If you suffer from back pain, you probably have tried a lot of different products with mixed success. This Lumbar support pillow will vary in effectiveness based on how you use it. These are the use cases I tested: Behind me on a couch. Rating: 7/10. Added some good support where there was minimal to none before. Behind me driving a car. Rating: 10/10. This product really shines here. The support was perfect. It adds the right amount of support and my back felt much better. Behind me in an office chair: Rating 3.5/10. This is the listing's essential use case, and it is where the support proved the least helpful. In fact, where the other use cases made my back feel better, this one made my back feel worse. Obviously all these vary based on what couch I have, what car I drive, and what office chair I use, but I feel that this pillow is a worthy inclusion depending on your use case. The quality seems nice with a decent amount of "squish" while not being too squishy.

This felt so good on my back I had to order second one for my office chair. The support, comfort, and ease of installation makes it worth the money. I have tried many support pillows before this is the best out of all of them. My back pain has decreased after a week of use.
