How Many Pillows Should You Sleep With?

Posted By: Layla

How many pillows should you sleep on at night? If you wake up with shoulder, back, or neck pain, your pillows might be to blame. Your pillow's main function is to keep your head and neck in proper alignment. Unfortunately, many people sleep with too many or too few pillows, which can cause pain in the morning.

How Many Pillows Should You Sleep With?

So, while your big pile of pillows might be comfortable when sitting in bed, you probably don’t need it to sleep at night. So you might be wondering, “How many pillows should I sleep with?” Ultimately, there is no one-size-fits-all solution to the pillow problem. Some people need only one comfortable pillow, while others need several.

Key Takeaways

  • Most people sleep best with 1-2 pillows, though your optimal number depends on your sleeping position. For example, side sleepers may need more support than back or stomach sleepers.
  • The key to choosing pillows is maintaining proper spinal alignment, not the quantity. A single high-quality pillow designed for your sleep position often works better than multiple standard pillows.
  • Strategic pillow placement, such as under the knees, between the legs, or under the pelvis, can provide additional support and improve sleep quality.
  • Replace your pillows every 1-2 years or sooner if you notice signs of wear like flatness, lumps, or persistent neck pain.

How Many Pillows Should You Sleep With at Night?

Most people sleep best with 1-2 pillows, though the ideal number depends primarily on your sleeping position and personal comfort needs. While many people’s nighttime routines consist of stacking or fluffing their pillows while reading or watching TV in bed, when it’s time to hit the lights, fewer pillows typically provide better sleep support.

The key to choosing the right number of pillows is maintaining proper spinal alignment during sleep. Much like how much sleep you need, how many pillows you should sleep with at night varies.

How many pillows should you sleep with?

In most cases, how many pillows you need will depend on your sleep position. For example, side sleepers need at least one pillow to keep their neck in proper alignment with their shoulders, while stomach sleepers need a flat pillow or no pillow to prevent neck pain in the morning. So, how many pillows should you sleep with under your head? Here are a few factors to consider:

Number of Pillows for Side Sleepers

Pillows for side sleepers

There are several pillows available on the market designed for side sleepers. How many pillows you should sleep with as a side sleeper depends on how thick your pillows are. For example, if you have a lofty pillow, you might only need one. However, if your pillows are flat, you might need multiple. What’s more important than the number of pillows is finding a pillow or a combination that will prevent you from putting too much stress on your shoulders as you sleep.

Additionally, side sleepers may benefit from an additional pillow between their knees to relieve pressure on the lower back and hips.

Number of Pillows for Stomach Sleepers

Stomach sleepers are at a pillow disadvantage because this is considered one of the worst sleeping positions. While it can improve digestion, keeping your head, neck, back, and hips in proper alignment is nearly impossible. However, if you can’t change your sleeping position, consider sleeping with a single, flat pillow underneath your head. Some stomach sleepers may feel even more comfortable without a pillow.

In addition to a pillow under the head, stomach sleepers should consider adding another under their pelvis to keep their lower back and hips in proper alignment.

Number of Pillows for Back Sleepers

Back sleepers can usually be comfortable with one pillow as long as they keep their heads in proper alignment. Also, your pillow shouldn’t be too lofty. Sleeping on your back is the best way to keep your neck, spine, and hips in proper alignment to reduce pain.

If you sleep on your back, you can improve spinal alignment by placing a pillow beneath your knees. When your knees are raised, it reduces pressure on your lumbar spine and helps keep your pelvis in a neutral position throughout the night. Choose a medium-firm pillow that won’t compress too much under the weight of your legs while still providing comfortable support.

Number of Pillows for Snorers

One downside of sleeping on your back is that back sleepers are more prone to snoring because this position relaxes the airways. However, snorers can prevent this problem and reduce the chances of waking up their spouse or partner by keeping their head elevated with an additional pillow. Of course, you should be careful not to prop your head up too much because this can force your head and neck forward, potentially causing strain. Other sleep positions don’t relax the airways as much, so if you snore, you might consider sleeping on your side instead.

