Abstract
An upholstered comfort member, comprising a resilient comfort material and a cover fabric. The resilient comfort material comprises lignocellulosic fibres, which provides resilient properties to the resilient comfort material, and a binder at a concentration of between 1 and 30 wt %. The binder binds the lignocellulosic fibres together. The invention further relates to a method for manufacturing of such an upholstered comfort member.

A method for manufacturing a resilient comfort material comprising lignocellulosic fibres providing resilient properties to the resilient comfort material, and a binder at a concentration of between 1 and 30 wt %, the binder binding the lignocellulosic fibres together and wherein the binder is a bi-component binder fibre, wherein the method comprises the steps of:
- mixing lignocellulosic fibres and bi-component binder fibre
- whereby a mixture of lignocellulosic fibres and binder comprising between 1 and 30 wt % of the binder is obtained;
- transporting the mixture through a roller into an oven;
- subjecting the mixture to heat in the oven such that the binder
- partly melts and binds the lignocellulosic fibres together;
- and
- extracting the formed resilient comfort material from the oven.
