Best pillows for side sleepers to ease neck and shoulder pain

We all know the feeling of desperately needing those precious hours of undisturbed rest, only to be thwarted by an uncomfortable pillow that leaves you with a stiff neck come morning. For the side sleepers among us (around half of adults), finding the best pillow for side sleeping isn't just about comfort – it's about preventing pain and stiffness by supporting your head and neck properly.

When you sleep on your side, your head, neck and spine need to stay in a straight line with your mattress. Without adequate support, your body can fall out of alignment, leading to those all-too-familiar aches in your neck, shoulders, hips and even knees. The right pillow makes all the difference, filling the gap between your shoulder and ear so everything stays comfortably supported throughout the night.

Thankfully, like mattress toppers and duvets, pillow technology has come a long way, with memory foam, latex and adjustable wool pillows that are specifically created for side sleepers - plus cooling options if you tend to overheat.

So, I’ve scoured the Mumsnet forums to find the pillows our community genuinely swears by, then cross-checked them against our top-rated guide, picks and to make sure they offer proper support as well as value for money. This guide brings you the very best pillows for side sleepers, as recommended by real parents who know exactly how precious good sleep is.

Best pillow for side sleepers, at a glance

How I’ve chosen

I've been down the pillow rabbit hole – looking at dozens of options and speaking to physios and sleep experts about what actually works for side sleepers – but the starting point was always real feedback from Mumsnet users.

First, I scoured the Mumsnet forums for honest recommendations from parents who genuinely use these pillows night after night, filtering for comments that mentioned side sleeping and relief from neck or shoulder pain. Then we sense-checked those favourites with sleep specialists and pillow designers, asking detailed questions about loft height, fill materials, pressure relief and how well each option keeps your head and neck aligned.

Every pillow featured here has been thoroughly road-tested by Mumsnet users, and I’ve looked at wider user reviews to assess multiple criteria. Wherever possible we’ve included multiple retailers (usually Amazon, Argos and the brand’s own site) and clearly labelled “Price at time of writing" so you can quickly compare deals before you buy.

Best pillows for side sleepers - a guide

What is the best pillow for side sleepers?

If you're a side sleeper, your pillow needs are quite specific. When your head hits that pillow each night, you need something with enough height and firmness to keep your spine properly aligned from head to hips. Too flat, and your neck drops down at an angle; too high, and you're forcing your head upward – both recipes for morning misery!

As Verity Kick, Marketing Director at Oak Tree Mobility, explains: "For side sleepers, it's important to choose a pillow that strikes the right balance between support and comfort to keep your spine aligned properly. A pillow with a medium to high loft (height) is ideal. This is because it helps fill the space between the head and shoulder, ensuring the neck stays straight and reduces strain on the spine."

Nils Stene, CEO of Norvegr, confirms this approach: "If you sleep solely on your side, we recommend a firm pillow if you want to use one pillow. Sleepers need a higher pillow to support the head, neck and align the spine."

Emily and Jonathan Attwood, founders of scooms, add: "Side sleepers often need a firmer, higher-loft pillow to maintain neck alignment, whilst stomach sleepers may benefit more from a softer, thinner pillow."

Material-wise, memory foam gives you excellent support, while latex offers similar benefits with more bounce. Traditional down or feather pillows can work well if they're firm enough but might need more regular plumping.

The right pillow should keep your head, neck and spine in a straight horizontal line – like an extension of your mattress. Your shoulders should sink into the mattress while your pillow supports your head at the perfect height. 

UK health guidance for neck pain often recommends using a low, firm pillow that keeps your head in line with your spine, rather than stacked pillows that push your neck out of position. If you’re waking up sore, try removing any extra pillows and switching to a single, supportive pillow designed for side sleepers to see if your symptoms improve.

What is the best height for a side sleeper pillow?

The magic number most sleep experts recommend is between 10 to 15cm (that's about four to six inches), but here's the thing: it really depends on your shoulder width.

Dr. Mahwish Dildar Abbasi, a dermatologist and aesthetics professional, confirms: "Side sleepers need more loft than back sleepers because the acromion creates a wider space. Most patients feel balanced with 10 to 12 cm of height in medium firmness latex or shredded memory foam that can be fluffed to fill that gap without tipping the head forward."

The golden rule is that your pillow should completely fill the gap between your ear and your mattress. Too low, and you'll get that horrible neck droop; too high, and you're forcing your neck upward at an awkward angle. 

Stene emphasises that "height is the key factor" for side sleepers, although he notes that this "looks different to everyone" based on body type. Kick adds that the ideal pillow height "helps fill the space between the head and shoulder, ensuring the neck stays straight and reduces strain on the spine."

