Side sleeping can leave your head and neck at an awkward angle if your pillow is too low, too high, or too soft. The right choice depends on your shoulder width, preferred firmness, and how much support you need—not just a pillow’s shape. These five options include contoured memory foam designs and an adjustable-fill pillow, so you can compare different ways to find a comfortable fit.
Our top pick is the Cozyplayer Ultra Pain Relief Cooling Pillow for its contour design and multiple ways to adjust its height. If you prefer to customize firmness by adding or removing fill, the Sidney Sleep pillow is a different style worth considering.

|---|---|---|---|
| Cozyplayer Ultra Pain Relief Cooling Pillow | Hollow contour memory foam | Rotate pillow or remove bottom insert | Side sleepers seeking a shaped neck cradle |
| Latree 5X Pain Relief Cervical Neck Pillow | Butterfly-shaped contour memory foam | Rotate pillow to change contour height | People who want arm space and neck support |
| Sidney Sleep Side and Back Sleeper Pillow | Shredded memory foam fill | Add or remove fill | Sleepers who want to customize loft and firmness |
| Osteo Cervical Pillow | Hollow contour memory foam | Rotate pillow or remove insert | Sleepers who want two height options and a contoured shape |

Our Picks: Best The Perfect Pillow For Side Sleepers reviews
Cozyplayer Ultra Pain Relief Cooling Pillow: Best Overall Contour Design
The Cozyplayer is a contoured memory foam pillow with a hollow center intended to cradle your head. Its raised areas are shaped to support the neck, shoulders, and arms, which may appeal if a traditional rectangular pillow leaves you searching for a comfortable position.
The design offers two ways to change the feel: rotate the pillow 180 degrees for a different contour height, or remove the bottom insert. That flexibility can help you fine-tune the loft, though a shaped pillow will feel different from a soft, fill-based bed pillow. The product description also identifies a breathable memory foam core and a cooling pillowcase; cooling effects can vary from person to person.
Compared with the Sidney Sleep pillow, Cozyplayer offers a more structured neck cradle rather than adjustable loose fill. It may suit side sleepers who want contouring, but it is not the most adaptable choice if you prefer to change the pillow’s firmness by adding or removing material.
Pros:
- Contoured design includes a hollow head cradle and shaped support zones.
- Height can be adjusted by rotating the pillow or removing the insert.
- Memory foam core and a breathable, cooling-style pillowcase.
- Designed with side, back, and stomach sleeping positions in mind.
Cons:
- The fixed contour may take time to get used to if you prefer a traditional pillow.
- The cooling feel and ideal height will depend on personal preference.
Verdict: Choose the Cozyplayer if you want a contoured side-sleeper pillow with more than one way to adjust its height.
Latree Cervical Neck Pillow: Best for a Butterfly Shape with Arm Space
Latree’s pillow has a butterfly-shaped contour with a hollow area intended to cradle the head. Its shaped edges include areas for the neck and shoulders, plus armrests that may give you somewhere to position an arm without pushing it beneath the pillow.
The pillow uses open-cell memory foam and a 3D mesh pillowcase, according to the product description. Its height can be changed by turning it around, but the description does not list a removable insert. That makes it simpler to adjust than a pillow with several removable parts, but less customizable than the Cozyplayer or Osteo.
Latree is described as suitable for side, back, and stomach sleepers. In practice, a butterfly contour is a more specific feel than a standard pillow, so consider whether you like having a defined place for your head and neck. Its certification claims are listed by the manufacturer; check the product listing for current details.
Pros:
- Butterfly contour includes a hollow head area and shaped support zones.
- Armrest areas may be useful for side sleepers who position an arm near the pillow.
- Rotating the pillow offers a choice of contour height.
- Open-cell foam and a mesh-style cover are designed to support airflow.
Cons:
- Height adjustment is limited to rotating the pillow.
- The sculpted shape may not suit sleepers who prefer a flat, flexible pillow.
Verdict: Latree is a good option to consider if you want a shaped cervical pillow with dedicated arm space and a simple height adjustment.
