A full foam mattress uses foam for both comfort and support, while a hybrid mattress combines a spring unit with foam, latex or other comfort layers. Neither construction is automatically better. The useful comparison is how the materials are arranged and whether that finished design matches the sleeper and bed base.
Quick answer
Choose from the specification, not from the word hybrid or foam. A full foam mattress has no spring core and usually gives a steadier response. A hybrid uses springs beneath comfort layers, so it often feels more responsive. Layer depth, firmness, cover, base compatibility and build quality can matter more than the category name.
What is a full foam mattress?
A full foam or all-foam mattress uses foam through its support structure rather than metal coils.
The simplest design can use one main foam core. A more complex design can combine several foam grades, such as memory foam above a firmer support base.
The All Foam Eco Mattress is a 9-inch medium-firm single-core full foam mattress with a Coolmax cover and double-sided design. The premium All Foam mattress range is also springless, but it uses separate memory foam comfort and support layers.
What is a hybrid mattress?
A hybrid mattress combines a spring support unit with one or more comfort layers above it. Those upper layers may be memory foam, other polyurethane foams, latex or fibres.
There is no single universal hybrid construction. One model may have a substantial pocket-spring unit and deep foam layers, while another may have only a thin foam layer above the springs.
That variation is why competitor comparison pages often reach different conclusions about hybrids. The word describes a mixed construction, not one fixed specification.
The biggest difference is the support system
In a full foam mattress, the deeper foam resists compression and carries the sleeper's load.
In a hybrid, the spring unit carries much of the deeper load while the upper foam or fibre layers provide surface comfort.
That changes the way the mattress responds when you sit, turn or get out of bed.
Foam compresses through its cell structure. Springs compress mechanically and push back towards their original position. The result is often a livelier response from the hybrid, although the exact feel depends on the comfort layers above the springs.
Movement and partner disturbance
Foam tends to localise compression around the area being loaded. This can help reduce movement travelling across the mattress.
Pocket-spring hybrids are also designed so individual springs can respond more independently than a connected spring unit, but there is still a metal support system beneath the comfort layers.
Neither category guarantees zero movement. Mattress size, firmness, sleeper weight and the exact spring or foam design all affect the result.
For couples, the practical question is whether you prefer a settled surface or a more responsive one. Our memory foam mattress for couples guide gives more detail on movement and shared beds.
Response when changing position
A simple support foam core generally recovers quickly when pressure is removed. Memory foam responds more slowly and follows the body more closely.
A hybrid with springs usually has an additional push-back response from the coil unit.
People who change position frequently may prefer a more immediate surface, while others prefer a steadier foam construction with less bounce.
This is preference, not a quality ranking.
Temperature claims need caution
It is common to see hybrids described as cooler because a spring unit contains open space. That may contribute to airflow within the mattress, but the sleeper is in contact with the cover and comfort layers above the springs.
Foam mattresses also vary in cover construction, layer depth and ventilation features.
The room, duvet, mattress protector, clothing and sleeper all influence temperature. Do not assume a hybrid will always sleep cooler or a full foam mattress will always sleep hot.
Our does memory foam make you hot guide explains the other factors that matter.
Edge feel
A hybrid can include reinforced edge springs or firmer perimeter foam, but not every hybrid does.
A full foam mattress can also be built with firmer edges or a uniform core.
If edge support matters because you sit on the side of the bed frequently, check the actual product design rather than assuming springs guarantee a stronger edge.
Weight and handling
Steel spring units add material weight, so many deep hybrids are heavy. Dense full foam mattresses can also be heavy, especially in larger sizes.
The practical issue is whether the mattress can be moved through the property and rotated or turned according to its care instructions.
Check dimensions and handling before delivery if access is narrow.
Turning and rotating
Construction determines care.
The All Foam Eco Mattress is double-sided and intended to be used on either side. Premium layered memory foam models have a defined top comfort layer and should not normally be flipped.
Hybrid mattresses can also be one-sided or double-sided depending on where their comfort materials are placed.
Do not infer turning instructions from the words foam or hybrid. Follow the actual product care information.
Price differences
A hybrid mattress can cost more because it combines a spring unit with comfort materials, but price varies widely across brands and specifications.
A simple full foam construction can offer a lower entry price because it does not require a spring system. That is one reason the Eco Mattress can sit within All Foam's budget mattress pillar.
Price alone still does not tell you whether the construction suits the sleeper. Compare depth, firmness, warranty, cover and materials.

Which is quieter?
A full foam mattress contains no springs, so there is no internal metal coil unit to make spring noise.
A well-made hybrid can also be quiet, particularly when new. Noise can come from the bed frame, base or headboard as well as the mattress.
If a bed creaks, identify the source before blaming the mattress category.
Which provides better support?
Neither system automatically wins.
A suitable foam base can provide excellent structural support. A suitable spring unit can also provide excellent support. Problems occur when the construction is too soft, too shallow, badly matched to the sleeper or placed on an unsuitable base.
Support should be judged from the complete product and the person using it.
Where the All Foam Eco Mattress fits
The Eco Mattress is not a hybrid and not a memory foam mattress.
It uses a 9-inch premium medium-firm foam core, has a Coolmax cover, is double-sided and carries a 3-year warranty. It is currently offered in Single, Double and King sizes.
This makes it a straightforward choice for customers specifically looking for an economically priced full foam mattress rather than a spring-plus-foam hybrid.
If you want a layered memory foam construction instead, compare the premium memory foam mattress range.
Foam versus hybrid checklist
Compare these points before buying:
- support system: foam core or spring unit
- comfort-layer material and depth
- total mattress depth
- firmness description
- movement response
- edge construction
- turning or rotation instructions
- bed-base requirements
- mattress weight and access
- cover and warranty
- exact dimensions
These details are more useful than a headline claim that one mattress type is universally best.

Final answer
A full foam mattress uses foam as its support system, while a hybrid combines springs with comfort layers. Foam usually gives a steadier response and avoids a metal spring core. Hybrids usually feel more responsive because of the spring unit. Neither is automatically more supportive, cooler or longer lasting. Compare the exact construction, depth, firmness, care requirements, bed base and warranty before choosing.
