Memory Foam Pillows

If you like the feeling of sinking into your pillow like it’s giving you a gentle nod of approval, a memory foam pillow might be your match. It moulds to your head and neck, offering personalised support.

Pros:
✅ Moulds to your shape for personalised comfort
✅ Great for side and back sleepers
✅ Available in cooling gel varieties

Cons:
❌ Can trap heat without cooling features
❌ May feel too firm for some stomach sleepers
❌ Off-gassing smell when new

Hollowfibre Polyester Pillows

If you love a soft, cloud-like feel without sacrificing support, hollowfibre polyester pillows could be your go-to.

Made with recycled polyester and designed to retain pillow loft, these pillows are hypoallergenic, breathable, and ideal for those who want fluff without the fuss.

Pros:
✅ Excellent loft and airflow
✅ Hypoallergenic and planet-conscious
✅ Resists clumping thanks to silicone-coated fibres

Cons:
❌ Less contouring than memory foam
❌ May need fluffing over time
❌ Not as long-lasting as latex or down

Pillow advisor tip: If you’re after a lofty, breathable option that’s also eco-friendly, a pillow like our Loft Pillow hits the sweet spot.

Latex Pillows

Latex pillows bring a springy, slightly bouncy feel to bedtime.

They’re known for being incredibly durable and resistant to dust mites (no thanks, allergies). Plus, they stay naturally cooler than regular memory foam.

Pros:
✅ Naturally cooler and breathable
✅ Durable and long-lasting
✅ Hypoallergenic properties

Cons:
❌ Can feel too firm for some sleepers
❌ More expensive than polyester or microfibre options
❌ Natural latex scent (usually fades)

Gel-Infused Pillows

If you wake up feeling like you’ve spent the night in a sauna, gel-infused pillows might be your saving grace.

They combine memory foam or fibrefill with cooling gel layers to help regulate temperature.

Pros:
✅ Actively cools and disperses heat
✅ Good support for hot sleepers
✅ Available in various firmness levels

Cons:
❌ Can still trap heat without proper airflow design
❌ Some types feel heavy
❌ May have initial off-gassing smell

Feather and Down Pillows

Light, fluffy, and timeless. Feather and down pillows have been around for generations—and for good reason.

They’re adjustable, meaning you can squash and shape them however you like.

Pros:
✅ Lightweight and mouldable
✅ Offers luxurious softness
✅ Long lifespan with proper care

Cons:
❌ Requires regular fluffing
❌ Not ideal for allergy sufferers
❌ Can flatten over time

Pillow advisor tip: If you love the traditional feather feel, stick to it—but 100% feather pillows tend to work best for back or stomach sleepers. For a bit more softness and better all-round support, a feather and down blend usually makes a smarter pick.

Polyester Microfibre Pillows

Affordable and easy to care for, polyester microfibre pillows are a popular pick.

They’re soft and squishy—but don’t expect them to last forever.

Pros:
✅ Inexpensive and widely available
✅ Machine washable
✅ Lightweight and soft

Cons:
❌ Tends to flatten quickly
❌ Less breathable than natural materials
❌ Shorter lifespan overall

Buckwheat Pillows

Fancy something a little different? Buckwheat pillows are filled with tiny hulls that move and shift to cradle your head.

They offer brilliant airflow (hello, cooler nights) but can feel a bit firm at first.

Pros:
✅ Adjustable fill for personalised comfort
✅ Excellent airflow and cooling
✅ Natural and eco-friendly material

Cons:
❌ Can feel too firm for some sleepers
❌ Heavier than traditional pillows
❌ Noisy when shifting at night

Bamboo Pillows

Bamboo pillows have exploded in popularity—and not just because they sound fancy.

Bamboo covers or blended fillings often feel ultra-soft and naturally breathable.

Pros:
✅ Naturally breathable and moisture-wicking
✅ Eco-friendly and sustainable
✅ Hypoallergenic properties

Cons:
❌ Quality varies (some “bamboo” blends aren’t pure)
❌ Can be pricier than basic fibre options
❌ Needs careful washing to maintain softness

What Pillow Filling is Best for Sleeping Styles?

There’s no one-size-fits-all pillow. (If only it were that easy.)

The right filling depends a lot on how you sleep — and what your body needs to feel supported through the night.

Let’s break it down:

Side Sleepers

Best fillings: memory foam, latex, feather and down mix

For side sleepers, “maintaining horizontal alignment of the spine in the side position while utilizing the most suitable pillow is essential” as referenced in a 2023 study published in Applied Sciences.

So, they often require a pillow with a higher loft to bridge the gap between the head and shoulders, maintaining spinal alignment. Fillings that offer both support and adaptability are ideal.

