Description

☆Five Features of the Premium 3.5☆

1. Ultra Viscoelastic Material
Developed with inspiration from the low-rebound material said to be created by a space agency for astronauts, Ultra Viscoelastic excels in elasticity and resilience.
Its rebound strength and shape change with body temperature and pressure, fitting perfectly to the body like a custom-made item.
This material is 100% used for a truly “comfortable sleep.”

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

3. Maintains a Straight Back for a Natural Sleeping Posture
A misaligned spine puts strain on the neck and lower back.
The Premium 3.5 uses low-rebound material to maintain a natural posture without strain.

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

5. Simply Lay It on the Current Bedding
No special bed is required.
Current futons or beds can be used as they are.
No need to replace with new bedding, making it economical.
Simply lay the Premium 3.5 for a comfortable sleep.
