Review on Samyoung Mesh Back Lumbar Support Cushion | Breathable Office Chair & Car Seat 12" X 16 by James Vachon

The lumbar support is terrific and the texture bumps on the back comforting. While some others I tried have a curve that is overly agressive, this one works well. Well worth the price.Down side is that the elastic strap in the back is not adjustable so it won’t fit many chairs. It won’t work at all on open backed chairs. I had to fashsion "slop stop” to use it on my outdoor patio chairs. (I’ve been leaving it out in the rain and notice no ill effects.)I prefer other deaigns that have buckle in the elastic strap, and verical rear ribs to stablize it in chairs with an open back.Still, over all a useful tool in the back pain arsenal!
