For those who prefer a softer feel
We enhanced the cushioning by using 3D cushions on the top and bottom layers of the core unit.
By adding thick, long horsehair to camel and yak wool, pressure distribution is further improved.
A master mattress that surpasses springs, luxuriantly using high-grade natural fibers.
This is a made-to-order mattress meticulously crafted one by one by a master who is thoroughly familiar with materials and construction. It is bedding that allows you to sleep comfortably throughout the four seasons, luxuriously using high-grade natural fibers such as horsehair, yak, and camel.
Furthermore, we eliminated the vibrations and swaying often associated with steel coil springs, and pursued both cushioning and ease of turning over. This is a natural, high-performance mattress that Iwata confidently recommends.

Four Features of "Larkowl"
Comfortable and breathable: While conventional mattresses using urethane etc. had the problem of poor moisture release and stuffiness, the natural materials used in "Larkowl" excel in humidity control and are remarkably breathable. It creates a high-quality sleeping environment.
Pleasant warmth: Luxuriously uses wool from two-humped camels, which endure extreme cold of -40℃, and yak wool, which adapted to even harsher environments. The porous fibers with excellent heat retention trap air, preventing body heat from escaping and delivering pleasant warmth.
Ease of turning over: High-grade natural fibers are layered such that the fibers become finer in the upper layers. Furthermore, in combination with the polyester core material, sleeping posture is stabilized, and turning over becomes easier.
Supple cushioning: The unique laminated structure provides supple cushioning. It envelops the body while suppressing sinking, eliminating pressure. It heals daily fatigue and supports a comfortable awakening.

Certified as a Kyoto Smart Product in recognition of our commitment to “circular design that minimizes waste and carbon emissions”
Iwata Co., Ltd.'s mattress "LARKOWL" has been recognized as a "circular design mattress that minimizes waste and carbon emissions" by the Kyoto Chiesango Creation Forest (Chairman: Yoshiko Tsukamoto). We received the "Reiwa 5th Kyoto Smart Product" certification and were awarded a certificate on December 13th. IWATA's bedding company pursues the creation of environmentally friendly products based on its corporate policy of ``Being in harmony with nature from the moment you sleep.''
About IWATA's purpose
Through our corporate activities, we aim to achieve "harmony with nature" from two approaches. One is to provide ``high-quality sleep that is in sync with the rhythms of nature'' to the busy lives of modern people. The other is ``manufacturing within the limits of nature.'' This is an attempt to shift from a one-way linear economy of mass production, consumption, and disposal to a sustainable circular economy. In order to realize a decarbonized society, it is necessary to expand renewable energy and transition to a circular economy. In Eastern thought, there is the idea of ``the union of heaven and man (heaven = the universe, nature and humans are one).'' Following the teaching that humans are part of nature and that our lives are closely related to nature, we would like to develop products that respect the harmony between nature and people's lives, and build a sustainable manufacturing process. We hope.
