Airy Mattress EXTRA Single - Scheduled for Deletion Soon

Thank you for looking.
I used this for about half a year after purchasing it. While it had benefits like not producing dust, I didn't prefer the cushion feel of Airy, so I stored it in a dresser. No smoking, no pets.
As you can see in the photos, there is considerable signs of use. There is also a tear in part of the cover. I'm listing it because I thought someone might want to try it out or use it as cushioning material.
The size is approximately 95cm wide x 198cm deep x 11cm thick, with its thickness being a key feature.
The selling price is almost entirely for the fees (970 yen) + shipping (8600 yen). It will be shipped via Packing and Shipping Mercari便.
Please contact me if you have any suggestions for alternative shipping methods to reduce costs.
I plan to dispose of bulky waste soon, and if it doesn't sell, I will discard this mattress along with it, so it will only be listed until then. If the listing deletion is delayed, I apologize in advance, but we will have to cancel the sale.
