​Innerspring mattresses provide support through the use of steel coils. The actual number of coils is less important than the method used in their production. There are four different types of

commomly used coils.


Bonnell Coil Innerspring


This hourglass shaped coil is the oldest and still one of the most common in use today. They remain popular because of the low production costs. They are connected head to toe with helical wire and are less responsive than pocketed coils. If you have a sleep partner, you will also be more aware of their movement. Bonnel coils are not adjustable base friendly.


Offset Coil Innerspring


Offset Coils are hourglass Coils that have portions flattened at the top and bottom. The flattened portions are then hinged with helical wires. This hinging process make them more conforming. These units make less noise than than Bonnell Coils. Yet, motion transference is still an issue. Like Bonnel coils, Offset are not adjustable base friendly.


Pocketed Coils Innerspring


Pocketed Coils, (shown in above picture) are individual hourglass coils wrapped in fabric. This barrel shaped design is often referred to as a Marshal Coils. Their design allows for more motion separation than the Bonnell or offset coils. Individual coils are not connected and provide greater flexibility. Unlike Bonnell coils, Pocketed coils are suitable for adjustable bases. This style of innerspring is the standard in better quality coil beds.


Continuous Coil Innerspring


Continuous Coils are rows of coils each made from a single wire and shaped in a unique S shaped design. These coils are interlinked for durability. Serta Perfect Sleeper beds use this particular coil. It’s worth noting that their upper end I Comfort series upgrades to a pocketed coil. Like Bonnel and Offset coils, they are not suitable for adjustable beds.


Pros:

​​Innerspring mattresses are found in both brick & mortor stores as well as online. At least in the initial stages, they have better than average support potential. Edge support is more substantial than latex or memory foam.



Cons:


Sagging is a huge concern with Innerspring beds. Type, density and quantity of the coils affect durability and longevity of a mattress. Innersprings fare worse than spring free competition in both comfort and durability. Research has shown Innerspring beds grading at an uninspiring 67% customer satisfaction rate.


Conclusion:


Innersprings are the most common mattresses sold throughout the US. These affordable beds are available almost everywhere. The emergence of memory foam and latex beds has introduced more consumer alternatives. Still, innerspring mattresses remain solid options at reasonable prices.


Hybrid


The term “Hybrid” gets tossed around a lot in the bedding industry these days. It’s an enticing catch phrase that marketers have presented as a new and exciting option. The truth is, there is not a whole lot of ground breaking advances here to talk about. Webster’s Dictionary defines "Hybrid" as something formed by combining two or more things. Hybrid mattresses combine traditional innerspring (usually pocketed coil) with Memory foam or Latex. This term describes a pretty large percentage of quality mattresses sold these days.


Pros:


Better quality foams add more conformity and pressure relief than standard innerspring offerings. They also tend to rank higher in customer satisfaction surveys.


Cons:


Cost of these beds jump considerably due to the expense of the premium foams used. Yet, durability and longevity issues still exist with traditional innersprings.


Conclusion:


Ultimately, these beds are not significantly different from a standard Innerspring mattresses. If they meet your needs for comfort and support, do not rule them out. Having said this, we do caution not to pay too much because of a clever marketing pitch
