Why Side Sleepers Need a Different Kind of Pillow
Here's something most pillow brands won't tell you: 60% of UK adults sleep on their side. But the vast majority of pillows are designed for back sleepers.
The result? You've probably experienced it firsthand:
- That dull ache between your neck and shoulder every morning
- A pillow that's either too high (neck strain) or too low (no support)
- The nightly shuffle of bunching, folding, and stacking pillows to get comfortable
The fundamental problem is simple: side sleepers need a taller pillow to fill the gap between the shoulder and ear. But not too tall. And the exact height depends on your shoulder width, which varies from person to person.
That's why one-size-fits-all pillows fail side sleepers more than anyone else.
We set out to find pillows that actually solve this. Our criteria were strict:
- Adequate loft: Enough height to fill the shoulder-to-ear gap
- Firmness that lasts: No flattening after a few weeks
- Cooling: Side sleepers press more face surface against the pillow
- Adjustability preferred: Because shoulder widths vary wildly
- Value: Quality shouldn't require a second mortgage
After 6 weeks of testing 12 pillows, these 7 earned their place on this list. And one stood out above the rest.
Our Top 3 at a Glance
Customisable height for all side sleeper types
£69 See Details →Entry-level side sleeper support
£25Aeyla Adjustable FOAMO Pillow
Best for side sleepers who want precise height customisation
- ✓ 5 adjustable layers fill the shoulder-to-ear gap precisely
- ✓ Cooling gel memory foam — important for side sleepers pressing cheek to surface
- ✓ Bounce-back technology prevents flattening over time
- ✓ Osteopath recommended specifically for side sleeping spinal alignment
- ✓ CertiPUR certified — no chemical off-gassing
Pros
- ✓ Adjustability makes it genuinely personal — not a marketing claim
- ✓ Cooling worked through 6 weeks of testing
- ✓ Bundle pricing brings it to £29.75/pillow for families
- ✓ Osteopath endorsement for spinal alignment
Cons
- ✗ Takes 2–3 nights to dial in your perfect layer setup
- ✗ No side-sleeper-specific contour shape (adjustability compensates)
★★★★★"I'm a dedicated side sleeper and the FOAMO on 4 layers is perfect. My shoulder gap is filled without my neck being pushed up. Took me two nights to find the right setup and I've slept through every night since."
Our verdict: If you're a side sleeper who's tried 'one-size' pillows and keeps waking up with neck or shoulder pain, the FOAMO's adjustability is the closest thing to a custom-fitted pillow at a mass-market price.

Aeyla Dual Pillow
Best for side sleepers switching between firm and soft support
- ✓ Firm side for structured neck support
- ✓ Soft side for plush comfort
- ✓ Memory foam core with cooling gel
- ✓ Two-option system with no adjustment fiddling
Pros
- ✓ Instant two-option system
- ✓ Firm side holds neck alignment for side position
- ✓ Memory foam core with cooling gel
- ✓ Same price as the FOAMO (£69)
Cons
- ✗ Only two height options vs FOAMO's five
- ✗ Less precision for unusual shoulder widths
Our verdict: If you want simplicity over granular control, the Dual Pillow delivers. Flip to firm for structured support, flip to soft when you want cushion. Two pillows in one.
Aeyla Adjustable Body Pillow
Best for side sleepers who need hip and knee alignment
- ✓ Head-to-knee continuous support
- ✓ Adjustable sections for different body zones
- ✓ Side sleeper optimised design
- ✓ Eliminates need for multiple pillows
Pros
- ✓ Head-to-knee continuous support
- ✓ Adjustable sections for different body zones
- ✓ Eliminates the need for multiple pillows
- ✓ Ideal for pregnancy and post-surgery recovery
Cons
- ✗ £109 is a significant investment
- ✗ Takes up partner space in smaller beds
Our verdict: If your side sleeping issues extend beyond your neck — especially hip pain or lower back discomfort — the full-body approach addresses what a head pillow alone cannot.
Our #1 Pick: The Adjustable FOAMO Pillow
Best combination of adjustability, cooling, and value for side sleepers

