Claims

[Scope of utility model registration request]

A spring unit formed into a rectangular plate shape by connecting a number of springs, an elastic material polymerized on at least the upper surface of the spring unit, and an exterior covering covered with a polymer of the elastic material and the spring unit. In the constructed mattress, the spring unit includes a first section to a fourth section consisting of a plurality of spring rows along the longitudinal direction.
The spring located in the second region is more elastically deformable than the spring located in the first region, and the spring located in the third region is more easily deformed than the spring located in the second region. A pinerest characterized in that the spring located in the fourth region is more easily deformed elastically than the spring located in the third region.
