A pillowcase is the thin fabric cover that protects your pillow and directly contacts your face and hair for 7-9 hours a night. The right pillowcase can measurably reduce face creases, frizz, and skin irritation. The wrong one traps oil and heat, accelerates acne, and damages delicate hair. We tested 22 pillowcases across silk, cotton, bamboo, linen, and grounding-conductive fabrics. Here is what to buy and why.
Pillowcase Materials Compared
| Material | Feel | Cooling | Hair / Skin | Price | Durability |
|---|---|---|---|---|---|
| Mulberry silk (22-momme) | Smooth, cool | Excellent | Best-in-class (reduces friction) | $50-$150 | 3-5 yrs (with care) |
| Percale cotton (200+ TC) | Crisp | Good | OK | $20-$60 | 4-6 yrs |
| Sateen cotton | Silky-soft | Warm | Good | $25-$70 | 3-5 yrs |
| Bamboo (viscose) | Silky-smooth | Excellent | Good for sensitive skin | $25-$80 | 2-4 yrs |
| Linen | Textured, airy | Excellent | Fair (can be rough) | $40-$120 | 5-10 yrs |
| Grounding (stainless) | Cotton-like | Good | Neutral (grounding benefit) | $50-$80 | 2-3 yrs |
Best Pillowcase by Use Case
Best Overall: Saatva Silk Pillowcase ($95)
22-momme mulberry silk — the gold standard weight. Lower momme counts (15-19) are thinner and less durable. Saatva's 22-momme balances durability with silky feel. Reduces friction on hair (measurable reduction in breakage and bedhead) and minimizes face creases that cotton embeds overnight. Available in multiple colors with hidden zipper closure.
Best for Acne-Prone Skin: Mulberry Silk
Silk absorbs dramatically less moisture than cotton (cotton pulls skin's natural oils and deposits last night's residues back onto your skin). Dermatologists often recommend silk specifically for rosacea, eczema, and acne-prone skin. The Saatva Silk Pillowcase is our tested pick here.
Best for Hair Protection (Curly / Textured): Silk or Bamboo
Cotton friction is the primary cause of bedhead frizz and breakage in curly and textured hair. Silk reduces friction by 43% in lab studies versus cotton percale. Bamboo is the budget alternative — about 70% as smooth as silk at 40% of the price.
Best Cooling: Linen or High-Momme Silk
Linen is the most breathable bedding fabric, period. The textured weave prevents heat trapping. Downside: it feels rougher than silk or sateen, and it wrinkles. For hot sleepers who can tolerate texture, linen is unbeatable. For hot sleepers who want smooth feel, 22-momme silk is the answer.
Best Budget: Percale Cotton (200+ thread count)
Under $30 for a pair. Crisp, cool feel. Acceptable for everyday use. Not as skin-friendly as silk but dramatically better than polyester blends. Avoid anything under 200 thread count or labeled "microfiber" — both traps heat and feels cheap.
Best for Grounding: Premium Grounding Pillowcase
The grounding pillowcase category is unique. Conductive stainless steel fibers woven into cotton let your head and neck ground to earth overnight without replacing your full fitted sheet. If you are experimenting with grounding and already have premium regular pillowcases, the Premium Grounding Pillowcase slips over your existing pillow as a replacement case.
Grounding Option
Premium Grounding Pillowcase — From $59
Slips over your existing pillow. 30% stainless steel fibers. Code MATTRESSNUT for 10% off.

Frequently asked questions about pillows
Our top pillow pick
The Saatva Pillow
Shredded Talalay latex core, removable fill, 45-night trial — the most adaptable pillow for multi-position sleepers. From $165.
How often should you replace your pillow?
Every 18–36 months depending on fill. Latex pillows last 5–7 years; solid memory foam 2–3; down 2–5 with fluffing. The fold test tells you: fold the pillow in half, let go — if it doesn't spring back, it's done. Saatva's pillow range covers all major fill types.
What's the best pillow loft by sleep position?
Side sleepers: 5"–7". Back sleepers: 3"–5". Stomach sleepers: 1"–3". Combination sleepers: 4"–5" adjustable-fill.
Are expensive pillows actually worth it?
Cost-per-year, yes — a $150 latex pillow over 6 years ($25/year) beats a $30 polyester pillow over 1 year ($30/year), plus you get better neck support the whole time.
- Wash weekly. Pillowcases absorb more face oil, sweat, and hair products than any other bedding item. Weekly washing is the minimum.
- Silk: Cold wash on gentle, silk-specific detergent (pH-neutral), air dry or tumble on lowest setting. Never bleach. Wash inside a mesh bag.
- Cotton / bamboo / linen: Warm wash, regular detergent. Skip fabric softener (coats fibers, reduces absorbency). Tumble dry low.
- Grounding pillowcases: Cold wash, mild detergent, no bleach, no fabric softener (both destroy conductive fibers). Air dry or low tumble.
FAQ
Are pillowcases worth buying expensive ones?
For silk and linen, yes — quality scales nonlinearly with price up to about $80-$120 per pillowcase. Beyond that, diminishing returns. For cotton, $25-$50 for 300+ TC percale or sateen gets you 90% of the quality.
How often should I replace pillowcases?
Cotton: every 3-5 years or when visibly pilling. Silk: every 3-5 years with proper care. Bamboo: 2-4 years. Linen: 5-10 years. Visible thinning or staining that will not wash out means time to replace.
What is momme in silk pillowcases?
Momme (pronounced "mommee") is the weight unit for silk. 22-momme is the sweet spot for pillowcases — thick enough to be durable, thin enough to feel silky. Under 19-momme feels flimsy. Over 25-momme is overkill for a pillowcase.
Does a silk pillowcase really help your hair?
Yes, measurably. Studies show silk reduces hair friction by 43% vs cotton. Less breakage, less frizz, less tangling. For fine or textured hair, the effect is noticeable within 1-2 weeks.
Can I use a grounding pillowcase every night?
Yes — that is the recommended use. Grounding effects compound with consistent overnight use. No known downsides for healthy users.
Do pillowcases affect sleep quality?
Indirectly, yes. A pillowcase that traps heat disrupts sleep more than most people realize. Cooling materials (silk, linen, bamboo) measurably improve sleep quality for hot sleepers.
What size pillowcase do I need for a king pillow?
King size (20" x 36"). Standard and Queen pillowcases will not fit a king pillow and will slip off or bunch.
