Frequently asked questions

How will my ARQYA products be delivered?

Your ARQYA mattress (Tenkai/Akari/Kaeru) and Tetsu Pillow are efficiently vacuum-packed and rolled into a box (Bed in a Box delivery) for easy handling and swift setup. The Haruki Bed Frame is delivered in a compact box with the essential components pre-assembled.

How long does delivery take?

We prioritize speed and efficiency. Standard delivery typically takes 3-5 business days. You will receive tracking information as soon as your order ships to follow its journey to your home.

Is the assembly difficult?

No. Our Haruki Bed Frame is designed for fast, tool-free assembly thanks to its innovative, pre-assembled design. Mattresses require no assembly—simply unbox, unroll, and allow a few hours for full expansion.

What should I do after unboxing the mattress?

The mattress will begin expanding immediately. While it is safe to use within an hour, we recommend allowing 3 to 6 hours for the foam to fully recover its precise 27 cm (Akari) or 25 cm (Kaeru) profile.

What quality certifications do ARQYA products hold?

Our commitment to safety is uncompromising. All ARQYA foams are CertiPUR® certified, ensuring they are free from harmful chemicals. Our textiles are certified OEKO-TEX® Standard 100, verifying that they are safe and skin-friendly.

Does the Haruki bed frame require a box spring?

No. The Haruki frame’s hybrid structure features sturdy, supportive wood slats that eliminate the need for a box spring, providing a silent, stable, and breathable foundation for the mattress.

What are the main differences between the ARQYA mattress models?

Tenkai (Hybrid): Our premium 4-in-1 Hybrid system featuring pocket springs, foam, Dual Firmness, and Dual Temperature control. Ideal for precision support and motion isolation. * Akari (Viscoelastic): Our advanced viscoelastic (memory foam) option, featuring Gel-Infusion for cooling, and Dual Firmness (Soft/Firm) via flipping. * Kaeru (Foam): Our versatile 4-in-1 All-Foam system with Dual Firmness and Dual Temperature control via a reversible cover. An accessible, highly adaptable choice.

How do I customize the firmness of my mattress?

All three models feature a Dual Firmness design. Simply flip the mattress (Tenkai, Akari, Kaeru) to select the stable Firm side or the pressure-relieving Soft side, adapting the support to your exact needs.

How do the mattresses regulate temperature?

The Tenkai, Akari and Kaeru offer Dual Temperature regulation via a reversible cover (Warm Tencel™ / Cool Chill Fibers). The Akari uses cooling Gel-Infused Memory Foam combined with continuous ventilation for all-year thermal comfort.

How can I adjust the Tetsu Pillow?

The Tetsu pillow contains multiple, rearrangeable inner foam layers. By adding, removing, or stacking these layers, you can precisely adjust the pillow's height and firmness to achieve perfect cervical alignment.

Can I wash the covers?

Yes, for superior hygiene. All our mattress (Tenkai, Akari, Kaeru) and pillow (Tetsu) covers feature a 360° full perimeter zipper and are designed to be fully removable and machine washable (up to 40°C). Always follow the care label instructions.
