Series and parallel springs

Series and Parallel springs are used to help support a heavy load like a bed. When two or more springs are connected in series, it means that the springs are connected one after the other in a single line. Because the springs are connected one after the other, the load will be shared evenly across all the springs in the series. This means if you put a heavy load on the springs, the load will be shared evenly across the springs, making it easier to support the weight.

When two or more springs are connected in parallel, the springs are connected side-by-side. With springs connected in parallel, the load will not be shared evenly. If a heavy load is placed on the springs, the heavier springs will bear the majority of the load while the lighter springs will bear less. This allows the springs to work together to support a larger load than if they were connected in series.
