Mattress: Kumo no Yasuragi Premium - Firm, Thick, Extra-Thick, High-Resilience, Anti-Mite

【POINT 1】 Meticulously Crafted 5-Layer Structure, 17cm Thickness
The Kumo no Yasuragi mattress features a structure designed to reduce strain on your lower back with its resilience, pressure distribution, and appropriate firmness.
It boasts a substantial 17cm thickness and a 5-layer construction: a convoluted profile mattress, a high-resilience urethane mattress, another convoluted profile mattress, and a reversible layer (Mighty Top? II adECO and Lorraine Down).
【POINT 2】 Kumo no Yasuragi's Unique Structure! Cross-Cloud Manufacturing with Convoluted Profile Mattress x High-Resilience Urethane Mattress
By combining two types of mattresses, the convoluted profile mattress and the high-resilience urethane mattress, in a 3-layer structure, we support your ideal sleeping posture.
The convoluted profile mattress supports body pressure at multiple points, while the high-resilience urethane mattress provides a high rebound, releasing and dispersing excess force. This is a mattress that is gentle on your lower back.
【POINT 3】 Commitment to Safety and Security
(1) Produced in a domestic factory
(2) Uses filling that is breathable, mite-resistant, antibacterial, and odor-resistant
(3) Meets formaldehyde standards
