Buying a pillow and case together means you get a fill and a cover fabric that were designed for each other, instead of guessing whether an old pillowcase will fit a new pillow properly. This matters whether you're setting up a new bedroom, replacing one worn-out pillow, or shopping for a 2-pack set for a guest room. If you're furnishing the whole room at once, you can shop the Luxury Trio Bedding Set for a coordinated look.
This guide walks through the fill types, cover fabrics, sizes, and specialty options available so you can match a pillow to how you actually sleep. For a ready-made pairing, the Black & White Comfort Bundle is a popular starting point.
Guide compiled by the Beddora bedding team, based on standard Canadian bedding sizing and common fill material properties. For more on why that matters when choosing a brand, read our brand trust and confidence guide.
Pillow vs Pillowcase vs Pillow Cover vs Pillow Protector
These four terms get used loosely, but each one does a different job:
-
Pillow: The insert itself, made of a fill material (memory foam, down alternative, cotton, feather) inside a base fabric shell.
-
Pillowcase: The washable, everyday layer that slips over the pillow for sleeping, usually cotton, bamboo, silk, or satin.
-
Pillow cover: A more decorative or heavier-duty cover, often used on accent pillows rather than sleeping pillows, and often closed with a zipper.
-
Pillow protector: A hidden barrier layer, usually zippered and sometimes waterproof, worn underneath the pillowcase to block allergens, dust mites, and spills before they reach the insert.
A typical setup layers these: protector closest to the pillow, pillowcase over that for sleeping comfort, and a decorative pillow cover or sham added on top for styling. For a deeper breakdown of pillowcase and pillow cover terminology specifically, see our pillow covers and pillowcases guide.
What Pillow Fill Is Best for Your Sleep Position?
The fill inside a pillow controls support level, breathability, and how long it lasts, and different fills suit different sleep positions. Side sleepers generally need firmer, more consistent support, while back and stomach sleepers usually do better with a softer, lower-loft fill.
Memory foam is the strongest match for side sleepers who want steady neck and spine support:
- Solid memory foam holds a fixed shape and returns to form after pressure is removed.
- Shredded memory foam offers the same support but lets you add or remove fill to adjust the loft.
Down alternative and cotton fills suit sleepers who prioritize breathability or hypoallergenic comfort:
- Down alternative gives a soft, cloud-like feel without feather allergens.
- Cotton fill breathes well and suits warmer sleepers or hot rooms.
- Feather fill offers a more traditional, firmer feel for sleepers who like extra resistance.
Best Pillow for Back, Stomach, and Combination Sleepers
-
Back sleepers generally do best with a medium-loft pillow that supports the natural curve of the neck without pushing the head too far forward. Down alternative or a softer shredded memory foam both work well here.
-
Stomach sleepers need the lowest loft of any sleep position, since a thick pillow tilts the neck at an angle all night. A thin cotton or down alternative pillow is usually the safer choice.
-
Combination sleepers, who shift positions through the night, tend to do best with an adjustable fill like shredded memory foam, since you can add or remove material to suit whichever position you land in.
Firm vs Medium vs Soft Pillow, and Loft by Sleep Position
Firmness and loft (the pillow's height when uncompressed) work together to determine support:
| Sleep Position |
Recommended Loft |
Recommended Firmness |
| Side |
High loft |

If you're unsure where you land, our choose perfect sleep pillow guide walks through matching fill and loft to your specific sleep habits, and our best pillow by position guide breaks it down position by position.
Best Pillow for Neck Support, Hot Sleepers, Kids, Pregnancy, and Allergies
-
Neck support: Firmer memory foam, especially contoured or shredded fill, gives the most consistent support for keeping the spine aligned.
-
Hot sleepers: Cotton or bamboo covers paired with a breathable fill like down alternative help avoid overheating.
-
Kids: Lower-loft, lightweight pillows with hypoallergenic fill and a machine-washable cover are the easiest to keep clean and safely sized for smaller frames.
-
Pregnancy: A full-length body pillow generally offers more consistent support than a standard pillow; see our pregnancy body pillow benefits guide for specifics.
-
Allergies: Hypoallergenic fill paired with a certified allergen-barrier protector, covered in more detail below.
Down vs Down Alternative vs Memory Foam vs Latex
-
Down is a natural fill known for being soft and lightweight, but it can trigger allergies in sensitive sleepers and generally needs more careful cleaning.
-
Down alternative mimics that soft, cloud-like feel using synthetic fibres, without the allergen risk, though it typically compresses faster over time than down or foam.
-
Memory foam holds a firmer, more consistent shape and contours to the head and neck, making it the strongest choice for support, though it doesn't breathe quite as well as natural fills.
-
Latex offers a springier, more responsive feel than memory foam with similar durability, and tends to sleep cooler, but it's typically the more expensive option and isn't suitable for people with latex sensitivities. Our organic latex body pillow benefits guide covers this fill type in more depth.
