【3D Structure & 5-Area Design Low-Rebound Pillow】 This pillow adopts a 3D structure based on human ergonomics. It's designed with five areas in mind: the back of the head, around the ears, the neck, shoulders, and arms, gently cradling the head in the central indentation to support a natural posture. It's designed to accommodate various sleeping positions, such as side and back sleeping. 【2-WAY Height Adjustment】 Features a dual-sided design with different heights. The lower side (approx. 6cm) is suitable for back sleepers, while the higher side (approx. 8.5cm) is easier to use for side sleepers, allowing you to choose based on your preference and body type. The rounded shape, inspired by clouds, helps stabilize the placement of your head and arms. 【High-Density Low-Rebound Urethane Foam】 Made with high-density memory foam material, it provides moderate resilience without excessive sinking. Pressure on the head and neck is less likely to concentrate in one spot, offering a feeling of being enveloped. 【Includes 2 Pillow Covers & All-Season Use】 Comes with two types of covers: a seasonal cover and a cooling contact cover. You can switch between them according to the season or your preference, and both are removable and washable. 【Product Information】 Size: Approx. 53 x 29 x 11cm / Weight: Approx. 850g Contents: Pillow body, 2 pillow covers, Japanese instruction manual ※ The seasonal cover is attached upon delivery.
