The double latex futon is an 18 cm thick cotton bed mattress with a latex foam core. The addition of 5-10% polyester to the cotton ensures a higher density and thickness of the futon compared to traditional Japanese futon beds. Nevertheless, it still has all the good properties of a traditional Japanese futon. The double latex futon offers you a soft sleeping surface. The cotton in the futon moulds to your body and supports it, while the latex isolates any movement. Mattress colour: black. Cover material: 100% cotton. Mattress filling: 18 cm mixed fibre mattress with a core of 8 cm latex foam. Mattress filling material: 90-95% cotton + 5-10% polyester.
