About 65% of UK adults sleep on their side, according to a 2025 study published in the Huffington Post, making it the most common sleep position. But side sleeping puts unique demands on your mattress - your shoulder and hip absorb most of your body weight, and without proper pressure relief, you can wake up with numbness, tingling, or joint pain.

1. Simba Hybrid Mattress - Best Overall for Side Sleepers
The Simba Hybrid is the mattress we recommend most often to side sleepers, and it's our top pick. What makes it work so well for this position is the five-layer construction: a base of 2,000+ Aerocoil micro-springs, layers of temperature-regulating Simba-Pure foam, and a top layer of British wool and silk. The springs respond independently to your body, so your shoulder and hip sink in just enough while your midsection stays supported.
For side sleepers, the key detail is the zoned spring system. The springs are engineered with varying tension - softer under the shoulder zone where you need cushioning, firmer under the hips and lumbar area where you need support. Independent pressure-mapping tests rate the pressure distribution highly, and the Simba consistently shows lower peak pressures at the shoulder compared to pure memory foam mattresses of similar price.
The natural wool layer is a genuine benefit for side sleepers who tend to run hot. Wool wicks moisture and regulates temperature better than synthetic alternatives, which matters when you're pressing more body surface area into the mattress. The 200-night trial and 10-year guarantee take the risk out of buying a mattress without trying it first.
Best for: Side sleepers who want premium hybrid construction and don't mind spending for proven pressure relief technology. Also excellent for combination sleepers who switch between side and back during the night.

If you're a side sleeper who also deals with lower back pain, the Emma Premium is my top recommendation. Emma's body-adaptive foam uses three distinct layers: the top Airgocell layer is temperature-regulating and breathable, the middle contouring layer adapts to your body shape, and the base provides firm support. What sets it apart for side sleepers is the zoned construction - it's engineered to be firmer under the lumbar region while providing extra give around the shoulders and hips.
In practice, we often see side sleepers with lower back pain caused by the pelvis tilting when the hip sinks too far into a soft mattress. The Emma Premium addresses this directly by zoning the support - your shoulder gets the cushioning it needs while your lower back stays properly aligned. A 2024 study in the Journal of Chiropractic Medicine found that medium-firm zoned mattresses significantly reduced morning pain in people with chronic lower back pain, and the Emma Premium follows exactly this principle.
The Airgocell top layer is another standout for side sleepers. Because you're pressing more of your body into the mattress, heat buildup is a real issue โ waking up sweaty on the side you sleep on is one of the most common complaints in owner reviews. The open-cell structure of Airgocell allows better airflow than standard memory foam, which keeps the sleeping surface cooler throughout the night.
Best for: Side sleepers with existing lower back pain, or those who want targeted zoning that adapts to different body pressures. The 200-night trial and 10-year warranty make it a safe choice.
View on Amazon โ3. Silentnight 1200 Pocket Mattress - Best Budget for Side Sleepers
The Silentnight 1200 Pocket proves you don't need to spend a grand to get a mattress that works for side sleeping. With 1200 individual pocket springs, each spring moves independently, so the ones under your shoulder compress more than the ones under your hips. This provides natural pressure relief through the spring action alone, without relying on thick layers of memory foam that can sleep hot.
At around ยฃ315 for a single and ยฃ468 for a double, it's the most affordable option on this list. The key is the pocket spring count - 1200 springs in a double means a higher spring density than standard budget mattresses, which translates to better contouring. Silentnight uses a layer of soft comfort foam on top of the springs, which adds a small amount of cushioning for the shoulders without compromising the spring support.
There is a trade-off compared to the premium options. The comfort layer is thinner (about 4cm versus 8-12cm on hybrids), so heavier side sleepers over 14 stone may find it lacks enough pressure relief at the shoulder. It's also a slightly firmer feel overall - I'd rate it a 7/10 on the firmness scale, which some side sleepers may find too firm if they prefer a soft, sinking-in sensation.
Best for: Side sleepers on a budget who prefer a traditional spring feel over memory foam. Ideal for lighter individuals under 13 stone. The 40-night trial is shorter than other options but still gives you time to adjust.
