[EX Q]: I slouch at work sitting at a desk all day. Was trying to find a good solution to help alleviate the slouching and back pain. This posture corrector has definitely helped! I am sitting straighter and the pain has lessened.This posture corrector has given me strong support for my back, without restricting my movements.
[EX A]: positive
