Coil Mattress Types
There is no perfect coil system for everyone. Each person has their own preference. Some prefer the response of a bonnell style coil; an hour glass shaped coil that has been around for decades. Still others like the solidity and durability of a continuous coil system. The often hyped pocketed coil system is another option that has some real benefits too. Here is a little info on what makes each style work and some hints as to which might be best for you. Included is an expected budget for each style of support. Above this price range, you should consider a superior support system like latex. Below this price, you may be sacrificing quality.
POCKETED COIL SYSTEM
Pocketed Coil System is a grouping of independent coils wrapped in a fabric casing and joined together with either glue, fabric or thread. Depending upon the tempering and gauge of the coil, you can expect a broad range of durability. As a system it conforms better to your body than other styles of coil. It's terrific for pressure point relief if you are a side sleeper (60% of people are). It also dampens the transfer of motion. Therefore, movement does not disturb sleeping partners as much. The down side of this style of coil is that it is less durable if one is above average weight. More wear and tear is put on the coils where you are the heaviest, and therefore the foam directly below you. Body impressions are very common with this style of mattress, especially when the product is not on a solid foundation. Being able to vary the coils that you sleep on will maximize the life of this support system.
Budget $799-1599 for a Queen Set.
CONTINUOUS COIL SYSTEMS
Continuous Coil Systems are durable and responsive. They consist of many coils that are literally one piece of connected metal and give firm support for any size person. By keeping each coil connected, every spring is able to draw support from the adjacent coils and combine comfort with durability. A medium gauge coil is often used to allow for gentle give while maintaining longevity. One drawback is the lateral transfer of motion. This is addressed somewhat through running the strands of coils from head to toe rather than side to side. If you need firm support, but want to avoid the transfer of motion completely, look at latex mattresses. That said, the continuous coil system is a good lower cost alternative.

BONNELL COIL SYSTEMS
Bonnell Coil Systems are made in many gauge and coil counts and levels of durability. Here are some tips for finding a long lasting product. Consider the coil count. In a full size look for a minimum of 500 coils for an adult unless you have a very heavy coil ; 13 or less. A count of 312 is great for kids and will be durable in most gauges. Do not buy if it is less than that as you$ll end up replacing it sooner than wished. Gauges of 13-16 are common. The lower the number, the heavier the coil and firmer the support. Lighter gauges can still be durable, but you need very high coil counts. Transfer of motion is also an issue with this style of coil, but it is much less expensive than the alternatives.
Budget $449-899 for a Queen Set.
DOUBLE OFFSET COIL SYSTEMS
Double Offset Coil Systems are slightly more conforming than the bonnell and continuous coils and are essentially the same in function. This system is relatively equal in durability and comfort to the continuous coil system. The most likely portion of these mattresses to fail is the foam on top, not the coils themselves. Coil count rules still apply here, but you can expect a nice firm support and if it is flippable, it is a durable product. As with all coil mattresses, two sides are better than one.
Budget $699-1299 for a Queen Set.
Bear in mind that the suggested budgets are merely a guide and that more and less expensive options will be out there. If you choose to spend less, you will end up with a bed that won't last you ten years or more. Just because something is on sale does not make it a bargain!
