AbstractFull‐scale fire tests on domestic beds fully equipped with bedding materials have been carried out in an experimental compartment‐corridor facility at the Fire Research Station, Borehamwood, U. K. Mattresses made of hair, spring interior, foam rubber and polyurethane of various types, together with mattress covers of cotton, flame‐retarded cotton or proofed nylon were studied. The effectiveness of protective hair or glass fibre interlining was examined. The study has shown that a rapid development of fire in bed and bedding materials can take place with certain combinations of mattresses and their covers. The types of covers extremely important in overall fire development, particularly with polyurethane mattresses. A substantial improvement in the fire behaviour of many of the principal types of beds tested can be achieved by a careful selection of bedding materials, such as the type of mattress cover, and in certain cases by the use of protective interli
