To solve the problems that a conventional compression-housing method, thought useful, in which one sheet of futon is housed in a compression bag, air in the compression bag is sucked out to compress the bag, and the futon is housed and stored under the compressed state, has a structure wherein bedclothes of this kind is made as the main subject, or one sheet is housed and compressed, does not therefore have a structure wherein a series of bedclothes, a lower futon or a lower pad, an upper futon, a pillow, a lower futon cover, an upper futon cover and a pillow case, are compressed and housed in the compression bag, and is inconvenient for bedclothes as a set.

For this compression-molding method for a set of bedclothes, bedclothes are made into a set, and the bedclothes which have been made into the set are compressed. In the compression-molding method, an internal bag is set in a box equipped with a portable size and a configuration, and the set of bedclothes is folded and housed in order. After the housing, air in the internal bag is sucked out, and the set of bedclothes is compressed. Thus, the compressed set of bedclothes is molded, and the compression-molded compressed set of bedclothes is formed into approximately the same shape as the box and housed in an external bag or an exterior case as the constitution.
