Nitori Single Mattress N Sleep Luxury LH3

Selling because it doesn't fit my body.
The receipt shows a purchase in late July, but it was delivered in mid-August, so it has been used for less than a month.

I used a sheet and a mattress topper on top of this, so there are no stains.
I will sell it with shipping included.

Nitori's highest-grade mattress. The bottom features a dual-layer alternating pocket coil system, and the topper has alternating micro pocket coils and a triple-layer alternating pocket coil mattress. The triple-layer pocket coils combined with two layers of cushioning (latex and C-CORE?) provide a balanced firmness and resilience to support your body and maintain an appropriate fit for your sleeping posture.

With a contact area of 5100 cm2, this is a top-tier firm mattress. It features a triple-layer pocket coil structure using two layers of pocket coils in the bottom section and one layer of micro pocket coils in the topper. This is a mattress with the highest durability rating.

The moderate elasticity of latex conforms to your body. The resilience of C-CORE? supports turning over. Furthermore, the breathable material helps prevent stuffiness in the summer and maintains a comfortable temperature in the winter with a warm air layer. The alternating arrangement of 10.0mm diameter micro pocket coils supports your body at finer points, providing excellent pressure distribution and a superior sleeping experience.

The main base is divided into three zones, with different coil wire diameters used:
Upper layer, lumbar area: 1.8mm, 6 coils
Upper layer, leg and shoulder area: 1.6mm, 6 coils
Lower layer: 1.8mm, 5.5 coils
This design enhances lumbar support.
*Wire diameter refers to the thickness of the pocket coil springs.
