A coil mattress, commonly referred to as an innerspring or sprung mattress, utilises steel coil springs as the primary support system to offer firmness and body support. These coils, typically combined with various comfort materials like foam, wool, cotton, or latex, cater to different preferences in terms of padding and upholstery.
Types of Coil Systems
Coil mattresses come in various configurations that impact support, motion isolation, and durability:
- Bonnell Coils: These are hourglass-shaped coils interconnected with helical wires, providing mid-priced models with a traditional feel but less motion isolation.
- Continuous Coils: Made of a single continuous wire forming head-to-toe springs, this type offers zoned support and reinforced edges for enhanced durability.
- Marshall Coils: Also known as pocket springs, these individual coils move independently, reducing motion transfer and offering personalized support with pressure relief benefits.
- Micro-Coils: Smaller coils integrated into comfort layers, sometimes in a coil-on-coil design for added support.
Open Coil vs. Pocket Coil Comparison
| Aspect | Open Coil (e.g., Bonnell) | Pocket Coil (e.g., Marshall) |
|———————|————————————–|————————————|
| Spring Connection | Interlinked by wires | Individually encased |
| Motion Isolation | Poor (transfers movement) | Excellent (independent) |
| Support Style | Even weight distribution, firmer feel | Zoned, body-contouring |
| Spring Count (Double)| ~300 | Higher (varies) |
| Cost | Lower (mass-produced) | Higher |
History and Popularity
Coil mattresses were introduced in the 19th century and remain prevalent in the UK and US due to their cost-effectiveness and long-lasting nature. Open coil varieties are particularly common in the budget segment, reflecting their popularity.
Practical Implications and Performance
- Pros: Coil mattresses are affordable, lightweight, provide firm support ideal for orthopaedic needs, and are durable for mass production.
- Cons: Issues may include motion transfer, potential pressure points due to less contouring, the “roll-together” effect, and a bouncy feel.
- Usage Tips: Best for single sleepers or those on a budget, coil mattresses should be rotated quarterly for even wear. Matching them with breathable toppers can enhance overall comfort.
Risks and Considerations
While there are no significant safety hazards unique to coil mattresses, general considerations include potential motion disturbance for couples, sagging in lower-quality models over time due to their interconnected design, and allergens present in fillings like fibers.
Legal Framework in the UK
The legal framework in the UK for coil mattresses mainly adheres to general consumer laws outlined in the Consumer Rights Act 2015 and fire safety standards such as BS 7177. Specific regulations or standards exclusively for coil mattresses are not extensively detailed in available sources post-2020. For precise guidance on compliance and regulations, it is advised to directly consult with UK Trading Standards or the British Standards Institution.
In summary, coil mattresses offer a range of options with varying support and motion isolation features. Consumers should consider their preferences and needs while also understanding any legal requirements to make informed decisions when purchasing a coil mattress.
