Hisui Mattress
Hisui Mattress
Hisui is jade — the stone the Japanese associate with harmony.
Hisui (翡翠) is Japanese for "jade" — the stone of balance. This is our mattress for those seeking firm support with the adaptability of viscoelastic foam. It combines the best of two worlds: the stability of high-resilience foam, and the pressure relief of viscoelastic foam.
It is a mattress designed for those who primarily sleep on their back, experience back pain, or are looking for a bed that keeps the spine aligned all night long. 26 cm high, stable firmness, no springs.
Who it's for
- Those who primarily sleep on their back
- Those who wake up with back pain or want to prevent it
- Those who prefer the full foam feel (no springs)
- Those seeking stable and long-lasting firmness
What the Advisor Says
"When a client tells me their doctor or physical therapist asked for 'more support,' I usually recommend Hisui. The viscoelastic foam relieves pressure without giving in. It has been the most chosen item by those who sleep on their back and want to prevent pain."

Frequently Asked Questions
Is it too firm?
It's firm — but not as rigid as Samurai. It has viscoelastic foam on top that relieves the "hard" sensation. Those who have never slept on viscoelastic foam will feel "enveloped."
How does it compare to Kaizen?
Hisui is firmer and more durable. Kaizen is softer, with a more pronounced "memory foam" sensation. For pain: Hisui. For pure comfort: Kaizen.
Can I sleep on my side too?
Yes, but if you sleep more than 50% of the time on your side, consider Sora or Takumi — they adapt better to the shoulder.
