What Are Pocket Springs? History and How to Choose
Pocket springs are the core of a pocket coil mattress, popularized after Simmons invented a mass-production machine in the US in 1925. Each spring is individually wrapped and moves independently, supporting the body evenly — the mainstream structure of modern mattresses.
Pocket springs are the heart of every pocket coil mattress. They only became widespread after Simmons in the United States invented a machine capable of mass-producing individually wrapped coils in 1925 — and because different parts of the world discovered Simmons at different times, sleep habits evolved differently from place to place.
Take Taiwan as an example. People here traditionally slept on hard beds, so even with Simmons' long history, it could not fully change Taiwanese sleeping habits. Interestingly, though, once Taiwan's economy took off, the phrase 'sleep quality' started to matter, and Taiwan's furniture industry was smart enough to refine and adapt the pocket spring mattress to suit local sleepers. Over the past decade in particular, with information so readily available, consumers now look well beyond simple firmness or durability when choosing a mattress — they care about comfort, support, contouring, and functionality.
Drawing on our many years of experience selling mattresses, we hand-picked the designs best suited to the Taiwanese market and refined them further, combining the scientific craftsmanship of imported premium brands with Taiwan's own down-to-earth spirit to create the Formosa series, which offers the following features:
A solid, stable pocket spring structure for greater durability and support — no worries about the feel changing over the years; any change is slow and gradual, and the springs resist fatigue extremely well
Bouncy, body-hugging latex that adds softness without ever tipping into too-soft territory
A soft, comfortable cotton-feel surface finished in refined, understated high-weight fabric
On a firmness scale where 1 is extra firm and 10 is extra soft, the Formosa series sits in the 3–5 range — a good match for how most people in Taiwan like to sleep, and the safest, most reliable choice for anyone buying their first pocket spring mattress.
