Works for me,
Verified Purchase(What is this?)
This review is from: Mesh Lumbar Back Rest Support - Very Firm & Flexible - Fits Almost Any Chairs, Office Chairs, Car/Van Seats
I use this back rest extensively when driving as I suffer from sciatica , It fits over a van seat easily and supports the lower back and I can feel the difference if I drive a different vehicle without transferring the support to that vehicle .
Anything that helps ease the discomfort is a bonus to me , Also I have to add that the support has retained its shape although its light I thought it wouldn,t be up to much but its proved me wrong .
Never tried it in a chair though but great for a vehicle .
