This is what QUALITY looks like on all levels from customer service to the HIGHEST quality materials in their products, you immediately feel it when you open the beautiful packaging. My mat arrived the day after I had an MRI with contrast, which unfortunately leaked into my arm and I was feeling nauseous and pretty awful. I set up my mat as soon as I opened it and layed down on it for 1 hour. After my nausea and fatigue were gone and I felt better again. I was rather amazed just how quickly it helped me. My friend wanted to try it and he woke up 1.5 hours later and he never naps during the day. The problem is he's going to want to keep using it. This is definitely money well spent. You get what you pay for and to be honest I'm surprised they don't cost even more but I appreciate the affordability and excellence in your products. Thank you
