This mattress has a luxurious firm feel. We've got lots of highly resilient foam and bonded polyester to create a futon that is comfy to sit on, and still performs well as a supportive sleeping surface. The 1.8 density foam provides strength, flexibility and firm comfort. The bonded polyester fiber on the top allows the desired cushiness needed for sitting comfort. Solid natural canvass duck fabric on the outer shell for tough and long lasting durability. This is our # 2 seller in this category.
