WoodyKnows Side-Sleeping Backpack, Sleep Position Trainer, alleviates snoring Caused by Throat Issues (Large 1 Pack)

78%polyester 12%polyethylene 7%polypropylene 3%other Fibers Please check our store to get more details, the replacement airbag, and related products. This product helps you train yourself to develop a side-sleeping habit quickly so that the tongue, soft palate, and loose throat tissues will not fall backwards, blocking the airway. It can only help alleviate snoring caused by throat issues. It is big enough to keep you off your back at night, thus you will not end up sleeping on it or get your spine hurt in the way that wearing a small or hard supporter would. You can adjust the air capacity of the airbag to find the most suitable sleep position. You can send us a message for a free airbag replacement within the 3-month warranty period. This backpack features a three-point fixation on the shoulders and the waist to avoid shifting and sliding around over time. Please note that we randomly ship the two versions, the buckle straps and the touch fastener straps. Size Guide - Two sizes are available. Measure your back width between your armpits but not including your arms. Large size is for people with a back width larger than 16 inches (40 cm). Medium body sized people are recommended to choose the Large Size Backpack.
