Buyer's Guide to Bedding

Discover how to choose the perfect duvet, pillow, and bedding for every season with Feather & Black’s expert guide.

Good bedding is the foundation of a restful night’s sleep, and at Feather & Black, we believe it should feel as exquisite as it looks. Our experts have created this guide to help you design the perfect sleep sanctuary, bringing together everything from a detailed bedding size chart to a pillowcase size chart for a flawless fit.

Discover the ideal bedding size for every bed and the perfect pillowcase proportions to complete your space, while exploring fabrics and finishes that combine timeless elegance with exceptional comfort.

The start of a perfect night’s sleep begins with the bed sheets

Well-fitted sheets create the ideal foundation for your duvet and pillows, enhancing the appearance of your bed with an elegant drape and supporting a more restful night’s sleep. Ill-fitting sheets can bunch, slip, or look untidy, disrupting comfort and style.

Measure your mattress and use our bedding size chart to match the dimensions, for a perfect fit that’s as practical as it is beautiful.

Bed Sheet Size	Dimensions (W X L)
Single bedding size	135cm x 200cm
Double bedding size	200cm x 200cm
King-size bedding	230cm x 220cm
Super king-size bedding	260cm x 220cm
Emperor-size bedding	290cm x 235cm

How the fabric and fit can transform a bed sheet

Every detail of your bed sheets contributes to the elegance and comfort of your sleep space. The right bedding size ensures a beautifully smooth surface, whilst the fabric choice elevates your sleeping experience and is just as important as the fit.

Cotton bed sheets provide crisp, breathable comfort that suits every season, while Egyptian cotton bed linen offers an elevated softness with its renowned, silky fibres. For a more relaxed yet sophisticated aesthetic, a linen bedding set introduces natural texture and cooling freshness.

200–300 thread count bedding provides lightness and airflow, ideal for summer nights or warmer sleepers.
300–500 delivers a perfect blend of softness and strength, suited for year-round use.
600 and above creates a dense, smooth weave, perfect for those seeking a cocooning, indulgent feel.

While thread count can guide your choice, the calibre of the weave defines true luxury. For more insight, explore our guide on what a good thread count for bedding is.

How to choose a duvet size that complements your bed

A well-chosen duvet does more than provide warmth. The right size and tog rating elevate the comfort and appearance of your bed, ensuring you sleep soundly, and wake refreshed throughout every season.

Duvet Size	Dimensions (W x L)
Single	135cm x 200cm
Double	200cm x 200cm
King	230cm x 220cm
Super King	260cm x 220cm
Emperor	290cm x 235cm

For a cocooning feel, our experts recommend sizing up - pairing a super king-size bedding set with a king mattress, for instance. The generous overhang adds visual depth and a sense of indulgence and envelops you in unmatched warmth during the colder months.

What is the best duvet filling?

A duvet’s filling lies at the heart of its comfort. It shapes how the duvet feels and how it performs night after night. From its weight and warmth to its breathability, the filling defines your sleep experience. Each type offers its own benefits, but the best choice always comes down to what feels right for you.

Natural duvets

Our natural duvets are filled with the finest feathers and down and encased in a 100% cotton cambric cover. They’re super soft, luxurious and insulating, allowing your skin to breathe whilst keeping you beautifully snug.

Down-filled duvets

Down is found on the belly of a bird and lies beneath the protective layer of outer feathers. It’s light, fluffy, soft and airy and is by far the most prized and best-performing duvet filling.

Our down-filled duvets are lofty, lightweight, and offer the best level of warmth due to the superior insulating properties of down and keep you at just the right temperature.

Feather-filled duvets

Feather-filled duvets are known for their reassuring weight and lasting support. The larger, more robust feathers create a plump, cocooning duvet that offers a comforting sense of substance while retaining natural breathability. Perfect for those who enjoy the feel of a duvet with a little more weight, this filling delivers durability and warmth, wrapping you in comfort night after night.

Feather & down-filled duvets

Feather and down-filled duvets offer the perfect balance of weight, warmth and comfort. The down provides exceptional insulation, gently trapping heat to keep you at the ideal temperature through the night, while the feathers add structure and durability for a cocooning feel with reassuring substance.

Pillows and pillowcases sizes for crafted comfort

The right pillow does more than enhance the appearance of your bed; it plays a crucial role in supporting your head, neck, and shoulders during sleep. We believe that comfort and style should go hand in hand, which is why our pillows are thoughtfully designed to cater to a variety of sleep styles and preferences.

How are our pillows sized?

Our pillows are available in a range of sizes to suit your sleeping style and the look of your bed. Each of our pillowcases is thoughtfully designed to deliver the perfect blend of comfort, support and elegance.

Pillow Size	Dimensions (W x L)
Oxford / Standard	50cm x 75cm
Super King	50cm x 90cm

Finding the perfect pillow

The ideal pillow gently supports your natural posture, enhancing comfort and helping you sleep deeply through the night. The right choice depends on how you rest:

Back sleepers find comfort in a single, soft pillow that provides subtle support without raising the head too high.
Side sleepers benefit from a firmer, loftier pillow that keeps the head, neck, and spine aligned.
Front sleepers should rest on a soft, low-profile pillow that reduces strain and allows the head to settle comfortably.
All-sides sleepers often prefer layering a soft pillow over a firmer one, offering adaptable support as they change position.

The craftsmanship behind pillow fillings

The filling defines the feel, support, and lasting comfort of your pillow. Each option brings its own unique qualities, allowing you to choose what suits your sleep style best.

The gentle loft of feather and down pillows

Natural pillows are filled with a carefully balanced blend of feather and down. This creates a soft, breathable loft that gently supports while offering a sense of lightness. Every natural pillow is encased in a cotton cover for added softness and fresh, airy comfort.

Anti-allergy pillows for a peaceful sleep

Anti-allergy pillows are thoughtfully crafted with synthetic, non-allergenic fibres encased in a soft polyester cover. Filled with Sensifil polyester fibres, they are recognised as asthma and allergy-friendly, offering peace of mind for sensitive sleepers. Fully machine washable, they provide practical comfort without compromising on quality.

Consistent support with natural latex comfort

Latex pillows are crafted from natural latex and provide firm, responsive support that keeps their shape night after night. Naturally breathable and hypoallergenic, they are ideal for side and back sleepers seeking consistent, long-lasting comfort.

Toppers and protectors: The finishing touch for comfort and care

A mattress topper is an effortless way to enhance the feel of your bed, adding a soft, luxurious layer without the need to replace your mattress. Designed to fit all standard mattress sizes, our mattress toppers are secured with elasticated corner straps to keep them in place throughout the night. Choose from natural fillings, with a harmonious blend of feather and down for sumptuous comfort, or hypoallergenic options made from antibacterial fibres that are fully machine washable.

Pillow and mattress protectors are also a simple yet essential way to prolong the life of your bedding and keep your sleep space fresh and hygienic. For expert advice on choosing the best mattress topper for your sleep style, discover our guide.

When to refresh your bedding for lasting comfort and support

Refreshing your bedding at the right time is key to preserving both comfort and the quality of your sleep. We recommend replacing your duvet every five to ten years to ensure it continues to provide the warmth, softness and support you expect. If your duvet appears discoloured, develops cold spots, feels lumpy, or if an anti-allergy filling begins to trigger allergy symptoms, it’s time to consider a replacement.

Pillows are just as important. They provide essential support for your head and neck, and should typically be replaced every two to four years to maintain proper alignment and comfort. If your pillow droops when placed over your arm, looks discoloured, feels lumpy or flat, or causes neck ache or allergy flare-ups, it may no longer be offering the support you need.
