Detailed Description

The invention will be further described with reference to specific embodiments. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

The present invention will be further explained with reference to the drawings and examples.

As shown in fig. 1 to 4, the bamboo spring sofa cushion comprises a cushion cover 1 and a cushion body, wherein the cushion cover 1 is sleeved outside the cushion body. The cushion cover 1 can be made of cotton cloth, real leather or microfiber artificial leather.

The seat cushion body comprises a sponge outer cladding layer 6 and an elastic layer, and the sponge outer cladding layer 6 is wrapped on the outer side of the elastic layer.

The elastic layer comprises a bamboo spring matrix and a first non-woven fabric layer 2, and the first non-woven fabric layer 2 is wrapped outside the bamboo spring matrix.

The bamboo spring matrix is formed by arranging a plurality of independent non-woven fabric bagged bamboo springs according to a matrix, and each non-woven fabric bagged bamboo spring is composed of a bamboo spring 4 and a second non-woven fabric layer 3 wrapped on the outer side of the bamboo spring 4. Adopt the solitary bamboo spring of non-woven fabrics parcel, every bamboo spring can atress alone, lets the atress more even, has reduced the friction between each spring, has eliminated the noise that the friction produced, makes the seatpad have the effect of silence, has also prolonged the life of seatpad simultaneously, provides soft comfortable sitting and sleeping experience for the people of different sizes.
