A Bonnell Spring Mattress uses a connected metal spring unit. Understanding how the unit is built helps you read mattress descriptions accurately and compare models on their actual construction rather than on broad claims.
How the Bonnell spring unit is built
Bonnell coils are typically hourglass-shaped and linked together with connecting wires to form a shared spring unit. Because the coils are connected, pressure on one area can influence nearby areas. The final feel of a mattress depends on more than the spring unit alone: padding, quilting, foam layers, the cover and the overall design also matter.
What to compare before choosing
- Confirm the exact mattress dimensions and height option.
- Read the listed comfort layers and materials for that specific model.
- Consider whether you prefer the response of a connected spring system.
- If you share the bed, compare how the full construction handles movement; do not judge this by the spring name alone.
- Review warranty terms and care instructions.

Bonnell Spring and “orthopedic” are different terms
“Bonnell Spring” describes the connected spring system. “Orthopedic” is a product category or positioning term and does not, by itself, prove that a mattress treats or prevents a medical condition. A product can use Bonnell springs and also be listed in an orthopedic range; check the specific product specifications.
Is Bonnell the same as Pocket Spring?
No. Bonnell coils are connected into one unit, while Pocket Spring coils are individually enclosed in fabric pockets and can respond more independently. Read our Bonnell Spring vs Pocket Spring comparison for a side-by-side explanation, or browse the Pocket Spring collection.
