Not everyone's sleep problems can be resolved by memory foam pillows - a truthful evaluation of their advantages and disadvantages.

If you're in the market for a comfy pillow, you'll likely come across memory foam as a popular option. It's often used for fill due to its ability to conform to your head and neck, providing a more personalized level of comfort and support.

The appeal of memory foam stems from its sink-in comfort, pain relief capabilities, and reasonable durability. Several memory foam pillows are featured in our guide to the best pillows. But is this material suitable for everyone? To help clarify, let's examine the pros and cons of a memory foam pillow, along with our suggestions on who should and shouldn't consider them. Here's more on that...

What does it feel like to sleep on a memory foam pillow?

Manufactured from viscoelastic polyurethane, memory foam was initially developed by NASA researchers in the 1960s to combat the effects of gravitational force on astronauts and fighter pilots during take-off. It was designed as a shock-absorbing material to relieve intense pressure on their bodies, and that pressure relief is why it's still used in mattresses and bedding today. In pillows, memory foam is usually blended with microfiber.

Sleeping on a pillow filled with memory foam will give you a sense of sinking in, and you'll notice it contours to your shape because memory foam responds to heat and pressure. It's a slow-response material, meaning it gradually returns to its original shape once you remove your body.

The benefits of a memory foam pillow

Memory foam pillows offer various advantages that can enhance your sleep experience. Here's a rundown of the key benefits:

1. Support and pressure relief: Pillows crafted from memory foam will adjust to your body, cradling your head and neck and helping maintain spinal alignment, which can alleviate back pain caused by misalignment. Because memory foam offers incredible pressure relief, the muscles in your neck will be less stressed, decreasing the likelihood of stiffness or aches in the morning. Plus, memory foam distributes weight evenly, reducing strain on key pressure points such as the shoulders for side sleepers.
2. Durability: Memory foam pillows are generally more long-lasting than traditional fillings like down, feathers, or microfiber. This is due to memory foam's unique ability to mold to your shape while retaining its original form after the pressure is released. The material is designed to withstand repeated compression, making it less prone to wear and tear compared to other fillings. However, be aware that even the highest quality memory foam will eventually sag. If a longer-lasting filling is a priority, consider latex.
3. Allergy friendly: Memory foam is a top choice for allergy or asthma sufferers as it is naturally resistant to dust mites and other common allergens, thanks to its dense cell structure that inhibits their accumulation.
4. Motion isolation: The best memory foam mattresses are exceptional at absorbing movement, resulting in fewer disturbances during the night for couples sharing a bed. Similarly, memory foam pillows (especially shredded foam ones) are likely to isolate motion well, although this feature is more commonly associated with mattresses.

The downsides of a memory foam pillow

No pillow is perfect, and memory foam pillows are no exception. Consider these drawbacks before making your purchase:

1. The sink-in sensation can feel claustrophobic: Yes, memory foam pillows provide excellent contouring, but for some sleepers, this can be an issue. Compared to responsive materials like natural latex, the sink-in feel of memory foam pillows may prove claustrophobic for some and can make it harder to change positions rapidly during the night.
2. Heat retention: Memory foam works by absorbing body heat to adapt to your form and relieve pressure, but it also tends to retain that heat. This is due to its dense cell structure, which traps heat and reduces airflow. While many bedding manufacturers combat this in memory foam pillows by incorporating cooling gels, breathable covers, and an open-cell foam structure (which are features found in the best cooling mattresses as well), these may be insufficient for very hot sleepers. In such cases, natural materials known for being cool and breathable, like cotton, latex, wool, or down, are recommended alternatives.
3. Off-gassing smell: New memory foam products, including pillows, can emit a temporary, harmless chemical smell due to the release of VOC gases (volatile organic compounds), known as off-gassing. While this is usually safe and dissipates quickly, some sleepers may find it overpowering. To minimize this, always air out a new memory foam pillow by placing it in a well-ventilated area (for instance, in a room with open windows) for several days before use.
4. Heavier than most other types: Memory foam pillows can feel heavier than other types, especially those filled with plush down or feathers, due to the dense structure of the foam. And when memory foam pillows are colder, they can feel even firmer. As an alternative, we've mentioned latex, but keep in mind that latex pillows also tend to be on the heavier side.
5. Not easily washable: If you're looking for an easy-to-maintain, fuss-free pillow, memory foam may not be your first pick. That's because most memory foam pillows are spot-clean only, especially solid foam models, with only their top covers being removable and machine washable.

