Final Price Drop KOKI Mattress 5-Zone Pocket Coil Mattress

Thank you for viewing.

Retail price: ￥53,200 (including shipping)

This is the original mattress installed at Super Hotel. It's popular for how well you can sleep on it.
Purchased in May 2025. Used a few times with a mattress protector, but it didn't suit me, so I'm selling it.

Shipping will be via Tanomeru-bin (a shipping service), so shipping is free.
