Hirune Mattress
Hirune Mattress
The Hirune is the simplest mattress we make. And the firmest.
Hirune (昼寢) means "nap" in Japanese — short, functional rest. That's exactly how we thought about this mattress: no unnecessary layers, no extra promises, but with the right structure for firm rest that doesn't give way.
It's a pure high-resilience foam mattress, 12 cm tall, extra-firm. It's not our main model — it's the right option for those who need something practical, firm, and at an unbeatable price.
Who it's for
- Those who need a firm mattress without a big investment
- Guest beds or short-term rentals
- Those with back pain who prefer a traditional "hard" mattress
- Under tall bases or slatted frames that need a thin mattress
What the Advisor says
"When someone calls me saying 'I just need a firm mattress, no fuss' — it's the Hirune. I won't promise you a mattress for 10 years of main use, but for what you need (guests, secondary room, simple and firm) it does the job honestly."

Frequently asked questions
Is it too thin?
12 cm is thin for a main bed in daily use. It works well for guests or on tall frames. For daily use, consider the Kumo (medium foam) or Kaizen (more comfort).
How does it compare to the Kumo?
Hirune is extra-firm and 12 cm. Kumo is medium firmness and 23 cm. If you want "traditional hard" and cheap, Hirune. If you want comfortable + affordable, Kumo.
Is it good for a guest bed?
Yes — it's exactly the use many customers buy it for. Durable, cheap, easy to maintain.
