Ecosa mattress layers do more than just give you something soft to lie on.
They hold your spine in a neutral position, ease pressure, and help you stay cool at night. It’s the kind of design that can mean the difference between tossing and turning or sleeping straight through the night.
Key Takeaways
- Ecosa mattress layers are thoughtfully designed to balance comfort, support, and cooling. These are key factors for a good night’s sleep.
- Each layer plays a role, from pressure-relieving memory foam to breathable latex and sturdy support cores.
- Whether you sleep on your back, side, stomach, or a bit of everything, knowing what’s inside your mattress helps you pick the right feel.
In this blog, we’re diving into what actually makes up a mattress and how each layer works.
We’ll walk you through the structure of Ecosa mattresses, comparing it to other common builds, and break down the extra features that help give your body the support it needs.

Ecosa Mattress Layers
When you unzip an Ecosa mattress, you’ll see that it’s built with three main foam layers beneath a removable cover. Each layer plays a specific role in how the mattress feels and how well it supports you over time.
Let’s go through what’s inside from top to bottom.
Cover
A mattress cover is the outer layer that protects everything inside. It’s the first thing you feel when you get into bed, so it matters more than people think. A good cover should be soft, breathable, and easy to clean.
Most of our mattresses use TENCEL™, a fabric made from sustainably sourced wood pulp. It feels smooth to the touch, stays cool through the night, and naturally resists dust mites and bacteria.
You’ll find TENCEL™ covers on these Ecosa mattresses:
✅ Ecosa Mattress
✅ Aerolux
✅ TrueFirm (firm side)
✅ Essence
✅ Pure
✅ Kids Mattress
✅ Cot Mattress
While TENCEL™ is our go-to for softness and breathability, we also design covers to suit specific sleep needs.
The CoolComfort Mattress, for example, features our Cool+ washable top cover, a double-layered cooling fabric that feels up to 80% cooler than standard mattress surfaces. It’s a solid option if you tend to overheat at night.
All of our covers are removable and washable. So keeping your bed fresh is never a chore.

Comfort Layer
The comfort layer is what you feel the moment you lie down. It determines how soft or firm the mattress feels, how well it cushions your pressure points, and whether it sleeps cool or warm.
Some mattresses stick to a single material. Others layer different foams or springs to create a more balanced feel. Let’s look at the most common types of comfort layers and which Ecosa mattresses use them.
Feature | Memory Foam | Latex | Gel Grid | Hybrid Foam + Springs |
Durability | 6 to 8 years | 8 to 12 years | 8 to 10 years | 7 to 10 years |
Conforming | Very Good | Good | Fair to Good | Good to Very Good |
Pressure Relief | Very Good | Good to Very Good | Good | Good to Very Good |
Motion Isolation | Very Good | Good | Good | Fair to Good |
Temperature Control | Fair to Good | Good to Very Good | Excellent | Good to Very Good |
Sleep Position Suitability | Best for side and combo sleepers | Great for back and stomach sleepers | Best for hot sleepers and combo sleepers | Versatile for all positions |
Memory Foam
Memory foam is soft, slow-moving, and contouring. It’s a staple in many layers of memory foam mattress designs because it adapts to your shape, cradles your joints, and reduces motion transfer between partners.
We use this material across a few of our memory foam mattresses, pairing it with other layers to improve breathability and support.
Used in:
✅ Ecosa Mattress – Gel-infused memory foam for pressure relief and better temperature control
✅ Essence Mattress – Responsive foam over pocket springs for added softness and motion isolation
✅ Aerolux Mattress – Plush pillow-top design with soft memory foam feel
Pros | Cons |
Balanced support and comfort | Slightly more motion transfer than all-foam |
Great for airflow and edge support | Can be heavier and harder to move |
Durable with less sag over time |

Latex
Latex is bouncier than memory foam and naturally cooler. It offers a more “on top” feel rather than letting you sink in. Latex is also eco-friendly and tends to last longer.
You’ll find it in some of our latex mattress options, where it’s used to create a breathable, buoyant sleep surface.
Used in:
✅ Pure Mattress – Natural latex comfort layer with micro coils for airflow
✅ TrueFirm Mattress – Latex comfort layer on the firm side for sturdy support and minimal sink
Pros | Cons |
Naturally breathable and cool | Heavier than foam |
Supportive with a slight bounce | A bit pricier due to natural sourcing |
Hypoallergenic and long-lasting | May feel too firm for some sleepers |