What's the Difference Between Bamboo, Silk, and Satin Covers?
Bamboo, silk, and satin covers can all feel cooler and lower-friction than standard cotton, but each achieves it differently and at a different price point. Bamboo-derived fabric is generally more moisture-wicking than plain cotton, though the exact cooling effect depends on the specific weave and blend rather than being guaranteed across every bamboo product. Silk minimizes friction on skin and hair, and satin offers a similar low-friction feel to silk at a more accessible price. For more on how your cover choice affects your rest, read our bedcovers improve sleep quality guide.
| Cover Fabric |
Best For |
Key Benefit |
| Cotton |
Everyday use, hot sleepers |
Breathable, easy to wash |
| Bamboo |
Summer months, overheating sleepers |
Generally moisture-wicking, cooling surface |
| Silk |
Skin and hair care |
Lowest friction, premium feel |
| Satin |

Bamboo vs Silk Pillowcase, and Satin vs Cotton Pillowcase
Bamboo tends to win on moisture control and breathability, while silk wins on the lowest overall friction against skin and hair, so the choice often comes down to whether you run hot at night (bamboo) or prioritize skin and hair care (silk). Satin, meanwhile, gives you much of silk's smooth, low-friction surface at a price closer to cotton, while cotton remains the most breathable, easiest-care, and most affordable everyday option. For a full side-by-side, see our silk vs satin pillowcase guide.
What Pillow Size Do You Actually Need?
Choosing the correct pillow size prevents the compressing, sliding, and uneven support that happens when a pillow doesn't match your bed or sleep position. Canadian pillow sizing generally follows a few standard dimensions, regardless of brand. For a full breakdown of mattress and bedding dimensions, see our Bed Sizes guide.
| Size |
Approximate Dimensions |
Best For |
| Standard |
51 x 66 cm (20" x 26") |
Single, double, and most queen beds |
| Queen |
51 x 76 cm (20" x 30") |
Queen mattresses needing extra length |
| King |
51 x 92 cm (20" x 36") |
King beds; commonly sold as a 2-pack |
| Body Pillow |
51 x 137 cm+ |
Side-sleeper support, pregnancy, recovery |
| Kids |
Approx. 40 x 60 cm |
Children's beds |
Standard and queen pillows fit most adult beds, but king mattresses are wide enough to need the longer king-size pillow, using standard pillows on a king bed usually leaves visible gaps.
Pillow Sizes by Bed Size: Twin, Full, Queen, King
-
Twin and Twin XL: Typically dressed with one or two Standard pillows.
-
Full: Two Standard pillows is the common setup.
-
Queen: Two Standard or Queen pillows, with Queen giving slightly more width coverage.
-
King and California King: Two King-size pillows are the standard fit; using Queen or Standard pillows here tends to look undersized against the width of the bed.
If you're outfitting a dorm room specifically, our dorm bedding buying guide covers Twin XL-specific sizing in more detail.
Pillowcase Sizing: Does It Come with the Pillow, and Which Case Fits Which Pillow?
Pillows and pillowcases are sold to matching size standards (Standard, Queen, King), but pillowcases don't always come bundled automatically. Some pillow-and-case sets include a matched cover, while single pillows are often sold insert-only, so check the listing before assuming a case is included.
Can you use a Queen pillowcase on a Standard pillow? Yes, generally. A Queen case is a bit larger than a Standard insert, so it will fit but with a slightly looser, less filled-out look.
Can you use a King pillowcase on a Queen pillow? Yes, with the same trade-off: it fits, but the extra length means the case won't be fully filled out, and the insert can shift more inside the case.
Going the other direction (a smaller case on a larger insert) is not recommended, since the case will strain at the seams and wear out faster. For a full compatibility chart across all four sizes, see our pillowcase size guide.
Which Pillows Work Best for Sensitive Sleepers?
Sensitive sleepers, including those with dust mite allergies, eczema, or asthma, benefit most from a hypoallergenic fill paired with a certified allergen-barrier cover. This combination helps reduce exposure to common triggers without introducing the crinkling texture some barrier fabrics have.
Hypoallergenic pillows are formulated to reduce common allergy triggers and typically avoid feathers and added fragrances, though "hypoallergenic" is a general claim rather than a guarantee that every specific allergen is absent, so anyone with a diagnosed sensitivity should check the specific materials listed on a given product. This makes hypoallergenic options a common recommendation for children's rooms as well as adult bedrooms with allergy concerns. Pairing them with a protective layer can help too; see our guide on extending mattress lifespan waterproof protectors for more on layering protection into your setup.
Should You Buy a Single Pillow or a Pillow Set?
A single pillow with case is the right call when you're only replacing one worn-out pillow, while a set makes more sense when you're outfitting an entire bed, bedroom, or guest room at once. Sets typically include matched covers across two or more pillows, which keeps the look and feel consistent. If you're shopping for a dorm room specifically, you can learn more in our dorm bedding buying guide.
