Serta Soft Coil Spring Mattress, Made in Japan

Double Size
Domestic Coil Spring Mattress
Serta's Pocket Coil is SWRH82 B Grade C

I recall it costing around 200,000 yen.

I used the soft side, rotating it once a month to prevent sagging.
I aired it out irregularly, but frequently when changing sheets.

It has ventilation holes on the sides to prevent moisture buildup, and the soft side has a gentle feel but provides firm support without sinking.
The reverse side is for those who prefer a firmer feel, with a solid touch against the skin.

The soft side is also recommended for couples with different firmness preferences.
Even with differences in body type and weight, the soft surface with firm support underneath makes it ideal for a petite woman and a man close to being overweight to sleep in the same bed, as recommended for this product.

It is the highest quality standard for bed mattress spring wire materials according to JIS standards.
Serta is one of America's top three bed manufacturers (3S: Sealy, Serta, Simmons), and in Japan, Dream Bed holds the license agreement for its sale.

As the number one bed manufacturer in U.S. hotel market share, it has been introduced in numerous luxury hotels and suites, and is a bed brand that receives top ratings for both comfort and quality.

Produced in Hiroshima, Serta products available for purchase in Japan are basically all made in Japan.
