Double stacked springs?

How can you stack a 400# spring on top of a 200# spring and it is noticabley softer. Approx 150# rate.

A weight doesn't tell you much about a spring, and the only soft spring I can think of is a sponge.

An ideal spring exerts a force proportional to its displacement, F = -kx. If you apply the same force to a stacked pair of springs, the total displacement will be the sum of the displacements each spring would exhibit independently. The effect is a smaller value for the spring constant k. Perhaps this is what you're thinking of.
