Abstract
A 3-layer venting mattress structure comprised of a steel fiber layer sandwiched by net layers sewn on its periphery. Both upper and lower net layers are made of fiber or non-woven with interlaced mesh for venting purposes. The steel layer between the fiber layers is made of high-strength steel yarn lop-sided woven in a spiral and continuous fashion to provide a mattress that allows excellent air permeability and tensile strength with sufficient capability to withstand local area loads. Therefore, the present invention solves the poor ventilation problem of the prior art, achieves the evenly distributed load susceptibility of the mattress, and provides an innovative type of space arrangement.
Claims2
A multi-layer, ventilating cushion material comprising:
- a) a first layer of steel fiber formed in a continuous spiral, the first layer having upper and lower portions;
- b) an upper layer of mesh fiber material having pores to facilitate air circulation therethrough, the upper layer being interlaced with the upper portion of the first layer;
- and,
- c) a lower layer of mesh fiber material having pores to facilitate air circulation therethrough, the lower layer being interlaced with the lower portion of the first layer.
