Side sleepers normally place their deepest contact through the shoulder and hip, so the mattress must adapt at the surface without losing stability underneath. The All Foam memory foam mattresses range offers three clearly stated constructions rather than a general side sleeper label. Comparing those layers is more useful than assuming one firmness suits everybody.
The best starting point is to identify what feels wrong with the current bed. A surface can feel too resistant at the shoulder, too soft through the middle, difficult to move on or simply uneven because the mattress or bed base is worn. Each problem points towards a different decision.
Start with the side sleeping profile
A side sleeper does not contact the mattress in a flat line. The shoulder and hip project further into the surface, while the waist may need the mattress to rise and support the gap between them.
Shoulder width, hip shape, body weight and sleeping posture influence how deeply each area settles. A broad shouldered person may need more surface adaptation than someone with a straighter profile, even when both people weigh the same.
This is why a mattress described as suitable for side sleepers can still feel very different from one person to another. The complete construction and the sleeper's profile matter more than the label.
Identify the current problem before changing mattresses
Ask which description is closest to the present bed:
- the shoulder feels held above the surface
- the hip feels compressed against a firm layer
- the waist feels unsupported
- the body settles too deeply and movement feels difficult
- one area of the mattress has become lower than the rest
- the bed feels different depending on where you lie
The first three may relate to surface feel and construction. The last three can indicate a worn mattress, unsuitable base or excessive softness. A new mattress choice should address the actual cause rather than simply moving to the opposite firmness.
Memory foam changes the upper contact area
Memory foam responds gradually to heat and pressure. It allows the shoulder and hip to settle into the upper layer while maintaining contact around the surrounding body shape.
This does not mean memory foam supports the mattress by itself. In every All Foam standard mattress, the memory foam sits above a deeper support base. The upper layer changes the immediate sleeping feel, while the base carries most of the mattress load.
For a side sleeper, the important comparison is therefore how much memory foam is used and what supports it.
A deeper comfort layer is not automatically softer overall
The All Foam range uses either 2 inches or 3 inches of memory foam. The two models with 3 inches are still firmer overall because their support constructions are different.
This is an important buying point. Comfort layer depth describes the amount of memory foam available for contouring. The support foam beneath it strongly influences how far the sleeper settles and how stable the mattress feels after that first contact.
Do not judge the mattress from one number. Compare memory foam depth, support grade and total depth together.
Deep Sleeper Comfort for a balanced medium feel
Deep Sleeper Comfort has a 6 inch medium density base beneath a 2 inch memory foam comfort section, with the Air Tech ventilation pad completing the upper build. The covered mattress is approximately 20cm deep.
This is the medium option in the range. It is the clearest starting point for a side sleeper who wants a balanced surface and does not normally enjoy a high firm mattress.
The 2 inch comfort layer provides contouring without creating the deepest memory foam section in the range. The medium density base gives the complete mattress its more accommodating overall feel.
Deep Sleeper Back Care for firmer stability
Deep Sleeper Back Care places a 3 inch memory foam comfort section over 6 inches of high density support foam, with an Air Tech ventilation pad above the layered core.
The extra inch of memory foam gives the shoulder and hip more comfort depth, but the high density base makes the complete mattress high firm. This can suit a side sleeper who likes memory foam contact but wants a stronger sense of stability underneath.
It may feel too resistant for someone who prefers a medium bed, particularly where body weight is lower or the sleeper does not compress the upper layers deeply.
Luxury Deep Sleeper for the deepest construction
Luxury Deep Sleeper uses a 7 inch Luxury Reflex support base with a 3 inch memory foam comfort section and an Air Tech ventilation pad. With its cover, the mattress is approximately 25cm deep.
It is the deepest standard model and has a luxury high firm feel. The additional support depth creates a more substantial construction rather than simply adding more softness.
This option may appeal to a side sleeper who wants the deepest mattress in the range but still prefers firm, resilient support. Check bed height before ordering.
Match the model to the type of side sleeper
A lighter side sleeper who rarely compresses a firm surface may begin by comparing Deep Sleeper Comfort. The medium construction is more likely to allow the shoulder and hip to engage the surface without the stronger resistance of the high firm bases.
