With the increase in desk work, smartphone use, gaming, and video watching, many people are experiencing fatigue in their neck and shoulders. The cause may be straight neck! Straight neck is a condition where the neck (cervical spine), which should have a gentle forward curve, becomes straight. This happens when we spend more time looking down, causing the position of the neck that supports the head to shift, increasing the burden. Hearing about these painful concerns, we collaborated with a chiropractor to develop the Seitai Neck Sofa, which corrects the neck to the proper position and relieves neck and shoulder pain! 6 Key Features! (1) Built-in shape-memory wire for a perfect fit for any neck (2) Slim design that won't feel tight even when wrapped snugly (3) Low-rebound cushioning for comfortable long-term use (4) Folds compactly for easy portability (5) Co-developed with a chiropractor by a #1 rankedseitai brand (6) JAPAN QUALITY you can trust, from design to production. Is your neck properly aligned? Aligned means to be firmly set in place. The cause of neck and shoulder discomfort is that the neck is not set at the correct angle. Our heads are actually very heavy. For a person weighing 70kg, the head weighs about 4.0kg. That's the weight of a typical bowling ball! The neck is constantly under that much strain. The burden increases significantly when the neck angle is tilted... When the neck angle reaches 60 degrees, the burden increases more than 5 times! If this continues for a long time, the neck alone cannot support the weight of the head, and the burden extends to the shoulders and lower back... The RAKUNA Seitai Neck Sofa lifts the chin directly by wrapping the wire-built-in cushion from the front, maintaining the correct neck angle. It directly prevents the causes of poor posture and straight neck. By bending the shoulder area, it fits snugly and won't slip or fall off. The filling uses low-rebound urethane foam, which is also used in medical and nursing care products. It reduces the burden on the neck and provides a comfortable fit without feeling constricting.