Gel Grid
This isn’t a traditional foam. It’s a flexible polymer grid designed to be breathable and instantly cool to the touch. It’s soft where you need it and firm where you don’t.
You’ll find this material in our cooling mattresses, built to help hot sleepers stay comfortable through the night.
Used in:
✅ CoolComfort Mattress – FlexGel Comfort Grid forms the entire top layer for pressure relief and airflow
Pros | Cons |
Feels cool the second you lie down | May feel unfamiliar to foam users |
Great airflow for hot sleepers | Slightly springy texture some may not prefer |
Responsive and durable |

Hybrid Comfort (Foam + Springs)
Some mattresses combine foam with spring units or micro coils to balance softness and structure. These comfort systems tend to feel more dynamic and breathable.
Our hybrid mattresses use this combo to offer cushioning without compromising support.
Used in:
✅ Essence Mattress – Foam over coils for pressure relief and gentle responsiveness
✅ Pure Mattress – Latex over micro coils for plush feel and airflow
✅ TrueFirm Mattress – Foam and spring combo for a firm, supportive surface
✅ Kids Mattress – Foam layer adjusted for growing bodies, paired with a spring base
Pros | Cons |
Balanced support and comfort | Slightly more motion transfer than all-foam |
Great for airflow and edge support | Can be heavier and harder to move |
Durable with less sag over time |

Support Core Layer
At the base of every mattress is the support core.
This layer does the heavy lifting: keeping your spine aligned, stopping the mattress from sagging, and giving it long-term structure. It’s usually the thickest layer and the firmest.
Support cores are typically made from one of the following materials:
Coil Springs
Coil spring systems are made from connected rows of metal coils. These are most often found in older innerspring mattresses or budget models.
The entire structure moves as one unit, so support tends to feel firmer and bouncier, but motion transfer is higher, and pressure relief is lower.
- Bonnell springs are hourglass-shaped coils joined together by a wire frame. They offer basic support and bounce but don’t contour well to the body. These springs tend to transfer movement across the bed and may lose shape over time.
- Offset springs are similar in shape but have flattened edges that create a hinging effect. This allows them to adjust more closely to your body than Bonnell coils. Offset systems tend to feel a bit more supportive and stable than traditional open coils.

Pocket Springs
If coil systems move as a single unit, mattresses with pocket springs take a more refined approach. Each coil is wrapped in its own fabric sleeve, so they move independently and respond more precisely to your body.
This setup reduces partner disturbance, adds bounce without the wobble, and allows for better airflow through the mattress.
Used in:
✅ Essence Mattress – Traditional pocket spring base for lift and edge support
✅ TrueFirm Mattress – Strong coil system for extra-firm support
✅ Kids Mattress – Gentle pocket springs to support growing bodies
✅ Pure Mattress – 7-zone pocket springs that offer tailored firmness across different areas

High-Density Foam
Foam support cores are firm, stable, and quiet. They don’t contain any springs, so they do a great job at absorbing motion.
These are commonly found in all-foam mattresses and work well if you prefer a mattress that stays still when you move.
Used in:
✅ Ecosa Mattress – High-density polyurethane foam for structure and full-body support
✅ CoolComfort Mattress – Foam base designed to stabilise the FlexGel comfort grid
✅ Cot Mattress – Lightweight foam support core that’s firm enough for safe infant sleep

Pillow Top
A pillow top on a mattress is an extra layer of cushioning sewn onto the surface of a mattress. It adds a plush, cloud-like feel and is often used to soften firmer support systems underneath.
Used in:
✅ Aerolux Mattress – Features a plush pillow top for a soft, welcoming feel the moment you lie down. It also includes a zip-off design, so you can remove the top layer for easier cleaning or switch it out if your comfort needs change.