- Buy a single pillow if: you're replacing one pillow and keeping the rest of your setup as is.
- Buy a set (often 2-pack) if: you're setting up a new bed, a guest room, or want every pillow on the bed to match.
How Many Pillows Do You Need on a Bed?
Most adults use two sleeping pillows per person as a baseline, with couples typically needing four for a shared bed. Add one or two decorative Euro shams behind the sleeping pillows if you want a more layered, hotel-style look. Guest rooms are usually fine with two pillows per expected sleeper, plus a spare in the closet for preference differences.
Caring for Pillows and Pillowcases
Keeping both the insert and the cover clean matters for hygiene as much as appearance, and different fill types and fabrics need different handling.
How to Wash a Pillow by Fill Type
-
Memory foam: Never fully submerge or machine wash a solid memory foam pillow, since it holds water and can break down. Spot clean the surface with a damp cloth and mild detergent, then air dry completely before use. Shredded memory foam pillows with a removable liner can sometimes be hand washed; check the care label first.
-
Down and down alternative: Machine washable on a gentle, cold cycle in most cases, but pillows need to be fully dried, often requiring multiple dryer cycles on low heat with dryer balls to prevent clumping.
-
Cotton and feather: Generally machine washable on a gentle cycle; feather pillows benefit from an extra rinse cycle to fully clear detergent from the fill.
-
Body pillows: Follow the same fill-based rules above; our how to wash a body pillow guide covers the full-length format specifically.
How to Wash a Pillowcase and Specialty Covers
Cotton and polyester-blend pillowcases are typically machine washable on a normal cycle. Bamboo pillowcases generally prefer a gentle, cold cycle to preserve the fibre's softness; see our how to wash bamboo pillow guide for fabric-specific detail. Silk and satin covers need cold water and a gentle or hand-wash cycle, since heat and agitation degrade both fabrics quickly.
How to Keep Pillows Hygienic Between Washes
A removable, washable pillowcase paired with a zippered protector underneath is the most effective way to extend the time between full pillow washes, since most of the sweat, oil, and skin contact never reaches the insert itself.
How Often Should You Replace a Pillow?
Most pillows lose shape and support over time regardless of fill type, so checking for flattening, lumping, or reduced loft periodically is more reliable than following a fixed replacement schedule.
-
Memory foam: Generally holds its shape the longest, often 2 to 3 years or more before noticeable breakdown.
-
Down and down alternative: Tends to compress faster, often needing replacement or refluffing attention within 1 to 2 years.
-
Feather and cotton: Similar timeline to down, typically 1 to 2 years depending on use.
A pillow with a removable, washable cover is easier to keep hygienic between replacements, regardless of fill type.
Frequently Asked Questions
What is a pillow with a case, and why buy them together?
A pillow with a case is a bed pillow sold together with a matching protective or decorative cover, so the fill and fabric are sized and paired correctly from the start. Buying them together avoids the fit and hygiene issues that come from mismatching an old case with a new pillow.
Which pillow fill is best for side sleepers?
Memory foam, especially shredded memory foam, is generally the best match for side sleepers, since it holds firm, adjustable support under the head and neck through the night.
Are bamboo pillow covers actually cooler than cotton?
Generally, yes. Bamboo-derived fabric tends to wick moisture and dissipate heat faster than standard cotton or polyester, which is why it's commonly recommended for hot sleepers and warmer months, though the exact effect varies by weave and blend rather than being identical across every bamboo product.
Are hypoallergenic pillows safe for kids?
Generally, yes. Hypoallergenic pillows combine allergen-reducing covers with fills formulated to avoid feathers and added fragrances, making them a common choice for children's rooms, especially where eczema, asthma, or dust sensitivity is a concern, though anyone with a diagnosed allergy should confirm the specific materials used.
What size pillow should I buy for a king bed?
King-size pillows (approximately 51 x 92 cm, or 20" x 36") are built for the width of a king mattress and are usually sold in pairs. Using standard-size pillows on a king bed typically leaves noticeable gaps.
What's the difference between silk and satin pillow covers?
Silk is a natural fiber that offers the lowest friction against skin and hair, while satin is typically a woven synthetic or blended fabric that mimics silk's low-friction feel at a lower price point.
How often should I replace a pillow?
Most pillows lose shape and support over time regardless of fill type, so checking for flattening, lumping, or reduced loft periodically is more reliable than following a fixed replacement schedule. A pillow with a removable, washable cover is easier to keep hygienic between replacements.
Do pillows come with a matching pillowcase included?
Not always. Some pillow-and-case sets are bundled together, but many pillows are sold as the insert only, so it's worth checking the product listing before assuming a case is included.
Can you use a pillowcase from a different size pillow?
Sizing up works in a pinch (a Queen case on a Standard pillow, or a King case on a Queen pillow), though the fit will be looser. Sizing down is not recommended, since the case will stretch at the seams and wear out faster.
