Foam is Good
Number One, your futon mattress must contain foam, and lots of it, if you plan to sit on it a lot. Durable futon mattresses always contain foam, usually contain cotton batting, and sometimes contain springs.
And Thickness Counts
Number Two, the thicker the better. Anything under 6 inches thick just won’t cut it for you. Most good futon mattresses are about eight inches thick. That’s hefty enough to be comfortable, thin enough to let your futon frame open and close okay and to fit into ready-made futon covers.
But the Fiber is the Most Important
Futon mattresses always contain some form of fiber batting. Cotton is the most popular, but sometimes you’ll see wool or synthetic batting too, which is more expensive. You’ll see all of those at Futons & More. When you look at the cross-section of the mattress construction, pay close attention to the batting. Do you see any “clouds” of color, or lots of threads mixed in? Beware! That’s “shoddy” filler, which is chopped up clothing and fabric scraps. “Shoddy” makes the futon seem fuller and puffier in the store, but it will flatten out faster when you sit on your futon at home. Our futons are made by Wolf, and the fiber is a terrific blend of high-quality cotton and polyester.
