Our Coco Futon is a 16 cm thick cotton mattress with a core made of coconut fiber boards. By adding 5-10% polyester to our cotton, we ensure a higher density and thickness of our futons compared to traditional Japanese futon beds. Nevertheless, it retains all the good qualities of a traditional Japanese futon. The Coco Futon offers you a medium-soft sleeping comfort. The cotton in the futon adapts to your body, while the coconut board provides support. Mattress color: Black. Cover material: 100% cotton. Mattress filling: 16 cm mixed fiber mattress with a core of 3 cm coconut fiber board. Mattress filling material: 90-95% cotton + 5-10% polyester.
