Thank you for looking.

This is a Nishikawa mattress purchased about 5 years ago for over 150,000 yen. I bought it thinking it might absorb vibrations, as I was suffering from insomnia due to external vibrations. However, it was ineffective, so I stopped using it after 2-3 times. Therefore, it is in beautiful condition. (The user was a petite woman around 160cm tall, and a thick sheet was used on top of the mattress.)
The mattress cover has been washed (see 3rd photo). I will include it, but I can discard it before shipping if you do not need it.
