Bests & Worsts Reviews from Amazon

There are several very nice features about this cushion for lower back support. The construction is high quality: soft but durable exterior mesh fabric, solid straps with easily adjustable strap length for holding the cushion in place, and a firm but not stiff memory foam interior. Each strap also includes a removable section, providing a very large range in the length for each strap. I'm still experimenting with the best way to secure it in the driver's seat of my Model S, which has a deeply curved sports-style seat back, since simply wrapping the straps around the back leaves the cushion suspended between the protruding left and right sides of the seat back. However, I like the cushion itself enough that I'm determined to find a solution.
