The invention aims at providing beddings which are made by using wadding containing polyester excellent in elasticity and which exhibit such high-grade flame retardance as to withstand long-time flaming even when the content of a halogen-containing fiber in the wadding is small. The aim can be attained by a flame-retardant bedding composed of wadding and a tick covering the wadding wherein the wadding comprises a cellulose fiber (A), a polyester fiber (B) and a halogen-containing fiber (C) as the essential components. The beddings of the invention are excellent not only in flame retardance but also in cushioning properties because they can contain large amounts of a polyester fiber by virtue of the use of relatively small amounts of a halogen-containing fiber. Since the beddings exhibit satisfactory flame retardance even when a flammable fabric such as polyester or cellulose fabric is used as the tick, the invention can provide beddings excellent in feeling and touch as well as in flame retardance.
