Use of a nonwoven material as underlayer for a fabric for covering seats intended for the transport of people by road, rail or air. …The said nonwoven material is produced by a dry route and has an apparent density of between 20 and 100 kg/m<3> and a thickness of between 4 and 40 mm. The said nonwoven material comprises at least 50 % of synthetic fibres with a thickness of between 3 and 40 dtex and with a length of between 2 and 12 cm. The fibres are bonded by needling.
