Review on 🪑 The Original McKenzie Slimline Lumbar Support: OPTP's 705 Model for Effective Back Pain Relief by Robert Pierce

Well designed and built. Holds securely to my office chair and doesn't slip. This is the second one I own. After many years, the rubber band was the first to stretch, so I replaced it. However, the replacement feels more compressible (squishy) than the first one I had. When I lean on it, it compresses to less than 1 inch thick, which is insufficient for lumbar support. If the foam was harder and less compressible I would give it 5 stars. Update October 2017: I recently purchased OPTP's Original McKenzie® Super Roll (708) and found it much better - much stronger. I recommend the latter if you want strong lumbar support with the same thickness.
