Pocket or Bonnell mattress is a choice between two different spring constructions. In the Pocket system, springs are placed in individual pockets, while in the Bonnell system, they are interconnected.
Neither system should be rated solely by name. Comfort is also influenced by spring density, foam and felt layers, mattress height, firmness, and base.
How do Pocket springs work?
Each spring is located in a separate textile pocket and can respond to the load relatively independently. This helps the mattress to conform to body contours and reduce motion transfer.
Pocket mattresses can be very different. The number of springs, zoning, and top layers determine whether the specific model feels soft, medium, or firm.
How does the Bonnell system work?
Bonnell springs are connected in a single block. The load spreads more over the entire structure, creating a traditional springy feel.
These types of mattresses are often simpler and more economical. They may be suitable for a guest bed, rental accommodation or a person who likes a more even, springy surface.
Motion transfer in a double bed
The Pocket system usually better isolates the partner's movements, as the springs are not connected in one block. This can be important if people have different sleep regimes.
On a Bonnell mattress, motion can be more noticeable, but the result is also influenced by the mattress width, people's weight difference, and foam layers.
Base and ventilation
Both types of mattresses require a stable base that meets the manufacturer's requirements. Too large gaps between slats can damage the structure.
A spring mattress must be able to ventilate. Do not cover its underside with unsuitable material and follow instructions for regular rotation.
Examples of Pocket and Bonnell mattresses
Compare two 19 cm high models with different spring system and layer structure.
Amboise Pocket Mattress
Amboise is a firm Pocket mattress with coir layers. Individual springs provide a more individual response to the load.
Agel Bonnell Mattress
Agel uses a Bonnell spring block along with foam and felt layers. It offers a more traditional feel of a uniform spring system.

Frequently asked questions
Is a Pocket mattress always better?
No. It often offers more individual support and less motion transfer, but suitability depends on the entire construction and sleeper's preferences.
Is a Bonnell mattress suitable for everyday use?
It could be if the specific model meets comfort and support requirements. It is advised to try it before purchase.
Should a spring mattress be rotated?
It depends on the model. Follow the manufacturer's instructions for changing the head and foot end or for double-sided use.
Choose the whole construction, not just the springs
Pocket and Bonnell are an important difference, but the final comfort is created by all layers of the mattress. Test the model and check its compatibility with the bed base.
