Nishikawa Air SI Hard Double

This item was purchased from a flea market app as a display model.
After purchasing, I washed the cover, used it for 2 days with a sheet on, but it was too firm for my slender build, so I plan to switch to a regular type.
It has already been removed and is currently rolled up and stored.
Since it was only used for 2 days after being a display model, it is close to unused condition, and I believe the urethane has not lost its resilience.
When it arrived, it had a faint, pleasant scent. I'm not sure if it was the urethane smell or something like Febreze.
I am quite sensitive, but I didn't notice it when sleeping.
I do not smoke and do not have pets.
I am listing it at a low price, so I appreciate your consideration.

The second image was taken by me, but I couldn't capture it well due to the small size of my room.
