<p>PROBLEM TO BE SOLVED: To provide a futon which can make an in-bed environment comfortable in a short time by quickly increasing an in-bed temperature, keeping a warm condition for a long time, and keeping an in-bed humidity constant.SOLUTION: A futon of the invention includes: a cotton layer of ultrafine fibers 7 which can quickly exude moisture absorbed by a cotton layer of hygroscopic heating fibers 3; heat storing and insulating fibers 5 which can increase a temperature of an in-bed environment more quickly than ever before and can keep a warm condition longer than ever before by efficiently storing heat from the skin: and the cotton layer of the hygroscopic and heating fibers 3 which can quickly absorb moisture generated by perspiration of the skin and can increase the temperature of the in-bed environment by heat generated in absorbing the moisture, more quickly than before.</p> |
