The Coop Home Goods Original Adjustable pillow suits most side sleepers who want to tune loft by adding or removing fill, the Purple Harmony suits buyers who want a cooler, springy grid material and a choice of loft heights, and Tempur-Pedic adjustable or contoured models suit people who like memory foam support. Side sleepers need enough height to fill the gap between the ear and the shoulder, so loft and firmness matter more than any single brand.

How to Choose a Side Sleeper Pillow
Loft: The Gap Between Ear and Shoulder
When you lie on your side, your head sits above the mattress by roughly the width of your shoulder. A pillow that is too thin lets the head drop toward the mattress, and one that is too tall pushes it upward. Broader shoulders and firmer mattresses generally call for higher loft, while narrower shoulders and softer mattresses call for lower loft. Adjustable pillows let you tune this, which is the main reason Coop and the Tempur-Adapt ProAdjust rank highly.
Firmness
Side sleepers generally prefer medium to firm, since a soft pillow compresses and loses support during the night. Purple Harmony users in reviews suggest the medium loft for side sleeping, and one dissenting reviewer at Pillow Specialist questioned whether a non-adjustable pillow suits side sleepers at all. If you are between sizes, adjustable fill gives you room to change.
Fill Types
- Shredded memory foam: moldable and adjustable, with a slightly dense feel. Used by Coop.
- Solid memory foam or contour: consistent shape, sometimes with a neck curve.
- Latex: springy and breathable, often firmer.
- Down and feather: soft and moldable, but may lose loft and need fluffing.
- Polyester fiberfill and down alternative: budget-friendly and washable, though they compress faster.
- Gel grid materials: Purple’s Grid Hex design that reviewers describe as cool and bouncy.
Temperature
Reddit users quoted in roundups say Tempur-Pedic pillows can sleep hot, while grid and latex designs often feel cooler. Cooling claims come from makers, so treat them as the maker’s description and read reviews from people who sleep warm.
Pillow Size and Pairing
Pillows come in standard, queen and king. Make sure the pillowcase fits, and pick the size that matches your bed width so there is room for two. Side sleepers who hug a pillow may also like a body pillow or a knee pillow between the legs.
Care and Materials
- Memory foam pillows are usually not machine washable; spot clean the foam and wash the cover as the label states.
- Many shredded foam pillows have a removable cover that can be washed. Check the label.
- Use a pillow protector to keep the pillow clean and extend its life.
- Replace pillows when they flatten, lump or no longer support your head.
- Look for the certifications listed by the maker, such as CertiPUR-US for foam or Oeko-Tex for textiles, and read exactly what each covers.
If you wake up with persistent neck pain, numbness or tingling, see a doctor rather than relying on pillow changes. This guide is not medical advice.
Brand Notes
Coop Home Goods
HGTV picked the Original Adjustable as its Best Overall for side sleepers and CNN Underscored named it the best for side sleepers. A Reddit-based roundup reports mostly positive comments but some quality concerns on newer units. The Eden has a cutout and sits at a higher budget tier.
Purple Harmony
HGTV named it Best Splurge. Sleepopolis found it well suited to back and side sleepers, including combination sleepers. It comes in low, medium and high lofts, and the premium tier price reflects the Grid Hex material.
Tempur-Pedic
HGTV chose the TEMPUR-Neck for contour, and CNN recommends the Tempur-Adapt ProAdjust. Reviewers caution that the TEMPUR-Cloud is too low for most side sleepers. Models are premium in budget tier.
Pick X If You Need Y
| Pick this | If you |
|---|---|
| Coop Original Adjustable | are unsure about loft and want to tweak fill |
| Coop Eden | want a neck cutout and adjustable fill |
| Purple Harmony (medium or high loft) | sleep warm and like a springy, cool feel |
| Tempur-Adapt ProAdjust | like memory foam and want adjustability |
| TEMPUR-Neck | prefer a shaped contour |
| Budget fiberfill or down alternative | need a low-cost pillow for guests |
Budget Tiers
Budget pillows use polyester or basic foam and are fine for guest rooms but flatten sooner. The mid-range tier includes adjustable shredded memory foam such as Coop’s original. Premium includes Purple Harmony, Tempur-Pedic and latex or down options. Since adjustability is often what makes a pillow work for side sleeping, a mid-range adjustable can beat a more expensive fixed-loft model.
Alternatives
- Latex pillows: durable and cool, often firmer.
- Buckwheat pillows: adjustable and firm, with a distinctive sound and feel.
- Down pillows with a firm fill power: luxurious and fluffable.
- Knee pillows: help align hips and legs for side sleepers.
Fitting a Pillow at Home
Many makers offer a trial period, which is useful because pillow comfort is personal. Give a new pillow a couple of weeks, as your neck and shoulders can take time to adjust to a different height. During that period, notice whether your head sits level with your spine when you lie on your side, whether your shoulder feels crowded, and whether you wake with your arm tucked under the pillow. If you do, a higher loft or a firmer fill may suit you better. Small adjustments to fill level on an adjustable pillow often solve the problem without buying a new one.
Mattress and Shoulder Width
The mattress matters as much as the pillow. On a soft mattress, the shoulder sinks in, so a lower pillow can work. On a firm mattress the shoulder stays up, so you generally need more loft. Broad shoulders need more height than narrow ones. If you change mattresses, expect to re-tune your pillow too. Combination sleepers who move between back and side positions often prefer a medium loft with a bit of give.
Common Mistakes
- Choosing a pillow that is too thin because it feels soft in a store.
- Stacking two soft pillows instead of one supportive one, which can collapse under weight.
- Ignoring the cover fabric and temperature preferences.
- Keeping a flat pillow long past its useful life.
Pillow Care Routine
Fluff adjustable and fiber pillows daily, rotate them end to end, and wash removable covers every few weeks or as the label states. A protector under the pillowcase helps keep sweat and oils away from the fill. If you sleep warm, choose a breathable cover fabric and avoid trapping heat with thick quilted protectors. When you travel, bring your own pillow if it compresses easily, since a familiar height can make a big difference to comfort in a hotel bed.
Frequently Asked Questions
What loft is best for side sleepers?
Medium to high loft generally suits side sleepers because it fills the gap between ear and shoulder. Broader shoulders usually need more. An adjustable pillow makes it easier to dial in.
Is memory foam good for side sleepers?
Many reviewers recommend shredded or adjustable memory foam because it holds shape and supports the neck. It can sleep warm for some people, so consider a cooler fill if that matters.
How often should I replace my pillow?
Replace it when it no longer holds its shape or you notice lumps, flatness or discomfort. Use a protector and follow the care label to extend life.
Can I wash a memory foam pillow?
Usually not. Spot clean the foam and wash only the removable cover as the label states. Machine washing can damage the foam.
Is an adjustable pillow worth it?
Often yes for side sleepers, since your ideal height depends on shoulder width and mattress softness. You can remove or add fill until it feels right.
Should I see a doctor about neck pain from sleeping?
If pain is persistent, severe, or comes with numbness or tingling, see a doctor. Pillows are comfort products and not treatments.
