Abstract

When using a futon cover with an open zipper, fold the futon cover in half lengthwise, then fold that in half widthwise again. This means that when it is reduced to a quarter of the size of the futon, you can close it with the pair of open zippers on both sides. This prevents the futon from collapsing into a compact size.
