How to use a "roll lumbar pillow" for those who have trouble lowering their backs in the morning

We applied for a patent in 2015 with the aim of commercializing the handmade instruction for No. 16 orthopedic patients. Although it was approved as "Patent No. 6774742: Roll Pillow and Roll Pillow Attachment Method," it was difficult to commercialize it after that.
Due to this opportunity, we have decided to jointly develop this product with the handicraft specialty store ``Craft Heart Tokai,'' and we will also be selling it at the Yamada Shuori Pillow Research Institute.
In addition to the orthopedic pillow, we also recommend the roll lumbar pillow.
