The present invention relates to a bed mattress supported by a spring. More specifically, movement in a transverse direction of the spring for a bed mattress can be blocked, and the spring is embedded in a spring pocket which is only vertically moved to primarily block the spring itself to be moved in a transverse direction. In addition, the spring pocket is fixated by a foam plate placed in the center of a mattress to secondarily block the spring pocket having the spring therein to be moved in a transverse direction. |
