A process has been devised for restoring full-sized innerspring mattresses by removing the end of the mattress cover to expose the coils, inserting resilient blocks of material into the spaces between adjacent rows of coils whereby to extend the full length of the mattress, and reclosing the mattress cover. A special form of resilient block is employed which is of graduated firmness, and an insertion tool greatly facilitates insertion of the blocks for the full length of ther mattress, following which the tool can be removed.
