Cecile Co., Ltd. (Headquarters: Shinjuku-ku, Tokyo; Representative Director and President: Masakazu Murakami) began selling the 'Gussuri Sleep Design Pajamas (unisex)' from March 27. These special pajamas were designed with attention to common concerns such as 'pajamas not feeling right' or 'difficulty turning over in bed,' focusing not only on material and design but also on ease of movement and comfort during sleep.
■ 'Pajamas for Sleep' Pursued Through Joint Development
Previously, our company's product planning for pajamas and sleepwear emphasized material feel and design. However, in recent years, interest in sleep has grown, and comfort is now sought not only in bedding but also in sleepwear. Therefore, by incorporating insights from sleep professionals, we developed the 'Gussuri Sleep Design Pajamas,' aiming for comfortable sleepwear that traditional pajamas could not adequately provide.
■ Innovations Aimed at Reducing Stress During Sleep
Point ① Soft and Stretchy 'Gussuri Material'
This soft, stretchy material allows for relaxation without hindering movement of elbows, shoulders, and knees during sleep.
Point ② 'Easy-to-Move Design' for Easy Turning Over
By shifting the side seams forward, we reduced tightness around the shoulders, back, and armpits, making it easier to move during sleep.
Point ③ 'Relaxed Design' Around the Thighs
By shifting the seam position of the pants, we created extra room around the thighs, eliminating a constricted feeling and allowing for easy leg movement.
Point ④ 'Sweat-Absorbing and Quick-Drying Function' to Quickly Absorb Sweat During Sleep and Dry Easily
The fabric is pleasant to the touch and prevents stickiness even when sweating, ensuring a dry and comfortable feel during sleep.