Pillow fillings for side sleepers:

  • Memory foam: Moulds to the shape of your head and neck, providing consistent support.
  • Latex: Offers a balance of firmness and responsiveness.
  • Feather and down mix: Adjustable and can be fluffed to the desired loft.

Back Sleepers

Best fillings: memory foam, latex, feather and down

Back sleepers need a pillow that supports the natural curve of the neck without tilting the head too far forward.

This natural curve is known as cervical lordosis—and keeping it properly supported during sleep is essential for comfort and spinal health. And so, choosing a pillow that maintains this natural curve helps protect against stiffness, discomfort, and long-term posture problems.

Pillow fillings for back sleepers:

  • Memory foam: Provides contouring support to the neck and head.
  • Latex: Maintains shape and offers consistent support.
  • Feather and down: Soft and adjustable, allowing for personalized comfort.

Stomach Sleepers

Best fillings: feather and down, polyester microfibre, bamboo

Stomach sleepers need a softer, thinner pillow to prevent neck strain and maintain spinal alignment.

For stomach sleepers, a low-loft pillow helps maintain a neutral spine position, reducing the risk of neck discomfort.

Pillow fillings for stomach sleepers:

  • Feather and down: Easily compressed, allowing for a flatter profile.
  • Polyester microfibre: Soft and low loft, suitable for stomach sleeping.
  • Bamboo: Naturally breathable and soft, offering gentle support.

Combination Sleepers

Best fillings: latex, shredded memory foam, feather and down

If you’re the type who switches sides, curls up, stretches out, and somehow ends up diagonally across the bed, you’ll need a pillow that can keep up with you.

A versatile option that adjusts easily to different sleeping positions is the way to go.

Top pillow fillings for combination sleepers:

  • Latex: Naturally responsive, offering support that moves with you.
  • Shredded memory foam: Lets you adjust loft and firmness for ever-changing sleep styles.
  • Feather and down: Easy to squash and reshape, perfect for midnight position changes.

How to Choose Pillow Material That’s Right for You

With so many choices floating around (pun intended), picking the right pillow material can feel a bit like finding a needle in a very fluffy haystack.

But don’t stress—we’re here to make it simple.

1. Think About Your Sleeping Position

Your favourite sleeping position should guide your choice of pillow material.
Different materials support different positions better.

  • Side sleepers: Need higher pillow loft and firm support—memory foam, latex, or feather and down mixes are great options.
  • Back sleepers: Do best with medium support—latex, memory foam, or adjustable feather and down pillows.
  • Stomach sleepers: Need a soft, low-loft pillow—think bamboo or soft microfibre.

2. Prioritise Breathability if You Sleep Hot

No one wants to wake up feeling like their head’s been slow-cooked.

If you tend to overheat during the night, go for materials that allow airflow.

What pillow material stays the coolest? 

✅ Latex

✅ Bamboo

✅ Hollowfibre polyester pillows

3. Consider Allergies or Sensitivities

If you’re prone to sniffles, sneezes, or itchy eyes, choosing the right material matters even more.

What is the healthiest pillow filling for sensitive sleepers?

Materials resistant to dust mites, mould, and bacteria are hypoallergenic options like:

✅ Latex

✅ Bamboo

✅ Hollowfibre polyester

4. Match Material to Your Desired Feel

Some people want a cloud. Others want a sturdy stack of support.

Knowing what feels “right” can narrow down your choices fast.

What is the softest pillow material?

✅ Feather and down mixes

✅ Bamboo as they tend to feel softer and squishier

Need firmer support? Memory foam or latex will be more up your alley.

5. Think About Hair and Skin, Too

Pillows don’t just affect your sleep—they impact your hair and skin health as well.

Which pillow material is best for hair?

Bamboo and silk-covered pillows are gentler on hair, reducing frizz and breakage.

Which material pillow cover is best for skin?

Breathable fabrics like bamboo or silk help keep your skin cool and irritation-free.

Pillow advisor tip: Natural fibres like bamboo or silk not only feel luxurious but can make a real difference for sensitive skin and hair health.

6. Durability and Care

Some pillows demand a relationship… and not the good kind.

Think about how much time you’re willing to spend fluffing, washing, or replacing your pillow.

✅ Memory foam and latex tend to last longer without losing shape.

✅ Feather and down pillows may need regular fluffing and careful washing to maintain loft.

Pillow advisor tip: If low-maintenance is your style, look for machine-washable options like hollowfibre polyester pillows.

Final Thoughts: Finding Your Perfect Pillow Match

Choosing the right pillow material is all about matching your sleep style, comfort needs, and what feels good night after night. Once you know what to look for, finding the perfect fit becomes simple.