Sidney Sleep Pillow: Best for Adjustable Fill and Loft
Unlike the molded contour pillows in this list, the Sidney Sleep pillow uses adjustable memory foam fill. You can add or remove fill to change the pillow’s height and firmness, and the product description says it includes a storage bag for excess material. This lets you make changes gradually rather than choosing between only two set heights.
The pillow is designed for side and back sleepers and comes in a king size listed as 19 by 36 inches. Its removable cover is described as machine washable. The adjustable design may be helpful if you are unsure what loft works for you, though finding the right amount of fill can take some trial and adjustment.
Choose Sidney Sleep if you prefer a more traditional pillow feel and want to customize the amount of support. If you want a defined neck cradle or a hollow center, one of the contour models may be a closer match.
Pros:
- Add or remove memory foam fill to customize loft and firmness.
- Includes a storage bag for extra fill.
- Removable cover is described as machine washable.
- King-size option is listed at 19 by 36 inches.
Cons:
- Adjusting the fill takes more effort than rotating a contoured pillow.
- It does not have a molded hollow head cradle or dedicated armrest zones.
Verdict: Pick Sidney Sleep if adjustable fill matters more to you than a sculpted cervical shape.
Osteo Cervical Pillow: Best for Two Contour Heights
Osteo is a hollow-center memory foam pillow designed to cradle your head and support the neck. The product description says the shape is intended for side, back, and stomach sleepers, and the sculpted contours give it a more structured feel than a standard bed pillow.
For height adjustment, you can rotate the pillow to use the opposite side or remove the insert at the bottom. This is useful if one height feels too tall or too low, though the adjustment options are set by the pillow’s design rather than by adding or removing fill. The 3D mesh cover is described as breathable, and the listing states that the foam is CertiPUR-US certified and the textile is OEKO-TEX approved.
Osteo has a similar adjustable contour approach to Cozyplayer. Both offer a hollow center, rotation, and a removable insert, so your choice may come down to the shape and feel you prefer. Neither design can guarantee relief from neck discomfort; if pain persists, consider discussing it with a qualified health professional.
Pros:
- Hollow center and contoured shape are designed to cradle the head and neck.
- Offers two height options through rotation and a removable insert.
- Breathable 3D mesh cover is described as helping air circulate.
- Designed for several sleep positions, including side sleeping.
Cons:
- Its molded shape may feel unfamiliar if you are used to a conventional pillow.
- It offers fewer firmness adjustments than a pillow with removable fill.
Verdict: Osteo is worth considering if you want a contoured pillow with a hollow center and two ways to change its height.
Bespillow Cervical Pillow: Best for a Washable Cover and Two Set Heights
Bespillow is a butterfly-shaped memory foam pillow with two different side heights: the product description lists one side at 5.5 inches and the other at 3.7 inches. Turning the pillow lets you choose between those options. Unlike adjustable-fill pillows, it does not require you to open the pillow and change its contents.
The pillow has a removable, machine-washable cover, a useful feature if you want a straightforward way to care for the pillowcase. The product description says the foam has CertiPUR-US and OEKO-TEX certifications. It is also presented as suitable for side, back, and stomach sleeping, though people who need a very specific loft may prefer a model with more adjustment options.
Compared with Latree, Bespillow gives specific height measurements for each side and lists a washable cover. Latree also has a butterfly shape and armrest areas. Bespillow may be the better fit if a washable cover and two stated heights are your priorities.
Pros:
- Two height options are listed: 5.5 inches and 3.7 inches.
- Removable cover is described as machine washable.
- Contoured butterfly design is intended to support the neck and head.
- Memory foam is described as CertiPUR-US and OEKO-TEX certified.
Cons:
- Height choices are limited to the two sides; the fill is not adjustable.
- The contoured shape may not suit sleepers who prefer a soft, unshaped pillow.
Verdict: Consider Bespillow if you want a contoured pillow with two stated height choices and a machine-washable cover.
How to Choose a Pillow for Side Sleeping
Match the Pillow Height to Your Shoulder Width
When you lie on your side, the pillow fills the space between your head and the mattress. A pillow that is too low may let your head tilt toward the mattress, while one that is too high may push it upward. Your shoulder width, mattress firmness, and body shape all affect the loft that feels comfortable. If you are uncertain, an adjustable-fill pillow gives you room to make smaller changes; a contoured pillow usually offers fewer, defined height choices.
