The middle strap at the hip makes for greater security and comfort for my husband. Additionally this extra strap makes positioning him in a chair easier
Honestly, compared to the 2 other slings I tried there are no weaknesses that I have found or can think of.

My Husband is 82 and about 236 lbs. He is unable to transfer or walk. As his sole care giver I need to transfer him as easily as possible.
