Tempur PRIMA PLUS Semi-Double Soft Low-Rebound Mattress

Tempur Prima Plus
Semi-Double, Soft
Width 120 x Length 195 x Thickness 25 cm

Purchased in December 2024 at the Tempur Kobe Sanda Premium Outlet store for ￥221,100. (I believe it was 30% off.)
The mattress itself is in beautiful condition as it was always used with a mattress protector and sheets, but upon visual inspection, there are minor stains in two places (see images 11 and 12).
No smokers, no pets.

I primarily sleep on my side and bought this on impulse thinking a softer mattress would alleviate shoulder pain, but the cause was elsewhere and it didn't resolve the issue.
It's an expensive mattress, so I continued to use it, but I'm accustomed to firmer mattresses and am selling it due to this change.

Please purchase with the understanding that this is a used item.