Edge Support
Edge support refers to how sturdy the sides of your mattress feel when you sit or lie near the edge. Good edge support keeps the mattress from collapsing at the sides and makes it easier to get in and out of bed, especially if you share the space.
This layer usually comes in the form of firmer foam or reinforced coils around the perimeter. It can also be influenced by how the upper layers are styled, such as in a Euro top, where the design naturally reinforces the mattress edge.
Used in:
✅ Essence Mattress – Firmer pocket springs around the edges for a stable feel
✅ Pure Mattress – Zoned edge support that reinforces high-pressure areas
✅ TrueFirm Mattress – Sturdy perimeter to maintain shape over time
✅ Aerolux Mattress – Edge-to-edge stability with no roll-off feel

Foundation
The foundation is the bottom layer that anchors everything. It’s typically made from dense foam or a stabilising base layer designed to add durability and keep the mattress balanced on your bed frame.
In some hybrid models, this layer also absorbs shock from the coils above and keeps them evenly supported.
Used in:
✅ Ecosa Mattress – Solid foam foundation layer for structure and spinal support
✅ Essence Mattress – Firm base layer beneath the coils for added strength
✅ CoolComfort Mattress – High-density foam base below the FlexGel grid
✅ Kids Mattress – Foam and spring combo designed to grow with the sleeper
✅ Pure Mattress – Bottom stabilising layer to support the latex and pocket springs
Even though you’ll never feel the foundation directly, it plays a big part in how long your mattress lasts and how stable it feels over time.

More Designs of Mattress Layers
Yup, we’ve got more to say about layers of mattresses.
Not every bed is built to stay the same forever. Some let you flip, adjust, or reshuffle the insides so you can change how it feels whenever you need to.
Flippable
Flippable mattresses are built with two usable sides, each offering a different feel.
This kind of build can be helpful if your needs change over time, like during injury recovery, pregnancy, or ageing. It also helps prevent uneven wear by encouraging rotation and balance.
Used in:
✅ TrueFirm Mattress – One side is firm, the other is extra-firm. Flipping it lets you choose the level of support that works best for your body. No tools, no fuss—just turn it over.

Adjustable
Some mattresses allow you to rearrange the internal layers to customise the feel. Instead of flipping the entire mattress (or buying a new one at that), you can unzip the cover and move the foam or latex layers around.
Used in:
✅ Ecosa Mattress – Comes with three adjustable foam layers. You can swap the positions to create a medium, medium-firm, or firm feel.
✅ Pure Mattress – Features a flippable latex comfort layer that lets you choose between medium and medium-plush firmness.

Choosing the Right Ecosa Mattress for You
There’s no one-size-fits-all feel when it comes to sleep. The ideal mattress depends on how you sleep, your body type, and what’s inside mattress layers.
Here’s a quick breakdown to help you narrow it down:
Back Sleepers
✅ Ecosa Mattress, Essence Mattress, Pure Mattress
Look for balanced support. A medium-firm feel usually works best, with comfort layers that lightly cushion your hips and shoulders and a stable support core to keep your spine aligned.
Remember, the best mattresses for back sleepers strike that balance without letting you sink too deep.
Side Sleepers
✅ Aerolux Mattress, Ecosa Mattress, CoolComfort Mattress, Pure Mattress
Go for pressure relief. Softer comfort layers like memory foam or gel can contour to your shoulders and hips to reduce pressure build-up and help prevent waking up with aches.
If you tend to sleep on your side most nights, our guide to the best mattresses for side sleepers can help you zero in on the right feel.

Stomach Sleepers
✅ TrueFirm Mattress, Ecosa Mattress, Essence Mattress
You’ll want a firmer feel. This keeps your hips from dipping too low, which can throw off spinal alignment. Look for firm support cores and thinner comfort layers that hold you closer to the surface.
We’ve broken down what to look for in the best mattresses for stomach sleepers to make the search easier.
Combination Sleepers
✅ Ecosa Mattress, Essence Mattress, Pure Mattress
You’ll need a mattress that adapts easily. Responsive layers like latex or gel grid make it easier to shift positions through the night while still giving pressure relief and support where you need it.
Heavier Sleepers
✅ TrueFirm Mattress, Essence Mattress, Ecosa Mattress
Look for dense, durable materials. Firmer transition and support layers can better distribute weight, reduce sagging over time, and keep the mattress feeling stable and supportive.
You’ll also want to prioritise mattresses designed to stay supportive long-term. Check out our tips on the best mattresses for heavy people for a deeper dive.

Sleepers Who Run Hot
✅ CoolComfort Mattress, Aerolux Mattress, Pure Mattress
Go for breathable layers. Mattresses with natural latex, gel-infused foam, or cooling grids help regulate body temperature and improve airflow. Ideal for those who tend to sleep warm throughout the night.
Now that you’ve seen what goes into Ecosa mattress layers, choosing the right one comes down to how you sleep and what feels right for your body. Whether you need contouring comfort, firmer support, or cooling airflow, the right mix of materials can make all the difference.
