Abstract of the Disclosure A bedding unit spring has an upper portion attached to a grid, a lower portion attached to a frame, and a vertically collapsible midportion which connects the upper portion to the lower portion. The upper portion of a spring may have two transverse bars at its ends, a third transverse bar at its center, and a center bar formed of two sections which are on opposite sides of the third transverse bar. The center bar sections are directed toward the midportions of the end transverse bars. A deflection limiter member is attached to the spring to limit the collapsing movement of the spring and to increase the effective stiffness of the spring. It is formed of a wire which has an abutment portion and two connector bar portions. The connector bar portions extend at different inclination angles from the abutment portion to the spring. In embodiments where the ends of the spring wire are located in the upper portion of the springs the lower portion has a foot which in connectible to the frame, and the midportion has two lower connector bars which extend outwardly from the foot in opposite directions. The upper portion has two spaced apart center bar sections directed toward the midportions of two transverse bars, the latter being located either between or on opposite sides of the center bar sections. In versions where an end of the spring wire is in the lower portion of the spring, the spring has a foot which is insertable and lockable in a hollow metal slat. The end of the spring wire is at the trailing end of the foot during insertion. When this trailing end passes beyond the slot it moves resiliently outwardly to a position where it confronts the interior surface of the slot to lock the foot in position.