Choose Between Contoured Foam and Adjustable Fill
Contoured pillows such as Cozyplayer, Latree, Osteo, and Bespillow have shaped areas intended to cradle the head and support the neck. This can feel supportive if you like your head to settle into a defined position, but the shape may take getting used to. Sidney Sleep uses adjustable fill instead, so you can alter the pillow’s height and firmness. That flexibility comes with the extra step of opening the pillow and adjusting its contents.
Consider How Much Adjustment You Need
Some pillows offer just one or two fixed options; others allow more fine-tuning. Cozyplayer and Osteo can be rotated and have a removable insert. Latree changes height by rotating the pillow. Bespillow provides two sides with stated heights. Sidney Sleep lets you add or remove fill, which offers a different kind of adjustment. Think about whether you want a quick change or the ability to gradually customize the pillow.
Check the Shape and Space for Your Arms
Side sleepers often have a preferred way to position their arms. A butterfly-style pillow may include areas intended for arm placement, as Latree’s description notes, while another contour design may focus more on the head and neck. If you usually tuck an arm under your pillow, check the shape carefully and consider whether its contours leave enough room to move comfortably.
Look at Cover Care and Breathability
A removable, washable cover can make routine care easier. Bespillow and Sidney Sleep describe machine-washable covers, while the other product descriptions highlight breathable mesh or cooling-style fabrics. These features may matter if you sleep warm, but a cooling fabric cannot ensure that everyone will feel cool. Check the care instructions on the product listing before washing any cover.
Give a New Contour Shape Time, but Pay Attention to Comfort
A sculpted pillow can feel quite different from a traditional pillow. If you choose one, use its adjustment options to find a comfortable height and notice whether the shape works with your usual position. Do not assume a pillow will treat a medical condition or prevent pain. If neck or shoulder pain is ongoing or severe, seek advice from a qualified health professional.
Frequently Asked Questions
What type of pillow is best for side sleepers?
There is no single best pillow for everyone. Many side sleepers look for enough height to fill the gap between the head and shoulder, plus a shape or fill that feels supportive. The right choice depends on your body, mattress, and comfort preferences.
Are contour pillows always better than traditional pillows?
No. A contour pillow provides a defined shape that some people may find comfortable, while others prefer the flexible feel of a standard pillow. If you are unsure, consider whether you want a molded neck cradle or the ability to adjust loose fill.
How can I tell if my pillow is too high or too low?
Notice how your head and neck feel when you lie on your side. If the height feels uncomfortable or your head seems pushed upward or allowed to dip toward the mattress, try another height or adjust the fill if the pillow allows it. Comfort is personal, and the right loft may take some experimenting.
Which pillow in this list has the most adjustable fill?
The Sidney Sleep pillow lets you add or remove memory foam fill to change its height and firmness. Cozyplayer and Osteo also have adjustment options, but they rely on rotating the pillow and removing an insert rather than changing loose fill.
Can these pillows be used for back sleeping?
The product descriptions identify these pillows as options for more than one sleeping position, including back sleeping. Your comfort may depend on the height and shape that work for you. Check the product details for the specific model before choosing.
Are cooling pillowcases guaranteed to keep you cool?
No. Some of these pillows have mesh or cooling-style covers intended to support airflow or a cooler feel, but people experience temperature differently. Bedroom temperature, bedding, and personal comfort can also affect how warm a pillow feels.
Can a pillow relieve neck pain?
A supportive pillow may feel more comfortable for some people, but no pillow can guarantee pain relief. Persistent, severe, or worsening neck pain is best discussed with a qualified health professional.
Final Recommendation
For a shaped pillow with multiple height adjustments, start with the Cozyplayer Ultra Pain Relief Cooling Pillow. Choose Sidney Sleep if you would rather fine-tune loft and firmness by adding or removing fill. Osteo and Bespillow offer clear alternatives for shoppers who want a contoured shape, while Latree stands out for its butterfly design and armrest areas. Compare the adjustment style and cover-care details before choosing the pillow that best fits your sleep habits.
