Comfort Layers of Mattress

Layered mattresses provide pressure alleviation and support. Most mattresses include comfort, transitional, and support layers. Each component impacts a mattress’s comfort. Top comfort layers are 1 to 4 inches thick. Some designs feature just one comfort layer, while others have numerous. Comfort systems are multilayer designs. Comfort layers are meant to cushion the body and ease stress. Material quality affects noise, temperature regulation, and motion isolation. We compare comfort layer materials and layouts to help you select the finest mattress with no fiberglass.

Mattress Construction:

Mattresses are often layered. Most use layers for effects. Top comfort layers and a support core make up a mattress. A transitional layer is typically employed between the softer comfort system and the denser support core.


The uppermost mattress layers are comfort layers. Firm models feature 1- to 2-inch comfort systems. Plusher mattresses employ thicker materials or extra layers to generate a 4-inch height. These layers are meant to optimize comfort, thus their name. Memory foam, polyfoam, and latex relieve pressure points. These layers cushion a sleeper from the strong support core, which would be unpleasant. Comfort layers contour the body to relieve stress, but they must also be sensitive to prevent sinking.

Transitional Layers

Transitional layers combine comfort and support features. They provide mild to moderate contouring and a barrier between you and the core. Transitional layers decrease sagging using latex and polyfoam. Some have a zoned arrangement to encourage healthy spinal alignment in particular places. 1 to 3 inches thick is transitional layers.

Support Core

A support core stabilizes the mattress and helps the higher layers perform. This bed section employs steel coils and high-density polyfoam for durability. Most mattress support cores are between 6 and 10 inches thick. Sometimes the perimeter is strengthened to make getting in and out of bed simpler.

Flippable Mattresses?

Flippable mattresses aren’t standard. A single support core links two independent comfort systems so that you may sleep on either side of the mattress. Some types have two firmness settings for flexibility. Sleeping on alternate sides may help improve your mattress’ lifetime by preventing deep surface imprints from developing.

Why Are Mattress Comfort Layers Important?

Comfort systems differ by brand and model, but they all aim to improve sleep. Material quality affects contouring, pressure alleviation, and motion isolation. These and other factors affect sleep comfort.

For Pressure Relief

Poor spinal alignment may cause uncomfortable pressure accumulation and disrupt sleep. Softer comfort layers contour the body and alleviate hip, shoulder, and spine discomfort. Firmer comfort layers reduce strain by appropriately distributing body weight.


Polyfoam encompasses polyurethane foams. The petrochemical-derived synthetic substance comes in variable densities so mattresses may use it in several ways. Comfort systems used polyfoam until recently. More mattresses include memory foam, latex, and other elements. Polyfoam is a common comfort layer. Uniform or complex polyfoam comfort layers are typical. Smooth uniform variations are good for quilting and upholstery layering.

Memory Foam

The heat-sensitive foam molds to your body while you sleep. Memory foam has great elasticity, so it slowly returns to form when pressure is released. Memory foam layers “remember” your body’s imprint. Memory foam’s better cradling and durability make it popular in luxury mattresses. Some sleepers prefer comfort layers with less sinkage over the body embrace. Memory foam traps heat, although newer models include cooling elements like gel infusions or open-cell designs.
