Eairpo Sleep Double Pillow, 2-Level Adjustable Height, Low or High, Thin Memory Foam Pillow, Ideal for Side Sleepers, Relieves Stiff Shoulders,

[Firmly Fits Your Head, Neck, and Shoulders] This ergonomically designed cervical support pillow maintains the natural S-curve of the cervical spine, helping to maintain proper sleeping posture and effectively alleviate wrinkles around the jaw and neck. [Use Two Memory Foam Pillows Together] The butterfly-design upper pillow offers a soft, resilient feel and moderate softness, with a gently concave shape. The lower pillow has a slightly softer, flatter structure than the upper pillow. It supports the weight of the upper pillow and prevents your head from sinking too far. [Use the Upper Pillow as a Single Pillow] The upper pillow measures 60 x 33 x 5-7 cm. It has a slight concave head support area in the center, slightly firmer and higher sides, and a stronger curve in the neck support area than the lower pillow. This pillow is recommended for those who prefer a lower pillow and are looking for a pillow that helps improve their sleeping posture. [Use the Lower Pillow as a Single Pillow] The lower pillow measures 62 x 33 x 5 cm. It is slightly wider than the upper pillow. There is a slight depression in the head support area in the center, but the overall design is flat, making it easy to turn over. [Supports various sleeping positions] The gentle depression structure and slightly firm, high side design make it easy for your shoulders and arms to fit when lying on your side, so you won't feel cramped. There is space on both sides to rest your arms and arms, so you won't have to worry about where to place them when lying on your side, making it easy to sleep with your arms and hands up.
