What is a pocket sprung mattress?
Posted by Coast Road Furniture on
A pocket sprung mattress contains individual springs enclosed within separate fabric pockets. Each spring can respond to pressure more independently than the connected springs used in a traditional open-coil mattress. This allows the mattress to adapt more closely to the sleeper while reducing how much movement travels across the bed.
Pocket springs form the supportive core of the mattress. The materials above them (such as wool, cotton, foam or other upholstery) help determine its overall comfort, firmness and temperature regulation.
How Does a Pocket Sprung Mattress Work?
When you lie on a pocket sprung mattress, the springs beneath the heavier parts of your body compress more than those supporting lighter areas. This creates a more individual response across the sleeping surface instead of the entire spring unit moving together.
Although the springs are contained in separate pockets, they are still part of a complete mattress. The fabric pockets, surrounding upholstery and mattress cover all influence how responsive and supportive the finished mattress feels.
What Are the Benefits of Pocket Springs?
- Responsive support: Individual springs can react more closely to differences in pressure across the body.
- Less movement between partners: Movement is generally less likely to travel across the whole mattress than with a connected open-coil system.
- A choice of comfort levels: Pocket sprung mattresses are available in softer, medium and firmer options.
- Suitable for different fillings: Pocket springs can be combined with natural upholstery, foam, gel and other comfort materials.
- Useful for couples: Some models are available with different tensions on each side. Find out more in our guide to split-tension mattresses.
Pocket Sprung vs Open-Coil Mattresses
| Feature | Pocket Sprung | Open Coil |
|---|---|---|
| Construction | Individual springs in separate fabric pockets | Springs connected within one unit |
| Response | More individualised response to pressure | Broader movement across the spring system |
| Partner disturbance | Generally reduced | Movement may travel more easily |
| Typical price | Usually mid-range to premium | Usually more affordable |
Open-coil mattresses can still provide practical, comfortable support, particularly for occasional-use beds or tighter budgets. However, pocket springs are often worth considering when the mattress will be shared or used every night.
Does a Higher Pocket Spring Count Mean a Better Mattress?
Spring count is useful, but it should not be considered on its own. Counts are usually quoted using a king size mattress, and very high figures may include several layers of smaller springs or microsprings.
A higher number does not automatically make a mattress firmer or more supportive. Spring quality, spring tension, mattress upholstery and suitability for your body are equally important. Two mattresses with similar spring counts can feel completely different when tried in person.
Some manufacturers use more advanced spring arrangements in their premium models. Our guide to whether Harrison Spinks mattresses are worth the investment explains how one British manufacturer approaches pocket spring construction.
Are Pocket Sprung Mattresses Firm?
Pocket sprung does not describe a particular firmness. The springs can be manufactured in different tensions and combined with soft, medium or firmer comfort layers. A pocket sprung mattress can therefore feel gently cushioned, supportive and firm, or somewhere between the two.
The best tension depends on factors including body weight, sleeping position, comfort preference and whether the mattress is being shared. Firmness labels can also differ between manufacturers, which is why trying a mattress is useful whenever possible.
Natural Fillings, Foam and Hybrid Options
The comfort layers above the springs can be just as important as the spring unit itself. Natural materials such as wool and cotton are often chosen for their breathability, while foam layers can provide more noticeable cushioning and pressure relief.

Is a Pocket Sprung Mattress Right for You?
A pocket sprung mattress may be particularly suitable for couples, restless sleepers and anyone who wants responsive support without relying entirely on foam. However, the spring count and specification cannot tell you exactly how comfortable a mattress will feel.
