Best Pillows for Side Sleepers

Side sleeping is New Zealand’s most common sleep position. But if you wake up with a stiff neck, a sore shoulder, or pins and needles in your arm, your pillow isn’t doing its job. For side sleepers, the right pillow fills the gap between your neck and mattress to keep your head, neck, and spine in a healthy, straight line. This guide will explore how to choose a pillow that supports you, doesn’t cause pain, and gives you the sleep you deserve.

Why choosing the right pillow matters for side sleepers

The right side sleeper pillow provides the essential loft and support to bridge the gap between your neck and the mattress, preventing your head from dropping too low or craning too high. A poor pillow choice leads directly to poor spinal alignment, forcing your neck, shoulders, and back into strained positions all night. This is a primary cause of morning aches and chronic pain, and can contribute to pressure points at your shoulder and hip, restricting circulation and causing numbness.

Evaluation criteria for side-sleeper pillows

To find your perfect side sleeper pillow match, consider these four key criteria. The best pillows for side sleepers excel in support, loft, material, and shape, working together to support your head and neck.

Support & firmness considerations

The ideal pillow for a side sleeper offers medium to firm support. It should feel resilient and supportive enough to cradle your head without completely collapsing under the weight. A soft pillow won’t maintain alignment, leading to neck strain, and one that’s too firm can create uncomfortable pressure. The goal is a pillow that holds its shape to keep your neck neutrally aligned with your spine throughout the night.

Loft (height) explained for side sleepers

Loft refers to a pillow’s thickness or height. For side sleepers, a higher loft will fill the gap between the neck and mattress. This is also partially dependent on your build – people with broader shoulders will need more pillow to fill the bigger gap. And your mattress plays a role: a plusher mattress may allow for a slightly lower loft, while a very firm mattress often requires a higher one to fill the space adequately. A pillow with insufficient loft will cause your head to tilt down toward the mattress, throwing your spine out of alignment.

Pillow materials compared

Different materials offer distinct feels and benefits:

• Memory Foam & Gel Foam: Excellent for contouring and pressure relief. They mould to the shape of your head and neck, providing personalised support. Gel-infused varieties, like Sleepyhead’s FusionGel, help dissipate heat for a cooler sleep.
• Natural Latex: Offers responsive, buoyant support. It contours without sinking deeply and is naturally breathable and durable.
• Natural Fill (Wool, Silk): Provides a softer, plush feel with good breathability. The Sleepyhead Luxury Wool & Latex pillow, for instance, combines wool’s comfort with a supportive latex core for side sleepers.

SmartFibre (Recycled Materials): A sustainable, resilient, and hypoallergenic option. Pillows like the Sleepyhead Evolve come in high-profile options suitable for side sleeping.

Shape and design features

Innovative shapes can enhance support:

• Contoured Pillows: Feature a curved design with a lower area in the centre for the head and raised sides to support the neck, promoting ideal alignment.

• Shoulder Cut-Outs: Some ‘cervical’ pillows are designed with an ergonomic cut-out or recessed edge. This allows your shoulder to nestle into the pillow, preventing it from being pushed uncomfortably upward and ensuring your neck stays level.

How to choose a pillow for side sleepers

Start by considering your dominant sleep position (side), any pain points (neck, shoulder), and personal preferences (cooling, eco-friendly materials). Use the criteria above to narrow your search. When testing a pillow, lie on it in your usual side-sleeping position. Your spine should feel like a straight, horizontal line from your head down through your hips. There should be no gaps under your neck, and your head shouldn’t angle up toward the ceiling. The right pillow feels comfortably supportive immediately.

Our top picks: Sleepyhead pillows for side sleepers

Best side sleeper pillow for neck pain

For side sleepers with neck pain, contouring support and proper loft are super important. A pillow that cradles the natural curve of your cervical spine helps relieve tension and allows muscles to relax overnight. Look for a pillow with a medium-firm to firm feel that provides gentle support under the neck without over-extending it. Pillows with ergonomic shapes, like Sleepyhead’s FusionGel Contour Pillow or Memory Foam Contour Pillow, are designed to maintain this head-neck-shoulder alignment, offering targeted relief for aching necks.

Quality sleep shouldn’t break the bank. For a budget-friendly option that doesn’t compromise on support for side sleepers, consider the Evolve SmartFibre Pillow.

Pillow care, longevity, and health tips

To protect your investment and ensure ongoing support, use a washable pillow protector as a first line of defence against oils, sweat, and allergens. Follow the manufacturer’s care instructions: most removable covers can be machine-washed regularly. Even with great care, pillows lose their supportive properties. Plan to replace your pillow every 1-2 years. Tell-tale signs it’s time for a new one include persistent odours or stains, visible flattening or lumps, and waking up with aches or pains.

Enhance your sleep with the right pillow for side sleepers

Choosing the correct pillow is the simplest yet most effective change you can make to improve your sleep quality as a side sleeper. It’s the foundation for spinal alignment, the solution to neck and shoulder pain, and the key to waking up refreshed.

FAQs – best pillows for side sleepers

What type of pillow is best for side sleepers?

 Side sleepers typically do best with a medium-firm to firm pillow that has a higher loft (height). Materials like contoured memory foam, latex, or high-loft down-alternative fibres are excellent choices as they provide the necessary support to keep the head and neck aligned with the spine.

Do side sleepers need two pillows?

 Not necessarily at the head, but strategic use of a second pillow can improve your comfort. Placing a pillow between your knees helps keep your hips and spine aligned, reducing lower back strain. Some side sleepers also benefit from hugging a pillow for upper body support.

How thick should a pillow be for side sleepers?

 The ideal thickness is approximately 10 to 15 cm, but it depends heavily on your shoulder width. Broader shoulders require a higher loft to fill the gap. The pillow should be thick enough so your head lies level with your spine, not tilted down toward the mattress or pushed upward.

Is memory foam good for side sleepers?

Yes, memory foam is often an excellent choice for side sleepers. Its contouring properties provide personalised support and pressure relief for the head and neck. For those who sleep warm, look for ventilated or gel-infused memory foam options (like Sleepyhead’s FusionGel) that enhance breathability and cooling.
