Ever since I hit about 8 months pregnant, I've had a burning sensation in my hips/upper thighs whenever I sit for too long, which is apparently because my expanding belly is pinching a nerve. I wouldn't say this belt is a miracle cure or makes me feel dramatically lighter---late pregnancy is just darn uncomfortable---but it offers enough support to mostly alleviate that nerve problem. The fabric is a soft elastic (think giant bra strap) and I prefer the hook closure to Velcro belts which can snag clothes. It's flat enough that it's not noticeable under a layer of clothing.
