How To Sleep on a Pillow Properly: Tips by Sleep Position

How To Properly Sleep on a Pillow
The correct way to sleep on a pillow is to have just enough elevation to keep your spine neutral. This will keep your neck properly aligned with the rest of your body and reduce pressure as you sleep, preventing you from waking up with neck and shoulder pain.¹

If you tend to wake up with neck or shoulder pain, the issue may be your pillow or the way you are sleeping on it. Sleeping on the wrong pillow type or sleeping on a pillow the wrong way can leave you feeling tired in the morning.

The answer to how to sleep on a pillow depends on your sleeping position, since the best placement of your pillow for neutral spinal alignment depends on how you sleep.

Read along to learn how to best sleep on a pillow according to your sleep position and other pillow placement tips.

Side Sleepers

A side sleeper often prefers their left or right side instead of sleeping on their back or stomach for most of the night. There are a few variations of this position, and proper support is crucial to making sure you don’t wake up with neck pain or shoulder pain from sleeping on your side.

Here are some general pillow recommendations for this sleep position, but keep in mind that what works best for you comes down to personal preference.

• Best pillow: The best pillow for side sleepers is a medium to tall pillow or a body pillow for total body alignment. We recommend the following: 
  • Purple Freeform™ Pillow 
  • Purple DreamLayer™ Pillow
  • Purple Harmony™ Pillow (medium or tall) 
• Pillow placement: If you sleep on your side, your pillow should be high enough to cushion the space between your head and neck. Filling this gap will help maintain your spine’s natural curvature, reducing pressure on your head and neck².
• Tip: Side sleepers may want to sleep with a second pillow between their legs, as this extra cushioning can keep your knees properly stacked on top of each other. This will keep your hips and spine properly aligned, reducing pressure and the risk of body pain while sleeping³.

Back Sleepers

Sleeping on your back is most recommended by sleep experts since it’s the easiest way to keep your spine in a neutral position. However, it’s still important to make sure your head and neck are elevated properly to prevent a stiff neck.

These pillow suggestions typically work well for back sleepers, but remember the choice ultimately depends on your personal preference.

• Best pillow: A medium to low height pillow is going to be the best option for back sleepers. The following are ideal options: 
  • Purple Freeform™ Pillow
  • Purple DreamLayer™ Pillow
  • Purple Harmony™ Pillow (medium or low)
• Pillow placement: Placing your head on a sufficiently lofty pillow can keep your head, neck, and shoulders properly aligned. Ideally, your head shouldn’t sink too deeply into your pillow, as this may increase your discomfort and risk of developing sleep apnea⁴.
• Tip: Back sleepers may want to try sleeping with an extra pillow under their knees for better spinal alignment.

Stomach Sleepers

While sleeping on your stomach isn’t generally recommended, there are ways to minimize negative effects — starting with your pillow. As with back and side sleepers, the best pillow choice for stomach sleepers depends on individual preference.

• Best pillow: Pillows with low heights are the best option for stomach sleepers. We suggest these options: 
  • Purple Freeform™ Pillow
  • Purple DreamLayer™ Pillow
  • Purple Harmony™ Pillow (low)
• Pillow placement: Too much pillow fullness and height can raise your head to an uncomfortable angle, forcing you to strain your neck while sleeping. 
• Tip: People who sleep on their stomachs should consider adding an extra pillow under their pelvis or abdomen. This helps your back stay in a neutral position while you rest on your stomach, reducing stress on your spine⁵.

Combination Sleepers

If you find yourself moving around throughout the night, you need a pillow that can adapt to those changing needs. Ultimately the best pillow for you depends on your unique needs, but here’s what generally works best for combination sleepers.

• Best pillow: The best pillow for combination sleepers is made with flexible materials that will adapt to their changing positions. Here are our recommendations:
  • Purple Freeform™ Pillow: This is the most customizable option, as you can mold and shape the pillow to your preferred shape and height.
  • Purple DreamLayer™ Pillow: This pillow can be adjusted to a high, medium, or low height.
• Pillow placement: Because combination sleepers are prone to tossing and turning throughout the night, an adjustable pillow can offer the right middle ground for providing support to their changing head and neck placements as they sleep. 
• Tip: Combo sleepers who prefer back and side sleeping positions may want to opt for a medium to tall pillow, while those who find themselves sleeping on their stomachs may want a medium to low pillow. Evaluate which positions you most commonly find yourself in throughout the night and adjust accordingly.

Sleeping With a Pillow Between Legs: Benefits & Best Practices

When lying on your side, placing a pillow between your legs helps maintain proper spinal alignment by preventing the upper leg from pulling the spine out of position. It reduces stress on the lower back, hips, and knees for a more comfortable and supportive sleeping position. 

A few other benefits include: 

• Joint support: The pillow provides support to the knees and ankles, reducing pressure on the joints. This can be particularly helpful for those with arthritis or joint pain.
• Pain relief: By reducing nerve compression, sleeping with a pillow between your knees can contribute to pain relief, especially for conditions like sciatica⁶. 
• Improved circulation: Proper leg and spinal alignment can enhance blood circulation, reducing the likelihood of numbness or tingling in the legs.
• Prevention of knee-on-knee contact: Avoiding direct contact between the knees prevents irritation and rubbing, particularly for those who experience discomfort due to skin-on-skin contact.

To make the most out of sleeping with a pillow between your legs, choose a pillow size and feel that provides adequate support. One great option is the Purple Harmony™ Anywhere Pillow. It’s small enough to tuck between your knees while also having the right amount of bounce and support. 

Additionally, ensure the pillow is placed between your knees and thighs rather than directly under your knees for optimal alignment.

How To Use a Pillow for Pain Relief

The strategic use of a pillow can transform your quality of sleep and alleviate pain. Here are various ways to place pillows depending on your type of pain.

Pillow Placement for Back Pain

Curious about how to position a pillow for lower back pain? To start, it’s best to sleep on your back if you have back pain. If you still find this uncomfortable, try a medium to low loft pillow under your head and a pillow under your knees. 

For side sleepers, a medium to tall pillow under your head as well as a pillow in between your knees can help relieve back pain. For additional support, try placing a rolled-up towel under your waist⁷.

Stomach sleeping is the least conducive position to ease back pain. But if this is the only way you can sleep, try placing a pillow under your pelvis to help align your spine and relieve pressure.

Pillow Placement for Neck Pain

When it comes to neck pain, it’s less about how to position your pillow for neck pain and more about ensuring you have the right pillow loft for adequate support. The correct pillow height for you will keep your neck parallel to the mattress, not sinking downward or angled upward.
Additionally, a pillow with extra neck support is recommended⁸. The Purple Freeform™ Pillow has specially designed Neck Roll Chambers to offer custom, targeted support just for this purpose.

Pillow Placement for Pregnancy

To sleep better when pregnant, many people find using a body pillow can offer additional support to their hips and legs. Sleeping on your side is recommended to enhance circulation and facilitate oxygen delivery to the baby. Using a body pillow can help natural back or stomach sleepers from unintentionally rolling onto your stomach or back throughout the night.
