A layered foam mattress separates surface comfort from deeper support. This makes memory foam mattresses easier to compare because you can see which material is used in each part of the construction instead of relying on a vague comfort name.
Every standard All Foam mattress uses three main parts. There is an Air Tech ventilation pad, a memory foam comfort layer and a supportive foam base. The depth and type of the lower support foam change between models, which creates a clear choice between medium, firm and deeper high firm constructions.
This guide explains why layered construction is useful, what each part contributes and how to compare the three mattresses in the current All Foam range.
What is a layered foam mattress?
A layered foam mattress uses two or more foam sections with different roles. The upper section is normally selected for the surface feel. The lower section provides most of the depth and structural support.
This is different from describing a mattress only by its total depth. Two mattresses can have a similar overall depth but feel different because their comfort layers and support bases are not the same.
A useful mattress description should therefore answer four questions.
1. What material is used at the sleeping surface?
2. How deep is that comfort material?
3. What foam supports it underneath?
4. What is the complete mattress depth?
When these details are available, you can compare the construction rather than trying to interpret names such as luxury, comfort or back care without further information.
Why separate layers are useful
A single foam grade cannot always provide every characteristic a customer wants. A softer material may feel comfortable at the surface but may not provide the stable base required for a complete mattress. A firmer foam may provide useful support but can feel too direct when used as the only sleeping surface.
Layering allows the surface and the base to be chosen for different purposes. In the All Foam range, memory foam forms the upper comfort section. Medium density foam, high density foam or Luxury Reflex foam forms the main support section, depending on the model.
This makes the construction easier to explain. The customer can see where the slower responding memory foam sits and what type of foam supports it.
The Memory Foam Mattress Buying Guide explains how to compare memory foam depth, support foam, mattress size, bed base and total depth before ordering.
The three parts used in every All Foam mattress
Although the standard mattresses have different depths and firmness levels, they share the same general structure.
Air Tech ventilation pad
The Air Tech ventilation pad is listed as part of every standard mattress construction. It sits with the foam layers and forms one of the three named parts of the mattress.
The presence of a ventilation pad should be considered alongside the rest of the product rather than treated as the only reason to choose a mattress. Room temperature, bedding, protectors and personal preference can all affect how warm a sleeping surface feels.
Memory foam comfort layer
Memory foam forms the upper comfort layer. It responds more slowly than the support foams used underneath and follows the shape applied to it more closely.
The standard range uses either 2 inches or 3 inches of memory foam. This difference changes how much memory foam sits between the sleeper and the support base.
More memory foam does not automatically mean that a mattress is suitable for everyone. Some customers prefer a deeper contouring section. Others prefer a more direct connection with the support foam below. The right choice depends on the complete construction and the feel you prefer.
Support foam base
The support base forms most of the mattress depth. It helps create the general firmness and stability of the finished product.
Deep Sleeper Comfort uses medium density foam. Deep Sleeper Back Care uses high density foam. Luxury Deep Sleeper uses Luxury Reflex foam.
These materials are not interchangeable labels. The support base is one of the main reasons the three mattresses feel different even where the memory foam depth is the same.
Why total depth cannot explain the whole mattress
Total depth is useful because it tells you how high the mattress will sit on the bed and how substantial the overall construction is. It does not explain the feel on its own.
Deep Sleeper Comfort has a total depth of 20cm. It uses 2 inches of memory foam above 6 inches of medium density support foam.
Deep Sleeper Back Care has a total depth of 22.5cm. It uses 3 inches of memory foam above 6 inches of high density support foam.
Luxury Deep Sleeper has a total depth of 25cm including the cover. It uses 3 inches of memory foam above 7 inches of Luxury Reflex support foam.
The last two mattresses both use 3 inches of memory foam, yet their support layers and total depths are different. This is why the layer specification matters more than a depth figure viewed by itself.
Deep Sleeper Comfort for a medium feel
Deep Sleeper Comfort is the medium option in the standard range. It is also the most economical of the three mattresses.
Its construction includes an Air Tech ventilation pad, 2 inches of quality memory foam and 6 inches of medium density support foam. The total depth is 20cm.
This model suits customers who want a balanced medium feel rather than the firmer base used in the other two mattresses. The shallower memory foam layer also means there is less slow responding material above the support base.
Choose this model when you prefer a medium mattress and want the simplest standard construction in the range. Do not choose it only because it has the lowest price. The firmness and layer depths should still match your preference.
Deep Sleeper Back Care for firmer support
Deep Sleeper Back Care is the high firmness option.
It includes an Air Tech ventilation pad, 3 inches of quality memory foam and 6 inches of high density support foam. Its total depth is 22.5cm.
Compared with Deep Sleeper Comfort, it adds one more inch of memory foam and changes the lower layer from medium density foam to high density foam. The result is a deeper construction with a firmer and more stable base.
The product name should not be interpreted as a medical promise. Choose it because you prefer its stated high firmness and high density support layer, not because a mattress name alone can diagnose or treat discomfort.