View on Amazon โ4. Tempur Sensation Mattress - Best Premium for Side Sleepers
The Tempur Sensation is the most expensive mattress on this list by a significant margin, but for side sleepers with chronic shoulder or hip pain, it can genuinely change how you sleep. Tempur's proprietary TEMPUR material - originally developed by NASA - has a unique viscoelastic property that responds to body heat and weight. It moulds precisely to your body's shape, distributing weight so evenly that pressure points essentially disappear.
I've referred several patients with severe shoulder impingement to this mattress, and the feedback has been consistently positive. One patient who had been sleeping with a pillow between her arm and body for years to cushion her shoulder reported being able to sleep without it after three weeks on the Tempur Sensation. The material absorbs movement completely too, which matters for side sleepers who tend to shift position more during the night.
The Sensation model is rated as medium firmness - softer than the brand's Original or Classic models, which makes it more suitable for side sleeping. It provides that slow-sinking pressure relief that memory foam is known for, but at a level of precision that cheaper foams can't match. The trade-off is breathability: Tempur material retains more heat than hybrid constructions, so if you sleep very hot, a hybrid may still be a better choice.
Best for: Side sleepers with diagnosed shoulder, hip, or joint pain who want the most advanced pressure-relieving material available. The 100-night trial and 10-year warranty reflect the build quality.

The Otty Hybrid hits the sweet spot for side sleepers who also occasionally sleep on their back or stomach. With 1,600 pocket springs combined with HD memory foam and a breathable outer layer, it provides a balanced medium-firm feel that works across multiple positions. For side sleeping specifically, the memory foam layer adds enough contouring to relieve shoulder pressure while the springs prevent the hip from sinking too deep.
What makes the Otty stand out at its price point is the spring count. At around ยฃ599 for a king, you're getting 1,600 pocket springs - more than many mattresses costing twice as much. Higher spring density means more precise contouring, which directly benefits side sleepers who need different levels of support across different body zones. The breathable outer cover uses a blend of polyester and natural cotton that helps with temperature regulation.
I recommend the Otty to side sleepers who aren't sure whether they want a pure memory foam or pure spring mattress. The hybrid construction gives you the benefits of both: enough contouring for shoulder comfort and enough support to keep your spine aligned when you roll onto your back during the night. The 200-night trial is generous, and the 10-year warranty provides peace of mind.
Best for: Combination sleepers who mainly sleep on their side but also shift to back or stomach. Side sleepers who want hybrid construction at a mid-range price point.

Firmness: Medium is the sweet spot
Side sleepers need a mattress that's soft enough to cushion the shoulders and hips but firm enough to keep the spine straight. Based on the standard 1-10 firmness scale, I recommend 4-6 (medium to medium-firm) for most side sleepers. If you weigh under 11 stone, aim for 4-5.
If you weigh over 14 stone, 5.5-7 gives you enough support to prevent the hips sinking too deep. A study in the Journal of Physical Therapy Science found that medium-firm mattresses produced the best spinal alignment in side sleepers compared to both firm and soft alternatives.
Construction: Why hybrid often wins for side sleepers
Hybrid mattresses - which combine pocket springs with foam or latex layers - tend to work best for side sleeping. The springs provide zoned support that adapts to the different weights of your shoulder, hip, and midsection, while the foam layer provides the pressure relief side sleepers need. Pure memory foam can also work well, especially for lighter side sleepers who want a more contouring feel, but it tends to sleep warmer and can make it harder to change positions.
Thickness: Look for at least 25cm
A mattress under 25cm thick rarely has enough comfort layer depth for side sleeping. You need at least 5-8cm of comfort material (foam, latex, or micro-springs) above the support core to allow your shoulder to sink in properly. Thinner mattresses bottom out at the shoulder, creating a pressure point that can cause numbness and tingling by morning.
Motion isolation matters for couples
If you share a bed, motion isolation becomes more important for side sleepers because you're already more sensitive to movement when sleeping in a curled position. Memory foam and hybrid mattresses both perform well here. Pocket spring mattresses with high spring counts (1,000+) also isolate motion effectively because each spring moves independently.
