N Sleep Premium Hard PH0 Pocket Coil Mattress

Brand new, unused, and unopened in its original cardboard box.
I purchased this by mistake and it just arrived. Since I was told I couldn't get a refund, I'm selling it.

This is a mattress from the [PH0] series, in a single size.
It features a dual-layer pocket coil construction, offering excellent durability and body pressure distribution.
By combining pocket coils of different firmness in the upper and lower layers, it provides robust support for your body, preventing excessive sinking and ensuring a stable and comfortable sleep.
Furthermore, the use of hard urethane in the filling makes it an ideal choice for those who prefer a firm, solid feel.

The package is compressed and rolled, so you can use it immediately after opening.
*Once opened, it cannot be re-compressed.
*It may take 2-3 days to fully restore its shape after unpacking.