Number of Pillows for Sleepers With Back Pain

If you experience back pain, your best sleeping position is either on your back or side. First, however, it’s crucial to find a pillow that keeps your body in proper alignment and possibly use one between your knees or under your body, depending on how you sink into your mattress.

If you experience regular back pain, consider strategically arranging pillows around your body depending on your sleep position. For example, if you sleep on your stomach, you can put an additional pillow under your pelvis. Meanwhile, if you sleep on your back, you can try elevating your legs by placing pillows under your knees.

How to Find the Right Pillow

Now that you have the answer to your question, “How many pillows should I sleep with?” it’s time to consider the type of pillow you use. While adding pillows can help keep your body in proper alignment, many are designed specifically based on your sleep position, so you may only need one high-quality and comfortable pillow to support your head and neck.

Unfortunately, many people don’t realize that they need a new pillow. If you’re waking up in pain, it might be obvious. However, buying a new pillow before yours starts causing problems is usually best. For example, if you notice lumps or bumps in your pillow, it may mean that, eventually, they’ll force your head out of alignment throughout the night. Additionally, if your pillow is no longer as fluffy, firm, or lofty as it once was, it’s time to get a new one before it starts causing pain. Of course, knowing how to wash pillows is crucial for preventing lumps and bumps! Still, pillows don’t last forever, so consider replacing yours every few years.

Factors to consider when buying a pillow

Wondering how to buy a pillow? Here are a few factors to consider when shopping for the best pillow:

  • Type of pillow: The type of pillow plays a crucial role in your sleep quality and ability to keep your body in proper alignment. Consider the different materials, such as down, memory foam, polyester, and latex. Each has its pros and cons. For example, down flattens easily but is soft. Meanwhile, memory foam pillows cradle your head and neck but may be less breathable, depending on the brand.
  • Pillow loft: Pillow loft refers to the height of your pillow when it’s lying flat. Standard lofts include low loft (under 3 inches), medium loft (3-5 inches), or high loft (over 5 inches). Your ideal loft depends on your sleeping position and body type. Side sleepers typically need a higher loft for shoulder clearance, while stomach sleepers benefit from a low loft to maintain spinal alignment.
  • Sleeping position: Finding the right pillow based on your sleeping position is crucial. Side sleepers need different pillows than back sleepers in terms of firmness and height. If you’re a back sleeper, your pillow should support your neck. Many people like contoured pillows that slope in the center and support the natural curvature of their necks. Meanwhile, side sleepers should have more support from their pillow, requiring them to be higher and firmer to prevent too much pressure on the shoulders and arms.
  • Neck and spine support: Your pillow should always support your neck and spine to keep it in proper alignment and prevent pain. Unfortunately, many pillows flatten easily and put your body in an uncomfortable position. For example, stomach sleepers shouldn’t sleep on a lofty, high pillow like side sleepers because it pushes their heads up and above their necks and shoulders.
  • Size: Pillows come in all shapes and sizes, with the most common being standard or queen. However, you can also find a king-sized pillow designed for extra-wide mattresses. Additionally, body pillows are designed to provide full-body support and comfort, especially for side sleepers. While the size of the pillow won’t affect your body’s alignment, it can affect sleep quality. For example, using a pillow that takes up too much space can make it challenging to get comfortable at night.
  • Temperature regulation: If you’re wondering how to prevent night sweats, consider your pillow. Some pillows absorb heat, which may keep your head too warm at night. If you sleep hot, consider a pillow made from breathable fabrics and materials that promote airflow to keep your head cooler.
  • Firmness: Firmness also plays a crucial role in supporting your head and neck during sleep. Side sleepers need firm pillows that won’t sink in as they sleep because they could put pressure on their neck, spine, and shoulders. Meanwhile, back sleepers can look for a pillow with medium firmness that cradles the head.
  • Trial period: A trial period is crucial when shopping for pillows because you won’t know if a pillow is right for you until you begin using it. Only purchase pillows from brands that allow you to try them for at least a few nights to determine if they’re right for you.

