A little more room for your nightly silk moment. Our Super King silk pillowcases fit 50 × 90 cm pillows, in substantial 25 Momme Mulberry silk with our much-loved soft-touch matte finish. Choose a quiet colour or a print with personality. Your side of the bed, your rules.
There is something rather inviting about a long pillow dressed in silk. Room to settle in, turn over and find that smooth, cool first touch again. Our Super King silk pillowcases fit pillows measuring 50 × 90 cm, with the same soft-touch matte finish our community of silk sleepers loves.
Each is made from 100% Grade 6A long-fibre Mulberry silk in 25 Momme, individually hand-cut and machine-stitched. Supple against your cheek, quietly beautiful on the bed and far too nice to save for guests.
Choose Classic for a clean outline or Oxford for a framed finish, in the colours and prints available in this size. The product grid above shows Super King variant prices and takes you straight to that size.
Momme measures silk fabric weight, rather than thread count. Our 25 Momme silk has a substantial, supple feel: cloth with a little body, a soft fall and that easy glide against your cheek. The number has a purpose. You should be able to feel it.
Each pillowcase is made from 100% Grade 6A long-fibre Mulberry silk, individually hand-cut and machine-stitched. Mulberry silk comes from silkworms fed Mulberry leaves. Fibre, weave and finishing all matter, which is why we pay attention to the whole cloth.
Then comes our signature soft-touch matte finish. A restrained lustre, rather than a glossy surface. It gives plain colours depth and prints definition, while feeling wonderfully inviting. This is silk made to live with, as much as to look at.
For the details, explore our Momme guide and silk grades.
Silk's smooth surface means less friction, catching and pulling as you turn your head. For curly hair, fine hair or a carefully styled blow-dry, that gentle glide can mean fewer tangles and less friction-related frizz. If frizzy hair is your morning complaint, your pillow is a good place to start. Your hair has enough to contend with during the day.
Smooth silk can help minimise temporary sleep creases and feels gentle against sensitive skin. It also absorbs less moisture than cotton pillowcases, helping preserve your skin's natural moisture. For dry skin, that lower absorbency and soft contact make a lovely companion to your evening skincare routine.
Naturally breathable and thermoregulating silk helps support a comfortable sleep environment. Enjoy its cool first touch and the way it moves with you. A softer place to settle into, whether the window is open or the duvet is firmly tucked in.
You do not need to replace the whole bed. A single pure silk pillowcase brings the difference to the place you feel it most. A pair makes your existing bed linen feel newly dressed. Start small. See how attached you become.
Keep it tonal with Ivory, Brilliant White or Oyster Grey. Add a little warmth with Precious Pink, or depth with Midnight Blue and Charcoal. Let a designer print be the focal point, a botanical detail, a flash of feathers or something rather less shy.
Our printed silk pillowcases use the same 25 Momme pure Mulberry silk as the plain colours. Choose the design that makes you smile. The cloth is every bit as lovely underneath.
For a clean outline, choose Classic. For a little more framing, choose an Oxford border. A pair need not match, either. It is your bedroom, after all.
Build on the feeling with silk sheets and duvet covers, or enjoy your pillowcases with the cotton and linen pieces you already love.
These pillowcases fit 50 × 90 cm pillows, labelled UK Super King / US King in our range. Measure the pillow itself: a king-size mattress does not necessarily mean you have a Super King pillow.
Oxford styles add a 3 cm decorative border beyond the pillow fit. Both Classic and Oxford use an envelope closure, with no zip against your cheek.
For 50 × 75 cm pillows, explore our Standard pillowcases. Check the pillowcase size chart before ordering.
Mayfairsilk pillowcases can be machine washed on a silk or delicate cycle, or gently hand washed. Turn inside out, use a mesh laundry bag and select cold water or a setting below 30°C, with a pH-neutral, enzyme-free detergent suitable for silk.
Skip bleach and fabric softener. Press out water gently, without wringing, then air dry in the shade. Do not tumble dry. A little care keeps this an everyday pleasure.
Wash pillowcases weekly as a starting point, sooner when needed. Our silk care guide takes you through the full washing process.
The best way to understand the feel of our silk is to sleep on it. Feel the difference with our 30-night sleep guarantee. Try your pillowcase at home and, if it is not right for you, contact us to arrange a return for a refund of the pillowcase purchase price.
For non-faulty returns, return shipping to our UK warehouse is your responsibility. See the full guarantee and returns terms.
Silk is a natural fibre; satin describes a weave. Satin pillowcases may be made from silk, polyester or another fibre. Many use synthetic fabrics, so check composition rather than relying on a silky appearance. Mayfairsilk pillowcases are made from 100% Mulberry silk: real silk, with our soft-touch matte finish. Read our silk versus satin guide.
If the feeling of your bed matters to you, a pillowcase is an accessible way to experience pure silk. You get the smooth surface for skin and hair without replacing all your bedding. Compare composition, Momme weight, finish, fit and care, then use our 30-night sleep guarantee to discover whether Mayfairsilk is right for you, subject to the linked terms.
At the same fabric dimensions, 25 Momme contains about 14% more silk by weight than 22 Momme and about 32% more than 19 Momme. That gives the cloth extra substance, but weight is only part of quality. Grade, weave, finish and construction matter too. Our pillowcases combine 25 Momme Grade 6A Mulberry silk with a soft-touch matte finish.
Silk's smooth surface helps reduce friction, tugging and tangling as you move in bed. That can help minimise morning bedhead and friction-related frizz, whether your hair is curly, fine, straight or styled. The hair benefits come from a gentler glide, alongside the haircare routine that suits you.
Smooth silk can help minimise temporary sleep creases and feel gentle against sensitive skin. It absorbs less moisture than cotton, helping skin retain more of its natural moisture. Choose it for comfort and smooth contact as part of your routine.
Silk is naturally breathable and thermoregulating, with a cool first touch that hot sleepers may enjoy. Your pillow filling, duvet, room temperature and personal preference also influence overnight comfort. Choose the layers around you for the season.
Our Super King pillowcases fit pillows measuring 50 × 90 cm. This is our UK Super King / US King size. An Oxford border adds 3 cm of decorative fabric around that fit; it does not change the pillow size. Measure your pillow and check our size chart before ordering.
No. Both Classic and Oxford pillowcases use an envelope closure to keep the pillow neatly tucked inside. No zip to press against your cheek. Ease the pillow into place and tuck it into the pocket rather than pulling hard on the silk.
Classic has a clean outline without an Oxford flange; some designs have fine piping. Oxford adds a 3 cm decorative border to frame the pillow. Both use the same 25 Momme silk and an envelope closure. Choose the look you prefer and check available sizes on the product page.
Yes. Our designer prints use the same 25 Momme pure Mulberry silk and soft-touch matte finish as the plain-colour range. Colour and pattern change the look, not the fabric weight. Not every print is offered in both sizes, so check your chosen design.
Yes, following the product label and our care guide. Choose a silk or delicate cycle below 30°C, a mesh laundry bag and a pH-neutral, enzyme-free silk-safe detergent. Wash separately from other fabrics, avoid bleach and fabric softener, then air dry in the shade. Do not tumble dry.
