Product Overview of the Top-Tier "REGALIA PLATINUM" Three Models

Perfection
This high-grade model features the latest materials with both low-resilience and high-resilience properties, as well as new structures that enhance breathability and fit, and antibacterial and deodorizing treatments. It uses Japan's highest-grade 9-inch pocket coil with center-hard specifications.

By adopting Japan's highest-grade 9-inch pocket coil, it deeply and firmly absorbs body contours,
improving sleeping comfort and the body's fit during sleep.
The side fabric newly uses Sanitized-processed fabric with antibacterial and deodorizing effects.
The new "Flexflow 2.0" material, with excellent breathability and elasticity, is newly adopted as a cushioning material between the urethane and coil layers,
further improving pressure distribution.
The new "Adaptive Foam," a new type of high-resilience foam, is adopted, providing both the gentle fit of low-resilience and the firm support of high-resilience.

improving breathability and body fit.
The center-hard specification, with increased coil wire diameter in the center, reduces lumbar sinking
and enhances durability.
The "Full Body Surround Structure," where the sides of the mattress are covered with high-density urethane that considers breathability,
provides comfortable sleeping comfort to the edge of the mattress, and also prevents lateral sway and deformation of the edge.
and also prevents lateral sway and deformation of the edge.

Grandeur
The double-deck specification of 3.5-inch pocket coils provides rich elasticity. This high-grade model achieves the ultimate softness and fit through a multi-layer structure using the latest materials, including new foam that leads to a gentle sleeping comfort and low-resilience material that prevents heat buildup.

The double-deck structure, with 3.5-inch pocket coils stacked in two layers, improves elasticity and pressure distribution,
reduces vibration from movements like turning over, and contributes to improved durability.
The new "Chilly Wave" low-resilience foam, which absorbs heat with small bead-like gels and has a pinhole structure to prevent heat buildup, is adopted.

The Regalia
The triple-deck structure, using three types of specially shaped foam with coil functions, achieves a refined and deep sleeping comfort that surpasses conventional steel wire coil mattresses. By adopting the latest materials and new structures that enhance breathability and fit, this top-tier REGALIA model realizes the ultimate sleeping comfort.

The center-hard specification, unique to coil-less types, with high-resilience urethane set in the center of the honeycomb structure, is newly adopted to reduce lumbar sinking
and enhance durability.
and enhance durability.
The new structural unit foam "Progressive Core," resembling interlocking gears,
improves pressure distribution and also enhances breathability like a pump.
The triple-deck structure, combining the honeycomb core and progressive core with "DNA coils" (glass fiber wrapped in low-resilience material) as coil functions that provide excellent pressure distribution and shock absorption,
coil functions as glass fiber wrapped in low-resilience material called "DNA Coil," added to the triple
deck structure, achieves REGALIA's top-tier, body-friendly sleeping comfort.
The side fabric newly uses Sanitized-processed fabric with antibacterial and deodorizing effects.
The new triple-deck structure using specially shaped foam without steel wire coils significantly reduces vibration during movement,
and is also an environmentally friendly mattress that is easier to recycle.
Despite being a thick 42cm mattress with a multi-layer structure of high-performance materials, the double size weighs approximately 49kg,
achieving approximately a 20% weight reduction compared to current models. This particularly reduces the burden of making the bed for women and the elderly.

"REGALIA" is a premium mattress brand born from the joint development of Kingsdown, Inc., a US company that has pursued "the best sleep" for over 100 years, and Otsuka Furniture, which has proposed quality sleep in Japan since its founding. Since the first Kingsdown mattress was introduced to the Japanese market in 1993, it has been refined to suit Japan's sleeping environment and needs, realizing "gentle-on-the-body sleeping comfort as if floating on clouds" by fusing carefully selected materials with the latest technology and uniquely developed structures. True to its name, which signifies the crown, scepter, and orb as symbols of royalty, "REGALIA" promises the ultimate sleep.

Kingsdown, Inc. was founded in 1904 in North Carolina, USA. Since then, for over 100 years, as a specialist mattress manufacturer, it has continued to pursue ideal sleep under the corporate philosophy of "Sleep to Live." The company has its own research facility where new materials and technologies that lead the industry, as well as research and verification related to sleep, are constantly conducted. Through the accumulation of unique know-how cultivated over more than a century, it has established its position as a luxury mattress manufacturer. Its achievements are highly regarded worldwide, including being the first mattress manufacturer to receive the "Award of Excellence," the most prestigious award in the American furniture industry.
