Pocket springs are arranged as spring structures 10 on the outer sides of the pair of outer frames 14 so as to be overlapped with the outer sides of the inner springs 11 to form side walls 13).

Herein, it is previously described that the pocket spring is referred to as a first pocket spring 12 to prevent confusion since the same terminology is used in the following.

The bonnel springs 11 are coupled to the outer frame 14 via the binding clip 16 and are coupled to each other via the binding coil 15. That is, each of the bonel springs 11 are coupled to each other via the coupling coil 15, and the inner shell 14 and the inner spring 14 adjacent to the outer frame 14 are fastened to the outer frame 14 via the fastening clip 16, Respectively.

The binding coil 15 is wound around the inner spring 11 in the form of a coil so as to be coupled to each other, thereby preventing the displacement and correcting the elastic force.

Therefore, according to the embodiment of the present invention, the bellows springs 11 having excellent elasticity are arranged longitudinally and transversely in the inner space of the mattress 1, so that the restoring force against the center of the mattress 1 can be enhanced . The first pocket springs 12, which act independently of each other, are arranged on the outer periphery of the mattress 1, so that the whole of the edge where the pressure or impact is concentrated due to the action of, for example, It is possible to prevent a deflection phenomenon.

In addition, the first pocket spring 12 is easy to replace due to its characteristics and is also effective in terms of maintenance of the mattress 1.

The mattress 1 according to an embodiment of the present invention includes a first pocket spring 12 and a nonwoven fabric 30 surrounding the outer surface of the bonel spring 11 and a sheath 20 surrounding the nonwoven fabric 30 do.

For example, the outer skin 20 may be made of a fabric material having excellent air permeability to facilitate sweat absorption during body contact, and may have various shapes of decorative or embroidery patterns on its surface.

Such a covering 20 is formed by applying a conventional flame retardant which can be applied, for example, with silicone, a silicone composition or a phosphoric acid compound to the covering 20 and coating the covering material, or by impregnating the fabric material constituting the covering 20 with a flame retardant .

The nonwoven fabric 30 protects the outer surface of the spring structure 10 and protects the spring structure 10 from being released to the outside. Then, the air is allowed to flow, but dust or foreign substances entering from the outside are blocked.

That is, the nonwoven fabric 30 has a lower risk of fire than a sponge that can be referred to as foam commonly used in the mattress 1, and is excellent in terms of management because of its excellent fluidity of air.

Here, the nonwoven fabric 30 is coated with a conventional flame retardant to the nonwoven fabric 30 in the same manner as the covering 20, or the nonwoven fabric 30 is flame-treated by a method of impregnating the nonwoven fabric 30 with a flame retardant.

Therefore, according to the embodiment of the present invention, the risk of fire of the mattress 1 can be easily lowered through the flame-proofing sheath 20 and the nonwoven fabric 30, which is effective in improving the reliability of the consumer.
