How did the invention of the coiled spring in 1871 change mattress technology?

Answer

It allowed for consistent weight distribution and longer lifespan for the sleeping surface

Before the introduction of coiled springs, mattresses were primarily bags filled with loose natural materials like straw, hay, or feathers. These materials were prone to clumping, shifting, and degrading, which resulted in an uneven sleeping surface over time. Coiled springs introduced a mechanical solution that provided consistent support across the entire surface, effectively creating a more durable and comfortable product that lasted significantly longer than previous stuffing-based models.
