This is an airweave "Shiki Futon," a high-end mattress. The firmness varies depending on the area, and by using the front and back sides of the cover, you can achieve the best sleeping comfort for each season. I purchased it used, but I'm selling it because the size was a little too large for my intended use. After purchasing, I washed the cover and the fibers inside and dried them in the sun, and then stored it at home. I haven't used it much, and there is no smoking or pet ownership. I think it's still usable without any sagging. When shipping, it will be rolled up and shipped via Sagawa Express's weight-based flying courier service, size 250. If you are in the Kansai area, I can deliver it by my own car, or I can use the "Tanomeru Bin" service. Please consult with me. ◉Size: Width 120cm x Thickness 8cm x Length 195cm (Inner material only 4.5cm) Weight: 9.5kg Reference price: 128,800 yen #airweave #mattress #Simmons #Serta #Sealy #FranceBed
