Yamada Aori Pillow Laboratory Doctor's Pillow Orthopedic Pillow 50 x 25 with Pillowcase for a Good Night's Sleep, High Resilience

[Custom-made Orthopedic Pillows] Since 2003, we have provided custom-made orthopedic pillows to over 60,000 customers. While providing orthopedic pillows required in-person measurements, we have now developed and sold a product that allows customers to adjust the height of the pillow themselves after purchasing it. We developed this product with the hope that many people will use orthopedic pillows. [Relieve stiff neck, shoulder, and neck pain!] Our research has shown that even if you have a stiff neck, using the right pillow can significantly improve neck pain and stiff shoulders, even if it doesn't cure the condition itself. The important thing isn't whether you have a stiff neck or not; remember that even if you have a stiff neck, using the right pillow can relieve painful symptoms. Starting tonight, if you have a stiff neck, adjust the height and use the right pillow. Orthopedic pillows incorporate the results of years of clinical research and reduce strain on the body while you sleep. [High-resilience material for easy turning over and a restful sleep] This pillow uses the same material as the custom-made [orthopedic pillow] developed by Shuri Yamada, an orthopedic surgeon in charge of the pillow outpatient clinic at No. 16 Orthopedic Clinic. The pillow height can be adjusted in 5mm increments to suit your needs, and the flat structure makes turning over easy. The pillow is made of a firm, high-resilience material to maintain its height. [Height Adjustment Automatic Height Measurement System] We include an instruction manual to ensure you sleep at the same pillow height as when you measure in person. Customers who are unsure of the instruction manual or who just want to know the optimal pillow height can rest assured. The [Automatic Measurement System], developed based on the measurement data of 60,000 customers, calculates the optimal pillow height and allows you to adjust the pillow height yourself from 4.0 cm to 9.0 cm. If you wish, you can find instructions in the instruction manual, and after purchase, you can access the [Automatic Measurement System] webpage. Please feel free to use this as well. [Perfect as a gift] Also suitable as a gift for celebrations such as birthdays, Christmas presents, weddings, births, moving, school entrance, employment, new homes, renovations, mid-year gifts, year-end gifts, Father's Day, Mother's Day, 60th birthdays, and Respect for the Aged Day.
