Description

☆Five Features of the Premium 3.5☆

1. Low-Resilience Material “Ultra Viscoelastic”
Inspired by the low-resilience material said to be developed for astronauts, Ultra Viscoelastic was created.
It excels in elasticity and resilience, changing its shape and rebound force according to body temperature and pressure, fitting the body perfectly like a custom-made product.
This is truly a low-resilience material used 100% for “better sleep.”

2. Distributes Body Pressure on Hips and Shoulders
Regular mattresses concentrate body pressure on the hips and shoulders, compressing blood vessels, impairing circulation, and causing stiffness and pain.
The Premium 3.5 distributes body pressure, gently enveloping the entire body.

3. Keeps the Back Straight for a Natural Sleeping Posture
A distorted spine puts a burden on the neck and lower back.
The Premium 3.5, using low-resilience material, maintains a natural posture.

4. Only 3.5cm Thick, Lightweight and Easy to Handle
With a thickness of just 3.5cm, it achieves the enveloping comfort of a low-resilience mattress.
Lightweight and easy to handle, making it simple to carry.

5. Simply Lay It on Your Current Futon or Bed
No special bed is required.
Your current futon or bed can be used as it is.
No need to replace bedding, making it economical.
Simply lay the Premium 3.5 for a comfortable sleep.
