Expert Recommended Mattresses for Side Sleepers
Sleep is the ultimate indulgence. And for side sleepers, choosing the best mattress is a balance of firmness and comfort. Our experts have curated their recommended mattresses for side sleepers to bring clarity to your decision.

The principle of alignment for side sleepers
In the side-sleeping position, alignment is key. Your mattress should let your shoulders and hips settle to maintain the line of your spine. Without this give, a rigid surface forces your body into a strained arc. While a mattress lacking support allows your midsection to sink, compressing the very posture you seek to maintain.
Selecting your ideal resistance
To achieve a neutral spine, the best type of mattress for side sleepers generally falls within the medium to firm range. This spectrum allows your shoulder and hip to settle, while preventing your lumbar region from sagging. Any further refinement is determined by your unique size and shape, which is why it’s so important to test a mattress before you buy one.
For example, if you have a lighter frame, a medium-soft tension mattress is best for you. Heavier builds often find more comfort in a medium-firm tension mattress. This provides the structural integrity required to keep the spine level, ensuring the mattress supports you rather than simply yielding to you.
"At Feather & Black, we often see side sleepers gravitate toward a firmer feel in hopes of better support, but the reverse is usually true. You need enough 'give' in the comfort layers for your shoulder to settle. If your mattress doesn't yield, your muscles spend the night fighting for a neutral position."

Addressing pain through zoned support
Pain may be a signal that your body requires a more responsive mattress. This is where zoned support becomes essential. By tailoring the tension across the surface, through a combination of nested springs and the right fillings, we ensure that your mattress gives in the right places, and supports where it needs to.
For side sleepers navigating back pain, Louise suggests prioritising zoned spring systems. These provide a softer surface for the shoulders and a more resolute support for the lumbar region, preventing the hammock effect that strains the lower back.
We also recommend ensuring your mattress has sufficient depth - typically 25cm or more - to prevent it from bottoming out against the support core, a common cause of joint ache. Responsive comfort layers such as horsetail or high-density microsprings allow side sleepers to feel supported, not pressured.
The materials of rejuvenation
The best mattress for side sleepers is defined by its fillings. To help you find your perfect mattress, it’s helpful to understand how different materials respond to your shape.
Hemp is used in almost all of our Flaxby and Harrison Spinks mattresses. From a side sleeping perspective, hemp is extraordinarily useful. As one of the strongest natural fibres, hemp is a sustainable way to add insulation, moisture-wicking, and most importantly, support. Hemp adds structure to a mattress, which prevents sagging, a key cause of pressure-based pain for side sleepers.
A good mattress for side sleepers combines the resilient strength of pocket springs with these comfort layers. A traditional pocket-sprung mattress uses individual coils that move independently, allowing the heavier points of the shoulder to settle deeply while the waist remains perfectly buoyed. By selecting materials that harmonise with your natural movement, you ensure your sanctuary is as functional as indulgent.
"When choosing materials, consider how you move at night. If you tend to turn frequently throughout the night, the responsive 'push-back' of latex or a hybrid model will serve you better than a deep-sink memory foam, which can sometimes feel too restrictive for an active side sleeper."
- Louise Silver
Horsetail, which you’ll find in our Vispring mattresses, is another of nature’s strongest materials. Hand-teased into tight, springy coils, natural horsetail creates a layer of bouncy support that absorbs the weight of a side sleeper effortlessly.
Microsprings are a sustainable variation of memory foam. They serve the same function: pressure relief, individual support, and a subtle sink that adapts to your shape. Unlike memory foam, which retains heat, microsprings act as tiny bellows, moving air — and thus heat and moisture — away from your body to maintain a comfortable temperature.
Alternatively, latex provides a similar contouring effect for side sleepers but with more bounce and a responsive lift. It’s naturally breathable, encouraging better airflow to ensure your sanctuary remains temperate throughout the night.

We bring clarity to your selection process, ensuring your choice harmonises perfectly with your physical needs and the character of your bedroom. These selections from our mattress range are specifically curated to provide the sophisticated architecture required for a perfect night’s rest.
The Owen Mattress
The Owen pairs a supportive pocket-sprung core with deep layers of natural wool and cotton. For the side sleeper, this combination is particularly effective; the wool provides a breathable, temperature-regulating loft that yields to the shoulder, while the cotton ensures a crisp, structural integrity. It’s an ideal choice for those who seek a soft, airy mattress that remains resolutely supportive at its core.
The Coleridge Mattress
The Coleridge is designed for side sleepers who appreciate the individual support of nested pocket springs. By nesting the springs, we create a more concentrated support system that contours to the body's curves with greater intimacy. This mattress is particularly well reviewed by side-sleepers, as the natural fillings work in harmony with the springs to provide a refined level of pressure relief and excellent comfort.
Flaxby Platinum Eclipse
The Flaxby Platinum Eclipse combines mohair and silk with support hemp and over 15,000 pocket springs. This unique blend offers independent motion that’s vital for side sleepers. This ensures that when your hip settles into the mattress, the surrounding springs remain uncompressed to support the curve of your waist. Finished with a pillow top, this indulgent mattress is for those who demand sumptuous comfort without having the hassle of flipping it.
Vispring Heybrook
For the most discerning side sleeper, the Vispring Heybrook represents the pinnacle of mattress perfection. Hand-tufted and filled with Vispring’s legendary vanadium steel springs, it offers a bespoke level of comfort. The Heybrook uses generous layers of British wool and cotton to create a high-loft surface that effortlessly hosts your profile, virtually eliminating the pressure points that lead to restless tossing and turning.
Completing the picture
Choosing the correct mattress is the best way to improve your sleep, but the final result depends on the harmony of your entire bed. To ensure your selection performs to its full potential, consider the following refinements.
The importance of a supportive base
A mattress requires a compatible base to maintain its structural integrity. For side sleepers, a sprung divan base can offer an extra degree of responsive support, allowing the mattress to contour even more deeply to your profile. A bed frame with a slatted base is sometimes criticised for lacking support and creating sags. This is not true. Well-produced slatted bases have gaps for improved airflow, but never so many gaps that it doesn’t support the mattress.
Cases where a mattress sags on a slatted base are usually due to the slats shifting or breaking, or the mattress not having a strong enough core. Built well, a slatted base can be the perfect base for a mattress. Whichever you choose, ensure the proportions and materials of the frame harmonise with the sensory character of your room.
Pillows that bridge the gaps
The alignment of your spine does not end at the shoulders. To maintain a truly neutral posture, a side sleeper requires a pillow with a higher loft to fill the gap between the ear and the mattress. Without this support, the neck is forced into an unnatural angle, undoing the work of even the finest mattress.
"A side sleeper's pillow is just as critical as the mattress. If your head tilts toward the mattress, you’ll wake with neck tension regardless of how good your bed is. Aim for a loft that keeps your nose perfectly aligned with the centre of your chest.”
