Are you on a budget? => Bonnel coil
Bonnet coils have the simplest coil structure of all innerspring mattresses. These mattresses are also known as open coils and are made of hourglass-shaped coils made of steel. The coils are designed to be thinner in the middle so that they can be squeezed together with soft pressure.
This simplicity translates into a much lower cost than other innerspring mattresses, making Bonnel coils the perfect choice for those looking for a budget-friendly option. At the same time, the level of support and comfort cannot be compared with other variants such as offset coils or sheathed coils.
Do you want something that avoids motion transmission? => Endless reel
One lingering problem that many couples face is the disruption caused by their partner’s movements across the bed. In inexpensive mattresses, these movements tend to create waves that affect the entire mattress.
A simple yet effective measure to combat the transmission of motion is the continuous coil.
Basically, rows of continuous steel springs are attached using spirals to create a seamless structure that distributes pressure evenly without causing ripples through the mattress. Not only does this prevent the transmission of movement, but it also does not increase the price range of the mattress to an expensive level.
Looking for the best contouring and support? => Covered coil
Memory foam usually convinces over spring mattresses when it comes to contouring and support. If you want your innerspring mattress to have the best possible properties, you should opt for the covered coil.
The jacketed coil, or pocket coil as it is sometimes called, is the highest quality coil type you can find in a spring mattress. As you might have guessed from the name, this type is made up of individual feathers wrapped in fabric.
A mattress can consist of hundreds to even thousands of such “pockets”, giving it an unprecedented level of support. Also, because these jacketed coils are not connected to each other, they offer near-perfect motion isolation, not to mention much better contouring than other mattresses on the market.
The only factor against buying a spring mattress with pocket coils is cost. These are typically the most expensive mattresses, but for good reason; The durability and convenience of these coils are unparalleled.
Do you need to strike a balance between quality and affordability? => Offset coil
If jacketed coils are too expensive for you but Bonnel coils are too simple, staggered coils could be just the thing for you.
Structurally, the coils are similar to open coils. The difference is that these coils are connected by a network of hinges, which greatly improves load distribution as well as responsiveness to soft pressure.
As a result, offset coils are much better than Bonnel coils or continuous coils for supporting your weight and limiting the transfer of motion. While this also makes it more expensive than these types of coils, the cost is still less than that of a jacketed coil mattress, making staggered coils an attractive alternative.
