Standard pocket coil mattresses rely on single-strand steel wire. While single-strand coils offer baseline motion isolation, they can suffer from metal fatigue, localized sagging, and inadequate support under heavier weight profiles over time.
Slumberzone New Zealand engineered the Tripedic Pocket Spring system to eliminate these structural limitations. Instead of a single wire strand, each Tripedic coil is crafted by braiding three high-tensile steel wires together into a unified helix. This triple-wire design fundamentally changes how a mattress responds to body weight and pressure.

The Science of Triple-Braided Coils
- 10x Structural Strength: Interweaving three steel strands increases load distribution and tensile strength, delivering up to 10 times the durability of standard single-wire pocket coils.
- Progressive Support Mechanics: The braided wire configuration provides a non-linear support curve. Light pressure encounters soft initial comfort, but as heavier force is applied, the braided strands engage collectively to deliver firm, uplifting resistance.
- Dynamic Controlled Rebound: Motion energy and vibration dissipate across the three interwoven wires rather than bouncing back up, virtually eliminating partner disturbance and erratic recoil.
- Targeted Tripedic Zoning: Scientifically arranged into a dedicated Tripedic Zone within the mattress layout, these coils provide extra reinforcement beneath high-stress areas like the lower back and hips.
| Feature | Standard Pocket Coil | Slumberzone Tripedic Coil |
| Wire Construction | Single solid strand | Braided triple-wire strand |
| Relative Strength | Standard baseline | 10x structural integrity |
| Weight Adaptation | Fixed linear resistance | Progressive dynamic resistance |
| Lumbar Support | Uniform grid | Boxed targeted Tripedic Zone |
| Sag Resistance | Susceptible under heavy load | High resistance to metal fatigue |
Primary Applications
- Heavier Weight Profiles: Built specifically to support higher weight capacities without bottoming out or compromising posture.
- Targeted Lumbar Alignment: Prevents mid-body sinkage, ensuring the spine remains neutrally aligned throughout all sleeping positions.
- Disturbance-Free Partner Sleep: Combined motion isolation from pocket encasements and energy absorption from braided wire construction.
Slumberzone’s Tripedic Pocket Spring system offers an optimal balance between surface cushioning and structural longevity delivering heavy-duty support engineered specifically for long-term spinal health.