Types of Pillows and Their Functions

Different pillow materials and designs have distinct purposes, offering various levels of support, comfort, and durability. Understanding each type can help you choose the perfect pillow for your sleep needs. Here’s a breakdown of the most common pillow types:

  • Memory foam pillows: These pillows conform to your head and neck shape, providing consistent support throughout the night. Memory foam responds to your body heat, creating a custom cradle that helps maintain proper spinal alignment.
  • Kapok pillows: Made from natural tree fibers, kapok pillows offer a lightweight, silky feel similar to down but are plant-based and hypoallergenic. They provide adjustable support and excellent breathability for comfortable sleep.
  • Down pillows: Filled with soft duck or goose feathers, down pillows are known for their plush, moldable comfort. They’re incredibly soft and long-lasting, though they may need regular fluffing to maintain their loft.
  • Down alternative pillows: These synthetic pillows mimic the soft feel of down without using animal products. They’re generally more affordable and hypoallergenic, making them ideal for allergy sufferers and those looking for a more ethical pillow.
  • Body pillows: These full-length pillows provide support for your entire body. They’re especially beneficial for side sleepers, pregnant women, and anyone seeking extra comfort for their shoulders, hips, and knees.
  • Wedge pillows: These triangular pillows elevate your upper body or legs to help with specific health concerns. They can help reduce acid reflux, improve breathing, and can relieve back pain or swelling.
  • Cervical pillows: Designed specifically for neck support, these pillows feature a contoured shape that follows your neck’s natural curve. They help maintain proper neck and spinal alignment and can relieve neck pain.

Frequently Asked Questions

How do you find the right number of pillows for you?

Finding your ideal pillow arrangement starts with your sleeping position. Experiment with different combinations while paying attention to how your body feels. Your head should stay aligned with your spine, and you shouldn’t experience any pain or discomfort. Start with one high-quality pillow and add support pillows under your knees, between your legs, or under your lower back as needed for comfort.

When should you replace your pillows?

It’s recommended to replace your sleeping pillows every 1-2 years. However, the actual lifespan of your pillow depends on its material, quality, and how well you care for it. So, how long do memory foam pillows last? While a quality memory foam pillow can last for 2 or even 3 years, that doesn’t necessarily mean you should keep yours that long. For any pillow, consider these key signs that indicate it’s time for a replacement:

  • Flatness: Your pillow no longer regains its shape after being folded or compressed, indicating it has lost its supportive properties.
  • Neck or back pain: Waking up with new or increased neck or back pain could mean your pillow isn’t providing proper support anymore.
  • Stains: Visible yellowing or staining that persists even after washing suggests it’s time for a fresh start.
  • Headaches: Regular morning headaches might indicate your pillow isn’t supporting your neck and head alignment properly.
  • Odor: Persistent unpleasant smells that don’t disappear after washing signal it’s time for replacement.
  • Allergies: If you experience an increase in allergy symptoms, it could mean your pillow has accumulated dust mites and allergens.
  • Lumps: Noticeable lumps or uneven filling distribution means the pillow’s internal structure has broken down.

Is it better to sleep with one or two pillows?

Sleeping with two pillows may be ideal if you’re a side sleeper, but that’s not always the case. The ideal number of pillows depends primarily on your sleeping position and the pillow’s loft. One high-quality pillow with a proper loft is often sufficient for back sleepers, while side sleepers might need one thick pillow or two thinner ones to achieve proper neck alignment. Focus on ensuring neutral spine alignment rather than focusing on a specific number of pillows.

Wrapping Up: How Many Pillows Should You Sleep With?

While the number of pillows you sleep with affects how much support your head and neck get, it’s more important to find a single pillow that’s right for you. Believe it or not, you don’t need multiple pillows; a high-quality pillow based on your sleeping position and individual preferences should be enough to prevent aches and pains from strain at night.

Additionally, don’t forget to strategically place pillows around your body for ultimate support and comfort. Adding pillows under your pelvis, between your knees, and under your legs can keep your body in proper alignment all night.
