New, unopened Nitori Single Mattress T1-CR VB

Thank you for looking.
I purchased this in September 2025, but since I haven't used it, I'm putting it up for sale.
It is unopened.

[Product Description]
This is a firm type mattress. The two layers of pocket coils conform to your body and provide firm support.

Two-layer pocket coil structure. The upper layer of small pocket coils disperses body pressure, while the lower layer of pocket coils provides firm support for your body.

Pocket coils support the body at points, conforming to your body's contours. This provides excellent body pressure distribution, preventing pressure from concentrating on specific areas of the body during sleep, leading to comfortable sleep with less strain on your body.

The exterior is surrounded by urethane foam to prevent deformation and sideways motion.

The larger the contact area, the wider the support area, and the better the mattress's body pressure distribution.

It is always clean with deodorizing, anti-mite, and antibacterial functions.