Broader-shouldered folks generally need something closer to the 15cm mark, while more petite sleepers might find 10cm just right. The perfect height keeps your spine in a lovely straight line from the tailbone to the crown.

Adjustable pillows are absolutely brilliant for side sleepers – you can add or remove filling until you hit that sweet spot where your neck feels perfectly supported without any pressure points. Your shoulders should sink into the mattress while your head stays perfectly aligned.

How long should a pillow last?

As a rough guide, most experts suggest replacing your pillow every one to two years, or sooner if it’s gone lumpy or no longer springs back when you squeeze it. That way, you keep the loft you need for good alignment instead of slowly sinking into a tired, flat pillow.

Are memory foam pillows good for side sleepers?

The beauty of memory foam for side sleepers is how it creates that perfect support between shoulder and ear – it literally moulds to your head and neck, keeping your spine properly aligned instead of dropping at an awkward angle.

The Attwoods explain: "Memory foam pillows are designed to contour to the shape of your head and neck for tailored support. Ideal for those who prioritise spine alignment and pressure relief, they can be good for those who suffer from neck and back issues."

Andreea Costina, CEO of Achillea Beauty, offers a more technical perspective: "A pillow works well when its internal structure rebounds quickly yet yields just enough to cradle the skull. For that balance, I lean toward moulded latex or blended kapok and shredded memory-foam fill."

They can feel a bit brick-like initially, but give it a week to adjust. The firmer feel is exactly what side sleepers need to maintain that all-important height. Dr. Abbasi recommends "10 to 12 cm of height in medium firmness latex or shredded memory foam" as the sweet spot for most side sleepers.

Memory foam does retain heat more than natural options, so if you're a hot sleeper, look for ones with cooling gel or bamboo covers. And yes, they're pricier than supermarket options.

What to look for when buying a pillow for side sleeping?

First, height is absolutely crucial - you want something with a decent loft (about 10-15cm) to properly fill that gap between your shoulder and head. Too low and your neck drops down; too high and you're forcing it upward. Neither is good news for your spine.

The Attwoods suggest creating a checklist before you shop: "The key things to put on your checklist are: Support Needs (match the pillow firmness to your favourite sleeping position), Size and Fit, Filling Material, and Certifications and Accreditations."

Costina recommends starting "with material transparency. Look for GOLS-certified latex or CertiPUR-US memory foam to avoid residual solvents. Favour breathable covers woven from organic cotton at least 200 TC so sweat disperses rather than pools at the hairline."

Firmness is your next priority - medium-firm to firm is the sweet spot for most. Those super-soft pillows might feel lovely in the shop, but they'll have your neck screaming by morning.

Home improvement expert Justin Nielsen at Wolf River Electric adds practical advice: "When shopping, look for adjustability (removable filling), hypoallergenic materials, and breathable covers. Pillows generally last one to two years, depending on the material. If yours is lumpy or doesn't bounce back, it's time for a replacement."

Material-wise, memory foam and latex tend to work brilliantly for side sleepers, but if you're a hot sleeper, look for cooling technology or bamboo covers. Adjustable options are worth the extra pennies, as being able to add or remove filling until you hit that perfect height is a game-changer. 

Can a pillow help with side sleeper neck pain?

The right pillow isn't just a nice-to-have for side sleepers, it's essential.

Nielsen explains it perfectly: "For neck pain, a contoured memory foam pillow offers targeted support that aligns the spine. Side sleepers benefit from firmer pillows that fill the gap between the ear and shoulder, so consider a latex or hybrid pillow for this."

Here's why: when you sleep on your side with the wrong pillow, your neck ends up at an awkward angle all night long. Your spine is forced into an unnatural position, muscles tense up, and morning neck pain is inevitable. 

NHS guidance on neck pain also stresses the importance of supporting your neck in a neutral position with a firm pillow and avoiding awkward angles, which is exactly what a well-chosen side sleeper pillow aims to do.

Dr. Abbasi confirms this with clinical evidence: "Chronic neck pain improves when a pillow supports the curve at C-lordosis. In a crossover study, a spring-supported design reduced pain scores and disability after four weeks."

The answer is finding a pillow that fills that gap between your ear and shoulder. The Attwoods emphasise: "Your pillows should provide proper support and alignment for your head, neck and spine. Your shoulders shouldn't rest on the pillow as this can cause misalignment and place unnecessary strain on the neck."

You want something with enough height and firmness to keep your spine beautifully aligned. Memory foam pillows are brilliant for this as they mould to your exact shape without collapsing.

Nielsen adds a crucial reminder: "You spend nearly a third of your life sleeping, so don't skimp on quality. Test pillows in person where possible, or buy from retailers with strong return policies. A better pillow can make a world of difference in how you sleep, move, and feel."
