New, unused Eight Sleep "92" SD

This is a mattress that I personally use and am incredibly grateful for, as it has eliminated the back pain I suffered from for over 30 years. I love it so much that I prepared a spare, but unfortunately, I have to sell it because my bed size is changing.
Recommended for those who prefer a firmer mattress!
Retail price: ￥198,000-

Focusing on sleeping posture, it supports your body in a balanced way.
It is said that when sleeping, 8% of your weight is on your head and 92% is on your body, making the mattress extremely important.
This mattress firmly supports that 92% of your body, maintaining a correct sleeping posture as if you were standing.
It is also recommended for improving back pain, stiff neck and shoulders, and snoring (sleep apnea).
One side features a breathable honeycomb mesh fabric for coolness in the summer, while the other side uses a knit fabric and a special heat-retaining material called Metalon for warmth in the winter. You can use both sides depending on the season.
