Mattress

The utility model relates to a mattress. The supporting performance of all areas of the existing mattress is consistent, and the partition use requirement cannot be met. The mattress comprises a mattress body, the mattress body comprises at least three subareas which are sequentially divided from front to back, and every two adjacent subareas are respectively formed by double-layer equal-height springs or double-layer unequal-height springs, so that the double-layer equal-height springs and the double-layer unequal-height springs are alternately arranged and spliced to form the mattress body. The double-layer equal-height spring bodies or the double-layer unequal-height spring bodies with the differentiated multi-layer supporting performance are arranged in the adjacent subareas respectively, so that the subareas can provide adaptive supporting for the corresponding body sections of the user, it is ensured that the body sections of the user can obtain comfortable supporting, and the using comfort is improved.