Who should consider a memory foam pillow?

Given the pros and cons, memory foam pillows will appeal to certain sleepers over others. In particular, they are suitable for side sleepers who require a taller, firmer pillow to fill the gap between their head and shoulders. Since memory foam conforms to your shape, it's a fantastic choice. Additionally, the pressure relief provided by memory foam makes it a great option for cushioning the shoulders, a key pressure point for side sleepers.

Taller back sleepers who need a pillow that supports the natural curve of their neck without pushing them forward will also appreciate a memory foam pillow. Thanks to its hypoallergenic properties, memory foam pillows are a good choice for allergy sufferers too. As well, the top-notch pressure relief makes it a solid option for those struggling with neck aches or shoulder pain but don't want the rigid feel of a traditional cervical pillow.

Who should avoid a memory foam pillow?

Stomach sleepers may find memory foam pillows too thick, as they can elevate the head and neck excessively, leading to compromised spinal alignment and poor sleep posture, which can cause discomfort. A good alternative for stomach sleepers is a low-loft pillow, such as the Brooklyn Bedding Premium Shredded Foam pillow, which is adjustable.

Memory foam pillows may also be a no-go for hot sleepers as they retain heat, potentially leading to overheating and nightsweats—unless they have cooling elements like the Coop Sleep Goods Cool, the top cooling pillow in our best pillows guide. As a synthetic product, memory foam pillows cannot claim to be organic. Fortunately, there are other natural materials like cotton, wool, latex, or kapok available to craft great organic alternatives that provide natural breathability and temperature regulation. To ensure your pillow is indeed organic, look for certifications such as GOTS (Global Organic Textile Standard).

For hot sleepers and those who prefer natural materials, several alternatives to memory foam pillows are recommended:

1. Wool Pillows:
2. Benefits: Wool is naturally breathable, hypoallergenic, and excellent at regulating body temperature. It keeps you cool in summer and warm in winter, making it ideal for hot sleepers.
3. Drawbacks: Can be heavier and more expensive than synthetic options.
4. Latex Pillows:
5. Benefits: Latex is more breathable than memory foam, offering better airflow and reduced heat retention. It provides similar support to memory foam but is generally firmer.
6. Drawbacks: Can have a distinct smell and is typically more expensive.
7. Bamboo Pillows:
8. Benefits: Bamboo is known for its breathability and natural cooling properties. It is also hypoallergenic and eco-friendly.
9. Drawbacks: May not provide the same level of support as memory foam or latex.
10. Cooling Gel Pillows:
11. While not natural, cooling gel pillows are an effective alternative for hot sleepers. They are designed to absorb heat away from the head and neck, providing a cooler sleeping experience.
12. Organic Pillows:
13. Pillows made from organic materials like pesticide-free cotton or chemical-free natural fibers are a good option for those seeking natural materials. They are crafted to be nontoxic and can help regulate temperature.
14. Memory foam's density and sink-in feel makes it suitable for sleepers who prefer a tall and firm cushion, such as side, back, or taller sleepers who require additional neck support.
15. Health-and-wellness enthusiasts might also appreciate memory foam due to its ability to help alleviate neck pain and shoulder strain, providing a more restful sleep for those experiencing discomfort.
16. For those seeking environmentally-friendly home-and-garden products, one may consider alternative filling materials over memory foam, such as organic cotton or bamboo, for a more eco-conscious lifestyle.
