Bests & Worsts Reviews from Amazon

I have chronic lower back pain and have used lumbar supports of several different varieties over the last 15 years. I needed to replace the support used in my car and I thought that a mesh version might be better than the memory foam because it can keep my back ventilated. After experimenting with this support on several different type of chairs I've determined that it is not suitable for my condition. The design of the support relies on the top and bottom part of it to rest and press against the back of the chair. For my needs the bottom part of the support needs to meet (rest on) the seat of the chair so that I can get the support in my lower back. For any chair that has a gap between the back and the seat (like many) the bottom part of the support slides into the gap and the resulting support is minimal. For all the pictures showing the item in use on this listing there is no pressure on the support. If there were you'd see how the bottom part gets pushed into the gap. For chairs where the back does meet the seat (like a car seat) the back cannot be soft (like a car seat). Reason, as previously stated the design of the support relies on the top and bottom of it to push against the back of the chair. For upholstered chair backs, what happens is the minimal surface area of the support (basically a hard wire) pushes into the soft seat back. Once it does, it offers little in the way of support. So, for me, the only type of chair that this actually works on is a rigid chair back that meets the seat like, perhaps, a dining room chair. It does not provide support for office chairs and car bucket seats. When looking for a new support it was a toss-up between the memory foam (not just regular foam) and the mesh. I thought I'd give the mesh a try and as a result of my experiments, I'm returning this support and going back to the tried-and-true memory foam for my needs.