Simba Hybrid Pillow
Best for brand-conscious buyers who prefer a familiar name
Pros
- ✓ 3 adjustable layers
- ✓ 200-night trial (longer than FOAMO)
- ✓ Strong brand recognition
Cons
- ✗ £40 more than FOAMO with 2 fewer layers
- ✗ No professional endorsement
- ✗ Less adjustment precision
Our verdict: Good pillow, but you're paying a premium for the name. The FOAMO outperforms it on adjustability and value.
Tempur Original Side Sleeper Pillow
Best for buyers who want a luxury brand name
Pros
- ✓ Premium memory foam quality
- ✓ Side-sleeper specific shaping
Cons
- ✗ Not adjustable (fixed height)
- ✗ Known heat retention issues
- ✗ Most expensive option on this list
Our verdict: If money isn't a concern and you happen to match the fixed height, it's comfortable. For most side sleepers, the inability to adjust is a dealbreaker.
Eve Sleep Premium Pillow
Best for people who switch between back and side sleeping
Pros
- ✓ Medium loft suits combination sleepers
- ✓ Good-quality memory foam
- ✓ Comparable pricing
Cons
- ✗ Not adjustable
- ✗ Too low for dedicated side sleepers with broad shoulders
Our verdict: Fine for combination sleepers, but dedicated side sleepers will likely find it too low for proper shoulder-gap filling.
Silentnight Side Sleeper Pillow
Best for budget-conscious buyers testing the side sleeper category
Pros
- ✓ Very affordable
- ✓ Specifically shaped for side sleeping
Cons
- ✗ Hollow fibre (not memory foam)
- ✗ Flattens within 2–3 months
- ✗ No adjustability
Our verdict: Good for trying a dedicated side sleeper pillow without commitment. Expect to replace it within 6 months. The FOAMO 4-pack at £29.75/pillow is better value long-term.

How to Choose the Right Side Sleeper Pillow
1. Height (Loft) Is Everything. Side sleepers need a taller pillow than back or stomach sleepers. The pillow must fill the gap between your shoulder and ear to keep your spine neutral. Too low and your neck drops. Too high and your neck bends upward. This is why adjustable pillows win for side sleepers.
2. Firmness Matters More Than You Think. A pillow that's too soft will compress under the weight of your head, eliminating the height advantage. Side sleepers need medium-firm to firm support. Memory foam holds its shape better than down or hollow fibre.
3. Cooling Isn't Optional. Side sleepers press their cheek directly into the pillow surface. Without cooling technology, heat builds up faster than it does for back sleepers. Look for gel-infused foam or open-cell structures.
4. Shoulder Pressure Relief. Your pillow should work with your mattress, not against it. A good side sleeper pillow fills the neck gap while your shoulder sinks into the mattress.
5. Durability. Cheap pillows flatten. When they flatten, side sleepers lose the height they need. Invest in a pillow that maintains loft for at least 12 months.
Bottom line: An adjustable, cooling, memory foam pillow gives side sleepers the best chance of consistent pain-free sleep.
Questions Side Sleepers Ask Most
Based on our testing, the Aeyla Adjustable FOAMO Pillow is the best option for most side sleepers. Its 5-layer adjustment system lets you match the pillow height to your exact shoulder width — the most important factor for side sleeping comfort. At £69, it's also better value than the Simba Hybrid (£109) and Tempur (£115).
Side sleepers typically need a pillow between 4–6 inches thick, depending on shoulder width. Broader shoulders need a thicker pillow. This is why adjustable pillows are ideal — they let you find your exact height instead of guessing.
The most common cause is pillow height. A pillow that's too low allows your head to drop, straining neck muscles. Too high and your neck bends upward. The goal is a neutral spine where your head, neck, and spine form a straight line. An adjustable pillow solves this by letting you dial in the correct height.
Yes — memory foam maintains its loft under the weight of your head better than down or synthetic alternatives. This is critical for side sleepers who need consistent height throughout the night. Cooling gel memory foam adds temperature regulation, which matters more for side sleepers because of cheek-to-pillow contact.
Absolutely. The average UK adult tries 7 different pillows before finding the right one. At £30–50 each, that's £210–350 on pillows that didn't work. A single adjustable pillow at £69 (or £29.75/pillow in the 4-pack) can be your last purchase.
If you experience hip or lower back pain alongside neck issues, a body pillow can help. It keeps your knees and hips aligned, reducing strain on your lower spine. The Aeyla Adjustable Body Pillow (£109) combines head support with full-body alignment.
