mueller Adjustable Posture Support review

The Mueller Adjustable Posture Support is the pick for people who want a light, breathable reminder rather than a rigid brace. Mueller Sports Medicine describes light upper-back support from elastic straps with soft padding, made from a cotton material it says is 75% lighter and 34% more breathable. Two sizes cover chest measurements from 34 to 44 inches (OSFM) and 42 to 53 inches (LG/XL), and the straps adjust with red hook tabs. It slips on like a backpack, can go under or over clothing, and Mueller says it suits home, work, daily activities and workouts. It costs $24.99 to $29.99 depending on size and is listed as HSA/FSA eligible. The limits are clear from Mueller's own wording: this is light support that gives gentle reminders, so people with a pronounced slouch will want something firmer. The page also calls the cotton machine washable while the care instructions say hand wash cold.
