How about hihip pelvic orthosis?

I've been using the Korean hihip Pelvic Correction Pad for 2-3 weeks. It drags your hips like a pair of hands, dispersing the pressure on your waist and pelvis. Sitting in a correct posture can really reduce a lot of pressure on your back, and it hurts less when sitting. And naturally correct your sitting posture and figure, and you won't stoop again. After sitting up for a long time, even walking seems extra tall and straight. The most critical use is quite convenient. You don't have to turn on electricity, just sit on the office chair.