Trial periods: Don't skip them
It takes 2-4 weeks for your body to adjust to a new mattress, especially for side sleepers who are used to compensating for poor pressure relief. Every mattress on this list offers at least a 40-night trial, and most offer 100-200 nights. Use the trial period to evaluate how your shoulders and hips feel in the morning. If you're still waking up with numbness or stiffness after 4 weeks, the mattress probably isn't right for you.
Frequently Asked Questions
What firmness is best for side sleepers?
Medium to medium-soft (4-6 on the firmness scale) is generally best for side sleepers. This range provides enough cushioning to relieve pressure on the shoulder and hip while keeping the spine aligned. Side sleepers who weigh less than 11 stone typically need softer mattresses, while heavier side sleepers may prefer medium-firm.
Is memory foam or hybrid better for side sleeping?
Both can work well, but hybrids tend to be better for most side sleepers because they combine pocket springs for support with foam layers for pressure relief. Pure memory foam conforms closely to the body, which can help with pressure points, but it may sleep warmer and make it harder to change positions. Hybrids like the Simba Hybrid offer a better balance of comfort and support for most side sleepers.
Why do side sleepers need a different mattress?
Side sleeping concentrates body weight onto two small contact points: the shoulder and the hip. A mattress that is too firm creates pressure that can cause numbness, tingling, and pain in the arms and shoulders. A mattress that is too soft allows the hips and shoulders to sink out of alignment, straining the lower back. Side sleepers need a mattress that cushions these points while maintaining spinal alignment.
Can a mattress topper help a firm mattress for side sleeping?
A mattress topper can add 2-5cm of cushioning to a firm mattress, which may help if the mattress is only slightly too firm. A high-density memory foam or latex topper can relieve some shoulder and hip pressure. However, if the mattress itself is the wrong firmness level, a topper is a temporary fix. The underlying mattress still needs to provide proper support for your spine. See our best mattress toppers guide for recommendations.
How much should I spend on a mattress for side sleeping?
You can get a good mattress for side sleeping at every price point. The Silentnight 1200 Pocket at around ยฃ315 offers decent pressure relief with 1200 individual pocket springs. Mid-range options like the Simba Hybrid (ยฃ849) and Emma Premium (ยฃ749) provide the best balance of pressure relief and support. Premium options like the Tempur Sensation (ยฃ1,899) offer the most advanced pressure-relieving materials.
Do side sleepers need a special pillow too?
Yes. Side sleepers need a pillow with enough loft (height) to fill the gap between the ear and the shoulder. A pillow that is too flat lets the head drop downward, straining the neck. A pillow that is too thick pushes the head upward, also causing neck strain. Most side sleepers need a medium to high loft pillow. See our best pillows for side sleepers guide for specific recommendations.
Can side sleeping cause shoulder pain?
Side sleeping can cause shoulder pain if the mattress does not provide enough pressure relief at the shoulder joint. When the shoulder is pressed into a firm surface for 6-8 hours, it can compress the rotator cuff tendons and restrict blood flow. A mattress with good pressure relief at the shoulder zone prevents this by allowing the shoulder to sink into the comfort layer while keeping the spine straight.
If you already have shoulder pain, the Tempur Sensation provides the most effective pressure relief of any mattress We compared.
Final Verdict
After comparing 14 mattresses for side sleeping comfort, the Simba Hybrid Mattress is my top pick for most side sleepers in 2026. Its five-layer hybrid construction with 2,000+ micro-springs provides a precise balance of pressure relief and support, according to pressure-mapping tests - the shoulder zone sinks enough to prevent pain while the lumbar area stays properly aligned. The 200-night trial and 10-year guarantee make it a risk-free investment.
But the right mattress depends on your specific needs:
- Side sleeper with back pain? The Emma Premium has the best zoned lumbar support in our foam-mattress comparisons.
- Tight budget? The Silentnight 1200 Pocket delivers real pocket spring support and decent pressure relief for under ยฃ400.
- Chronic shoulder or hip pain? The Tempur Sensation offers the most advanced pressure-relieving material we've seen in 20 years of practice.
- Combination sleeper? The Otty Hybrid is the safest medium-firm all-rounder that works across multiple positions.
