Method and apparatus for quickly, and substantially uniformly, heating and cooling a bed of polymeric fibres (10) having high melting-point and low melting-point fibres therein for softening the low melting-point fibres and bonding them to the high melting-point fibres to form a seat cushion. Hot and cool gases are flowed through the bed of fibres (10) to effect the heating/cooling. <IMAGE> |
