Non-Sprung Mattresses at a Glance
No Traditional Springs
Support comes from foam, memory foam or other layered materials rather than a conventional spring unit.
Consistent Support
The mattress construction can provide an even sleeping surface without the movement associated with traditional spring systems.
Low Movement Transfer
Foam-based constructions can absorb movement, making them an option worth considering for couples.
Different Foam Options
Non-sprung mattresses can use different foam densities, layers and constructions to create different feels.
What Is a Non-Sprung Mattress?
A non-sprung mattress is made without traditional springs. Instead, its support and comfort come from materials such as foam, memory foam and other layered constructions. The exact feel depends on the materials used, their density and how the mattress is constructed.
Types of Non-Sprung Mattress
Foam Mattress
Uses foam as the main support and comfort material. Foam construction can provide a stable feel with less spring movement.
Memory Foam
Uses a viscoelastic foam layer designed to respond to body heat and pressure, creating a more contouring feel.
Layered Foam
Combines different foam layers to balance support, cushioning, firmness and responsiveness.
Non-Sprung vs Pocket Sprung Mattresses
| Feature | Non-Sprung | Pocket Sprung |
|---|---|---|
| Support system | Foam or layered materials. | Individual pocket springs with comfort layers. |
| Feel | Can range from stable to highly contouring depending on construction. | Generally more responsive, depending on spring and comfort-layer design. |
| Movement | Foam can absorb movement effectively. | Individual springs can help limit movement transfer. |
| Pressure relief | Depends heavily on the foam and comfort layers. | Comes from the combination of spring response and comfort layers. |
| Best for | Sleepers who prefer a stable or contouring surface. | Sleepers who want responsive individual spring support. |
Choosing the Right Firmness
Non-sprung mattresses can be made in different firmness levels, so do not assume that every foam mattress will feel soft. The materials, density and construction determine how supportive and yielding the finished mattress feels.
Soft
A softer construction provides more cushioning and allows the body to sink further into the comfort layers.
Medium
A balanced option for sleepers who want a combination of cushioning and support.
Firm
Provides a more stable sleeping surface with less sinkage, although the exact feel depends on the mattress construction.
Who Are Non-Sprung Mattresses Suitable For?
Couples
Foam constructions can reduce the amount of movement transferred across the mattress, which may be useful when sharing a bed.
Side Sleepers
A suitable foam construction can provide cushioning around pressure points. Focus on the overall firmness and comfort layers rather than simply choosing foam.
Back Sleepers
A supportive foam mattress can provide a stable surface, but the right firmness depends on body shape, weight and personal preference.
Front Sleepers
A firmer non-sprung mattress may suit sleepers who prefer less sinkage, but individual comfort and support remain important.
Non-Sprung vs Memory Foam
Memory foam is one type of non-sprung mattress construction.
The term "non-sprung" describes what the mattress does not contain: traditional springs. Memory foam describes a particular material. Therefore, a memory foam mattress can be non-sprung, but not every non-sprung mattress is made from memory foam.
Do Non-Sprung Mattresses Sleep Hot?
This depends on the materials and construction. Some foam mattresses can retain more body heat than traditional spring mattresses, while modern designs may use breathable foams, covers or ventilation features to improve airflow.
Check the Materials
Look at the type and density of foam used rather than assuming all foam mattresses have the same temperature characteristics.
Look for Breathability
Ventilated foams and breathable covers can help with airflow and temperature management.
Consider Your Preference
If you tend to sleep warm, prioritise mattresses specifically designed with cooling or breathable materials.
Does Mattress Depth Matter?
Yes. Non-sprung mattresses are available in different depths, and the depth can affect the feel, finished bed height and how the mattress works with your existing base.
Check the Complete Bed Setup
Before buying, check the mattress dimensions against your bed base. A deeper mattress will increase the finished sleeping height and can affect access to drawers, headboards and other parts of the bed. Our Mattress Depth Buying Guide explains what to consider.
Choose the Right Bed Base
A non-sprung mattress still needs an appropriate foundation. Check the mattress manufacturer's requirements for the type of base, support and slat spacing before using it on an existing bed.

What is a non-sprung mattress?
A non-sprung mattress does not contain a traditional spring unit. Support comes from materials such as foam, memory foam or other layered constructions.
Are non-sprung mattresses firm?
They can be. Non-sprung mattresses are available in different firmness levels, from softer options through to firm constructions. The materials and design determine the final feel.
Are non-sprung mattresses good for couples?
They can be a good option if reducing movement transfer is important. Foam-based mattresses can absorb movement rather than transmitting it through a spring system.
Are non-sprung mattresses good for back support?
They can provide consistent support, but the right mattress depends on its construction, firmness and your individual requirements. No single mattress type is best for every sleeper.
Are memory foam mattresses non-sprung?
Yes, a memory foam mattress can be non-sprung because memory foam does not use traditional springs. However, non-sprung mattresses are not limited to memory foam.
Do non-sprung mattresses sleep hot?
Some foam mattresses can retain heat, but this varies by material and construction. If you sleep warm, look for a mattress with breathable or cooling features.
Can you use a non-sprung mattress on a divan?
Often, yes, but compatibility depends on the mattress and the specific divan. Check the manufacturer's requirements for the base type and support before buying.
Can you use a non-sprung mattress on a slatted bed?
It depends on the mattress. Check the manufacturer's requirements for slat spacing and support before placing a non-sprung mattress on a slatted frame.
