WAVE Σ (Regular) Bed Mattress

The uneven surface and middle layers have two types of urethane foam with different hardness arranged in a mille-feuille pattern to gently fit your body lines.
It also supports your body by following the curve of your shoulders to your hips when you sleep on your side.

Monogram slits for increased breathability

The slits engraved into the surface of the urethane allow moisture that tends to accumulate in the sleeping area to quickly escape, creating a fresh, stuffy environment.

WAVE Σ is available in two hardness levels.

You can choose from two types of mattresses, hard (firm) and regular (soft), depending on your body type. The table is a guide for your selection.

Can be further customized to fit your body type

For those with particularly extreme unevenness, the support pad (sold separately) can be used to adjust the amount of support provided from below in specific areas.
By placing support pads in the gaps around your waist and behind your knees, you can provide more support for those gaps and sleep more comfortably.

It's more comfortable for side sleepers as there's no pressure on the shoulders.

I think the biggest problem for people who sleep on their side a lot is pressure on the shoulders.
When I wake up, I feel like my shoulders are kind of heavy...

The solution to this problem is to use a higher pillow, which can alleviate the pain to some extent, but there is a limit to how much of a difference this can make. The best feature of this mattress is that it flexibly accommodates the protrusions of the shoulders and pelvis.

Recommended for slim people and those who tend to sleep on their side.

This mattress has been on the market for over 20 years and has been constantly improved based on customer feedback, making it a highly reliable product.
With daily use, the firmness will adapt to the sleeping style of the person, and the comfort will improve each time you use it. Because it softly wraps around the body, it is recommended for people with a tight S-line of the spine or shoulder width, or other people with pronounced unevenness.
