What 19th-century invention enabled better support and mass production?

Answer

The coil spring mattress

The structure of bedding underwent a significant mechanical transformation during the era characterized by industrialization, specifically in the 19th century. The key innovation that revolutionized support and accessibility was the coil spring mattress, which received its patent around the year 1840. By incorporating resilient metal coils into the mattress core, manufacturers could achieve much greater consistency in support and superior shape retention compared to earlier stuffed materials like hay or feathers. This standardized construction method was crucial as it facilitated mass production, allowing high-quality support to become available to a broader segment of the population beyond only the elite classes.
