Differences between pocket spring, open coil, bonnell coil and IPS3


Our Unique Spring - Individual Pocket Spring Suspension System

Lifetime: 9/10

Support: 9/10

Price value: 8/10

Hypoallergenic: 9/10

Pocket springs are individually wrapped coil systems that are stitched into mattresses below a comfort layer of foam, latex or even coconut fibers. Unlike traditional innerspring systems that are interconnected, pocket springs are entirely independent allowing for zoning and pressure point relief than older innerspring models.

The general rule on pocket coil systems is the more coils, the more responsive and motion controlled the mattress is, while still providing support. This directly translates to more comfort. However, too many coils will result in an huge price tag to the mattress of interest.

In most pocketed spring beds, there is a layer of memory foam or latex above the pocket spring array so that the sleeper gets both the benefits of contouring foam and the comfort of the pocket springs.

Pros: Durable materials and superior comfort

Cons: Sleepers should be equally as interested in the foam that is wrapped around the coil system - if that is low quality, the bed still may be uncomfortable. More costly than interconnected springs.

Our IPS3 mattresses can last more than 12 years.

Pocket spring

Popular choice by many

Lifetime: 9/10

Support: 9.8/10

Price value: 8.4/10

Hypoallergenic: 9.8/10

Pocketed spring mattresses offer more support than open coiled. The individual springs that make up the mattress are housed in their own little pockets and work independently of each other. Spring counts can vary dramatically from 600 to 3,000. Typically, the higher the spring count, the better the support and so is the price tag.

Pros: Because the springs move independently they offer more support for your body, and are ideal for two people of different weights as individual pocket-spring mattresses allows isolation prevent disturbance of the partner when turning during sleep.

Cons: Product is relatively heavier, due to the density of their fillings.

If you suffer from allergies, be sure to check the fillings carefully, as many use natural materials like lambs wool and natural latex, which can aggravate allergies.

Pocket spring mattresses can last between 7-12 years.

Open coil

Lifetime: 6/10

Support: 8.7/10

Price value: 9/10

Hypoallergenic: 9.6/10

Open coil (also known as Miracoil, Continuous coil, Standard coil e.t.c) are the most common types of mattresses, which consist of an inter-connected spring system. They are the traditional manufacturing method, capable of being mass-produced with a low production cost – this makes them one of the cheapest on the market. A standard open coil mattress contains an average of 300 springs.

Pros: Open coils provide excellent support and are used for most mattresses due to their firmness. They tend to have more ‘give’ than pocket sprung mattresses, and are lighter and therefore easier to flip.

Cons: Not as robust as other mattresses and can be known to ‘dip’ or 'sag' in the middle after prolonged use. Open coiled bedding can also lead to the ‘roll-together’ feeling for couples, and you will feel the movement of your partner.

These are great mattresses for children, lasting between 3-5 years

Bonnell Spring

Competitive price

Lifetime: 5/10

Support: 6/10

Price value: 9/10

Hypoallergenic: 8/10

Bonnell spring mattress systems are the most traditional type of innerspring mattress. The Bonnell coil has an hourglass shape (wider at the bottom and the top than the middle) and is interconnected with a mesh of metal to make the spring system.

In many traditional innerspring mattresses and still some entry level models today have used the Bonnell spring to create cheap supportive mattresses. Though this system is good at providing even support, there has been complaints of aggravated pressure points and discomfort with Bonnel spring systems.

Pros: Durable materials and traditional even feel.

Cons: Pressure point discomfort and motion transfer issues.

Bonnell spring mattresses can usually last between 1-3 years.
