Sleep Support x Acupressure Structure - Old Model Health Wave DC Version (Semi-Double)

◆ Product Overview
This is a pre-owned Health Wave DC Version Deluxe (110cm width) from Japan Direct Sales. It is a rare American Deluxe Size, slightly smaller than a semi-double, which is uncommon in the domestic market. This size allows for comfortable sleeping even in limited spaces.
Key features include an ergonomic uneven acupressure structure, tourmaline-processed thermal support, and a reversible design that offers breathability in summer and warmth in winter. It prevents body sinking and provides firm support for your sleeping posture. This mattress is well-regarded and supported by the American Chiropractic Association.
It is lightweight and easy to carry. This is the original model that the current Shohei Ohtani mattress is based on.

◆ Appeal of the Old DC Version
While recent gel-infused types and new models (like the Suyayaka DCDX) are priced in the 300,000 yen range, this older DC version features a moderate firmness + tourmaline thermal structure. It is recommended for those who want firm support for their spine without sinking too much into the mattress.
Furthermore, unlike gel models which some find feel cold in winter, this product utilizes tourmaline material for natural warmth and heat retention. Its reversible design is excellent for addressing both winter cold and summer stuffiness.
