Our double latex futon is an 18 cm thick cotton mattress with a latex foam core. 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 double latex futon provides you with a soft sleeping surface. The cotton in the futon conforms to your body and supports it, while the latex isolates every movement. Mattress color: Natural. Cover material: 100% cotton. Mattress filling: 18 cm blended fiber mattress with an 8 cm latex foam core. Mattress filling material: 90-95% cotton + 5-10% polyester.
