I upgraded to this mat from the entry level 2″ disc tourmaline and jade mat. What an incredible difference! I love how soft the amethyst side of this mat is and primarily lay on that side. Other than covering it with a sheet, I do not have to put any blanket or pad between me and the mat since it is comfortable enough to lie on. Since using this mat for the last several months I have noticed that my hip pain and shoulder pain are non-existent now. Also, my sleep has greatly improved. I lay on this mat about 30 min (or longer if I dose off) each night before bed. I used to wake up around 2 or 3am a lot and now sleep through the night until 5 or 6am. I use their shoulder and back mat for in the office (I am an acupuncturist working inside a chiropractic office) and have prescribed these mats to many patients now. This reversible, soft mat is by far my favorite product that I have purchased so far from HealthyWave and I am so looking forward to their new products coming out soon!