The Soft, Medium or Firm Mattress Guide explains how sleeping position, body weight, a shared bed and the condition of the current mattress can affect a firmness decision.
Luxury Deep Sleeper for the deepest construction
Luxury Deep Sleeper is the deepest mattress in the standard All Foam range.
It uses an Air Tech ventilation pad, 3 inches of quality memory foam and 7 inches of Luxury Reflex support foam. The complete depth is 25cm including the cover.
This mattress shares the same memory foam depth as Deep Sleeper Back Care, but the support layer is one inch deeper and uses Luxury Reflex foam instead of high density foam.
The product page describes this as a luxury high firm mattress. Choose it when you want the most substantial standard construction, a deeper support base and the quicker recovery character of Reflex foam beneath the memory foam.
A deeper mattress also changes the height of the sleeping surface. Check that fitted sheets can accommodate the depth and that the finished height suits the bed frame and headboard.
Comfort layer depth changes the surface experience
The comfort layer is the first foam section beneath the cover. Its depth influences how much the sleeper engages with memory foam before reaching the support layer below.
A 2 inch memory foam layer gives a shallower comfort section. A 3 inch layer creates a deeper section of the same type of material.
This does not mean that one depth is always better. A customer who prefers a balanced medium mattress may favour Deep Sleeper Comfort. A customer who wants a deeper memory foam section with a firmer base may favour Deep Sleeper Back Care. A customer who wants the deepest standard build may prefer Luxury Deep Sleeper.
The important point is to compare comfort depth and support material together. Looking at only one layer can lead to the wrong conclusion about the finished mattress.
The support layer creates the foundation
The lower foam section carries most of the mattress depth. It provides the foundation beneath the memory foam and has a major influence on the firmness description.
Medium density foam is used in Deep Sleeper Comfort. This supports the balanced medium position of that mattress within the range.
High density foam is used in Deep Sleeper Back Care. This provides the firmer base associated with the high firmness rating.
Luxury Reflex foam is used in Luxury Deep Sleeper. Reflex foam recovers more quickly than memory foam, so it gives the deeper mattress a responsive support section beneath the slower upper layer.
Density and firmness should not be treated as the same measurement. A foam can be described by its density, its firmness and its intended application. The Foam Density and Firmness Guide explains why these terms should be read separately.
Layered construction makes product comparison clearer
Online mattress descriptions often use broad phrases such as premium comfort, advanced support or luxury sleep. These expressions do not tell you what is inside the product.
A layer specification is more useful because it provides details that can be compared directly.
You can compare the depth of memory foam.
You can compare the material used in the base.
You can compare total mattress depth.
You can compare the stated firmness.
You can then decide whether the differences matter to you.
This approach reduces the need to guess from the product name. It also makes it easier to explain why two mattresses with memory foam at the surface can still feel different.
A layered foam mattress is not the same as every foam mattress
The phrase foam mattress covers many possible constructions. Some mattresses use one main foam grade. Others combine several materials. Some use memory foam only near the surface. Others use different comfort and support foams throughout.
The All Foam standard range uses full foam constructions rather than a spring unit. Each model combines memory foam with a separate support foam base.
Customers comparing these products with sprung alternatives should focus on the internal support system, not only the surface material. The Foam Mattress and Spring Mattress Comparison explains the differences in construction, surface response, support and product selection.
Neither construction type is automatically correct for every customer. The better choice is the one whose materials, depth and firmness match the required feel and the condition of the bed base.
When a mattress topper may be enough
A full mattress is not always required when the existing mattress remains level, stable and supportive.
A topper adds a separate foam layer above the mattress. It can adjust the surface feel without replacing the support structure underneath.
The mattress topper range includes memory foam, medium density foam, high density foam and Reflex foam options. These products provide different surface responses and firmness choices.
A topper cannot repair a damaged support core, broken springs or a significant dip. If the mattress underneath is no longer structurally sound, another comfort layer will follow the same uneven surface.
Read the Mattress Topper or New Mattress Guide before ordering when you are uncertain whether the problem is at the surface or within the mattress structure.
This distinction matters because layered construction only works properly when every section has a sound base beneath it.
Custom layers provide more control
The three standard mattresses cover medium, high firmness and luxury high firm choices. Some customers may require a different layer arrangement.
The custom foam mattress builder allows a customer to choose a standard UK size, a total depth of 8, 9 or 10 inches, one to three layers and a selection of foam grades.
The available grades include Medium, High, Severe Very Firm, Reflex Medium, Reflex Grey and Memory Foam.
A custom build is useful when the standard range does not provide the preferred layer count, depth split or support material. It should still be approached as a complete construction. Adding more layers does not automatically improve a mattress. Each layer needs a clear role and the finished arrangement needs to match the required feel.
The builder validates the chosen layer depths and calculates the price from the selected materials. Contact All Foam when the required width or length falls outside the standard online sizes.
