ABSTRACT:
There is provided an innerspring assembly used in a mattress for absorbing external loads. An outermost coil spring115of a spring array110is secured in a space between upper and lower border wires120and120′by pins140, and helical coils130are disposed in row directions R on upper and lower portions of the spring array110to knit an adjacent coil spring115, such that each coil spring has a free terminal convolution115aprotruded from an upper portion of the upper border wire120and/or a lower portion of the lower border wire120′. The spring assembly includes an enclosure10partially or fully provided on an upper end portion and/or an lower end portion of the coil spring for covering the terminal convolution115ain the row direction R or column direction L, thereby interrupting interference between the terminal convolution115aand the upper and/or lower border wire120and120′and absorbing a lateral load applied to the terminal convolution. A padding member is not damaged by the terminal convolution, and a contact resistance between the upper border wire and the terminal convolution is absorbed to block a frictional noise.
