Back Stabber
Review by Insultinjury on 30 Dec 2017 review stating Back Stabber This product has 6 attachments for the straps.Every one of them has a ~1/2 inch spike that extends forward into your back, making driving a painful experience and making back problems worse.When I returned it, I felt every cushion in the store and they all had the spikes.Photo would not load, so feel for yourself before you buy this back-stabber product.The worst for me was at the bottom center (spike extends forward from the rigid frame below the padding.Remember it's different driving when pressed against the seat in a moving car.It's not like in the store sitting in a demo car seat with cushion, no movement, and lots of space around you.