A side sleeper of average or higher body weight who prefers stability may compare Deep Sleeper Back Care. The 3 inch memory foam layer provides contouring above a firmer base.
A customer wanting a deep, substantial mattress and a luxury high firm response may compare Luxury Deep Sleeper. The deeper Reflex support layer is the defining difference.
These are practical starting points, not guarantees. Preference matters.
Consider whether you stay on your side
Some people remain on one side for most of the night. Others move between side and back sleeping or rotate partly towards the front.
A person who changes position frequently may pay more attention to how easy the mattress feels to move across. Memory foam has a slower response than Reflex or standard polyurethane foam, although the support base also changes the overall behaviour.
Think about the whole night rather than only the position used when falling asleep.
Shared beds require a compromise
One mattress provides one construction across the full width. If one person is a side sleeper who wants more contouring and the other prefers a firmer, flatter feel, both should compare the models together.
A medium option can be a sensible first comparison where preferences differ, but it is not automatically the final answer. Body weight can make the same surface feel firmer to one person and softer to another.
Discuss which current problem matters most. A mattress chosen only for one sleeper can create a new problem for the other.

Check the pillow at the same time
The pillow fills the space between the head and mattress. A side sleeper with broad shoulders may need a different pillow height from someone with a narrower frame.
A mattress that lets the shoulder settle further can change the pillow height that feels comfortable. Review both together.
Use a pillow that suits the sleeper and follow any care or replacement guidance supplied with it.
Inspect the bed base before ordering
A foam mattress needs a level and supportive base. Loose slats, a bowed platform, a damaged centre rail or wide unsupported gaps can create an uneven sleeping surface.
Remove the old mattress and inspect the frame. Correct any structural problem before placing a new mattress on it.
A side sleeper can notice a local dip strongly because the shoulder and hip concentrate load in smaller areas. Replacing the mattress without repairing the base may reproduce the same uneven feel.
Measure the frame and finished height
All Foam standard mattresses are available in Single, Double, King Size and Super King. Use the exact dimensions shown on the product cards and measure the internal bed space.
Older frames may differ from current UK sizes. A mattress that is too tight can bow or become difficult to rotate and remove.
Also check the finished height. Luxury Deep Sleeper is deeper than the other standard models. Consider fitted sheets, headboard position, bedside furniture and ease of getting into bed.
Know when a topper is not enough
A topper can change the surface of a structurally sound mattress, but it cannot rebuild failed support. If the current mattress has deep sagging, broken edges or clearly uneven areas, replacement is usually the more appropriate route.
Side sleepers sometimes search for extra cushioning when the real issue is a dip beneath the hip or shoulder. Adding another layer follows the same shape.
Inspect the complete bed before choosing between a topper and a mattress.
Avoid choosing from medical claims
A mattress changes feel, surface contact and support. It should not be treated as a medical treatment or a guaranteed solution for pain.
Persistent, severe or unexplained symptoms need suitable professional advice. Mattress selection should be based on verified construction, preferred firmness, bed condition and accurate sizing.
Avoid broad promises that one product is medically best for every side sleeper.
A side sleeper comparison checklist
Before ordering, confirm:
- which part of the current bed feels wrong
- whether the mattress and base are structurally sound
- how deeply the shoulder and hip currently settle
- whether a medium or high firm surface is preferred
- whether 2 inches or 3 inches of memory foam sounds more suitable
- how often the sleeper changes position
- whether both partners agree on the feel
- the exact internal bed dimensions
- the acceptable finished bed height
- whether the pillow may also need reviewing
Final guidance
A memory foam mattress for side sleeping should provide enough upper layer response for the shoulder and hip while retaining dependable support beneath the waist and torso.
Deep Sleeper Comfort is the medium starting point. Deep Sleeper Back Care adds a deeper memory foam layer above a high density base. Luxury Deep Sleeper uses the deepest support construction and a luxury high firm feel.
Choose from the complete layer build, not from the phrase side sleeper alone. The right mattress is the one that matches the person's profile, preferred resistance, bed base and exact frame size.
