What Is Bonnell Spring Mattress? A Simple Guide to This Classic Mattress Type
If you’re searching “What Is Bonnell Spring Mattress”, you’re likely trying to understand what this mattress type is, how it feels, and whether it might suit your sleeping needs. This guide explains the basics in clear, practical terms so you can compare it with other mattress materials more confidently.
What Is a Bonnell Spring Mattress?
A Bonnell spring mattress is a type of innerspring mattress that uses hourglass-shaped metal coils connected together in a network. These coils form the support core of the mattress, usually topped with layers of foam or fabric for comfort.
Key features of Bonnell springs:
- Hourglass shape: Wider at the top and bottom, narrower in the middle
- Interconnected design: Coils are tied together with metal wires
- Uniform support: The surface tends to feel consistent across the mattress
When people ask “What Is Bonnell Spring Mattress”, they’re usually trying to distinguish it from pocketed spring mattresses, foam mattresses, and hybrid designs. Bonnell springs are known as a more traditional, widely used spring system.
How Does a Bonnell Spring Mattress Feel?
Firmness and support
Bonnell spring mattresses often feel medium-firm to firm, depending on:
- The thickness (gauge) of the coils
- The number of coils
- The comfort layers (foam, fiber, or quilting) added on top
The interconnected coil system usually gives a bouncier, more responsive feel than many foam mattresses. Some sleepers appreciate this for easier movement and a “sleeping on” rather than “sleeping in” sensation.
Motion and pressure
Because all the coils are linked:
- Motion can travel across the bed more easily than in individually wrapped coil systems.
- Pressure distribution is more general, rather than deeply contouring to each curve of the body.
Many users experience Bonnell spring mattresses as supportive but less conforming than memory foam or other body-hugging materials.
What Are the Main Pros and Cons of Bonnell Spring Mattresses?
Here’s a quick side-by-side overview:
| Aspect | Potential Advantages | Potential Drawbacks |
|---|---|---|
| Support feel | Firm, stable, traditional spring feel | Less contouring to body curves |
| Responsiveness | Bouncy, easy to move on | Motion can transfer across the surface |
| Temperature | Generally good airflow through open coils | Comfort depends heavily on the top layers |
| Durability | Simple, time-tested structure | Over time, some users may notice sagging areas |
| Price category | Often found in more budget-friendly ranges | Fewer advanced comfort features than newer types |
These are general tendencies; individual mattresses can vary based on materials and construction quality.
How Is a Bonnell Spring Mattress Different from Other Spring Types?
Bonnell vs. Pocket Spring
- Bonnell spring: Coils are interconnected. Movement on one side can be felt on the other. Support feels more uniform.
- Pocket spring: Each coil is individually wrapped. This can help reduce motion transfer and allow more targeted support.
When people search “What Is Bonnell Spring Mattress”, they often want to know whether it is “worse” or “better” than pocket springs. It’s more accurate to say:
- Bonnell systems are simpler and more traditional
- Pocket systems are generally designed for more individualized support and motion isolation
Bonnell vs. Foam
- Foam mattresses typically contour more closely to the body and absorb motion.
- Bonnell spring mattresses provide a more springy, ventilated feel with less body-hugging.
Who Might Consider a Bonnell Spring Mattress?
While preferences vary, a Bonnell spring mattress may appeal to:
- Sleepers who like a firmer, traditional spring feel
- Those who prefer more bounce and easier movement on the bed
- Shoppers looking in lower to mid price ranges
- People who tend to sleep warm and appreciate some airflow through the mattress core
On the other hand, people who prioritize deep contouring, targeted pressure relief, or strong motion isolation often gravitate toward foam or pocket spring options instead.
What Should You Look for in a Bonnell Spring Mattress?
If you’ve decided that a Bonnell spring design might fit your preferences, a few details can help you compare options:
1. Coil count and gauge
- Coil count: A higher number of coils within the same size can sometimes indicate finer tuning of support.
- Coil gauge: Thicker coils (lower gauge number) usually feel firmer and more robust; thinner coils often feel softer.
2. Comfort layers on top
The top layers have a major impact on how a Bonnell spring mattress feels:
- Quilted fiber or foam for cushioning
- Additional foam layers for extra softness or contouring
A supportive coil unit with too thin a comfort layer may feel very firm or allow you to feel the springs more quickly over time.
3. Edge support
Some Bonnell mattresses reinforce the edges with stronger coils or extra structure. This can help the sides feel more stable when sitting or lying near the edge.
✔️ Quick Mattress Takeaways
Key points consumers should understand about “What Is Bonnell Spring Mattress”
- A Bonnell spring mattress uses hourglass-shaped, interconnected coils as its main support system.
- It generally offers a firm, bouncy, traditional innerspring feel rather than deep body contouring.
- Motion from one side of the bed can travel across the surface more than in many pocket spring or foam designs.
