When layering different components like base springs, latex topper, and microcoil topper in a mattress, the order can affect the overall feel and performance of the bed.
When we look at each component’s function, it may help you understand what the affect might be as you construct your mattress.
Your bases springs provide foundational support. They typically go at the bottom as they form the core support structure of the mattress.
The microcoil topper will add a layer of additional support and responsiveness due to its smaller coils. It can go either above or below the latex topper, depending on the desired feel, for example.
If you are placing microcoils on top of latex, they can provide a slightly more responsive feel, as the coils respond quickly to pressure and movement.
When you place the microcoils beneath the latex it may provide a slightly softer feel with a bit more contouring, as the latex will conform to the body while still benefiting from the support of the microcoils.
The latex is known for its buoyancy, comfort, and pressure relief. It generally works well as a top layer because it contours to the body, provides comfort, and enhances the overall feel of the mattress.
A quick pause, are you asking if the micro coil layer is not a topper and simply a microcoil independent layer? Most microcoil toppers have added, wool, latex or cotton in addition to the microcoils. So we dont want to conflate the two.
An independent micro coil layer is often used to replace a foam (usually memory foam) counterpart, to increase air flow, reduce heat retention, and provide more targeted support to different parts of the body, such as hips and shoulders. They can also improve spinal alignment, for a more comfortable nights sleep. Micro coils can also improve the durability of a mattress.
Placing microcoils above or below the latex can indeed produce different feels. Above the latex, you may feel more responsiveness and bounce. Below the latex, you might experience a softer, more contouring sensation.
If the microcoil layer were coils only (without additional foam), it would typically go beneath the latex. This is because coils alone would lack the conforming comfort that latex provides and might feel too firm or uneven directly under the body.
Given your setup of base springs, a latex topper, and a microcoil topper with foam:
The most common and likely optimal configuration would be base springs at the bottom, followed by the microcoil topper with foam, and then the latex topper on top. This setup balances support, responsiveness, and comfort.
As you well know, mattress comfort is highly subjective. If you have the ability to adjust or test the layers before finalizing, you could experience the differences for yourself.
I would say, there isn’t necessarily one “correct” order, the setup of base springs at the bottom, followed by the microcoil topper with foam, and then the latex topper on top is a commonly effective configuration.
Hopefully, this clears things up and doesnt confuse things even more.