The bed base remains part of the result
A layered mattress can only rest as evenly as the surface beneath it.
Inspect the bed base before replacing the mattress. Look for broken slats, bowed sections, loose fittings and unsupported gaps. A damaged base can affect how a new mattress feels and may cause it to follow an uneven shape.
A stable and level base helps the support foam perform as intended. A flexible or damaged base can change the response of the complete mattress.
Check the guidance supplied by the bed manufacturer when using slats or a specialist frame. Do not assume that every base is suitable simply because the mattress fits within the outer dimensions.
This check is especially important when changing from a spring mattress to a full foam construction because the new mattress may respond differently to the same base.
Measure the bed and the finished height
The standard All Foam range is available in Single, Double, King Size and Super King.
Single measures 90cm by 190cm.
Double measures 135cm by 190cm.
King Size measures 150cm by 198cm.
Super King measures 180cm by 198cm.
Measure the usable bed area rather than relying only on the name of the current mattress. Older frames and imported beds may not match standard UK dimensions.
Also check the finished height. A 25cm mattress sits higher than a 20cm mattress. This can affect the visible height of a headboard, the ease of getting into bed and the depth required for fitted sheets and protectors.
Measure width, length and available depth before ordering. This is more reliable than assuming that a deeper mattress will fit every existing bed setup.
The cover completes the construction
Each standard mattress includes a premium navy border with a diamond quilted zip off cover. The product details also list Heat Dispersion Technology.
The cover creates the finished sleeping surface and protects the foam construction. Follow the supplied care instructions before cleaning it. A zip off design should not automatically be treated as machine washable.
A suitable mattress protector can help keep the surface clean, but it should fit the complete mattress depth without pulling tightly at the corners.
Do not soak the foam core. Keep the mattress dry, ventilated and properly supported. The Foam Product Care Guide provides practical guidance for mattresses, toppers and foam products.
Warranty information should be part of the comparison
Every standard All Foam mattress includes a 6 year warranty, subject to the warranty terms.
The warranty should be reviewed before purchase. It explains the applicable cover and the customer responsibilities.
A warranty does not replace correct measuring, suitable product selection or a sound bed base. Damage caused by moisture, unsuitable support or incorrect care may be treated differently from a manufacturing issue.
Keep the order information and follow the instructions supplied with the mattress. This gives a clearer record if a genuine product problem needs to be assessed later.
Common mistakes when comparing layered mattresses
The first mistake is choosing by total depth alone. A deeper mattress may use a different support material, so depth does not provide the full answer.
The second mistake is looking only at the memory foam. The lower support layer forms most of the mattress and has a major influence on stability and firmness.
The third mistake is assuming that more layers always create a better mattress. A clear two foam construction can be more suitable than a complicated build when the materials and depths match the customer.
The fourth mistake is using a product name as a medical claim. Terms such as back care should not replace a comparison of firmness, materials and construction.
The fifth mistake is ignoring the bed base. Even a carefully selected mattress can feel uneven when it rests on a damaged frame.
The sixth mistake is buying a full mattress when a topper would provide the required surface adjustment, or buying a topper when the mattress underneath needs replacing.
A simple way to compare the standard range
Start with the general feel.
Choose Deep Sleeper Comfort for medium firmness. Choose Deep Sleeper Back Care for high firmness. Choose Luxury Deep Sleeper for a luxury high firm feel.
Then compare the memory foam depth.
Deep Sleeper Comfort uses 2 inches. The other two mattresses use 3 inches.
Next compare the support material.
Deep Sleeper Comfort uses medium density foam. Deep Sleeper Back Care uses high density foam. Luxury Deep Sleeper uses Luxury Reflex foam.
Finally compare the total depth.
The three mattresses measure 20cm, 22.5cm and 25cm.
This four stage comparison keeps the decision focused on the parts that actually differ.
Questions to answer before ordering
What firmness do you prefer based on the mattress you use now?
Do you want 2 inches or 3 inches of memory foam?
Which support material best matches your preference?
Does the exact mattress size fit the usable bed area?
Will the finished depth suit the frame, headboard and fitted sheets?
Is the bed base level and supportive?
Does the current mattress need replacing, or would a topper be enough?
Have you reviewed the care information and warranty terms?
Answering these questions gives you a more reliable basis for choosing than a product name or a single depth figure.
Final guidance on layered foam mattresses
Layered foam mattresses remain easy to understand because the comfort and support sections can be described separately.
Deep Sleeper Comfort combines 2 inches of memory foam with 6 inches of medium density support foam for a medium feel.
Deep Sleeper Back Care combines 3 inches of memory foam with 6 inches of high density support foam for a firmer feel.
Luxury Deep Sleeper combines 3 inches of memory foam with 7 inches of Luxury Reflex support foam for the deepest standard construction.
Compare the complete layer build, not just the memory foam or total depth. Check the bed size, base, cover, care information and warranty before ordering. A clear understanding of every layer makes it easier to choose a mattress that matches the feel and construction you actually want.
