The Evolution of Mattress Springs: History, Types & Impact on Sleep

1. History of Mattress Springs

Origin (Mid-19th Century): The first spring mattress was invented in 1857 by German engineer Heinrich Westphal. However, it wasn't until 1871 that Simmons introduced the first industrialized spring mattress, marking the beginning of the modern industry.

Evolution: From the classic Bonnell Spring (late 19th century) to the Continuous Spring (early 20th century), and the revolutionary Pocketed Spring (mid-20th century) which offered independent support. Today, we see advanced Zoned Springs and Micro Springs for precision comfort.

2. Main Spring Types Comparison

Type Features Pros Cons
Bonnell Spring Hourglass shape, connected coils Low cost, strong support Motion transfer, potential noise
Continuous Spring Single wire knitted structure Durable, stable Stiffer feel, motion transfer
Pocket Spring Individually encased coils No motion transfer, contouring Higher cost, weaker edge (if not reinforced)

3. Impact on Sleep & How to Choose

Pocket Spring: Best for couples and side sleepers. It isolates motion so you don't feel your partner move, and contours to relieve pressure points on shoulders and hips.

Bonnell/Continuous: Good for back sleepers who prefer a firmer feel, or for budget-friendly options like guest rooms.

Hybrid Systems: Combining springs with foam/latex layers offers the best of both worlds—support and pressure relief.
