Building a Better Bed Starts with the Basics
Duvet sets often get all the attention, but the sheets and pillowcases underneath are just as important. A well-fitted sheet keeps your mattress protected and comfortable. The right flat sheet adds a layer of warmth. And quality pillowcases can make or break a good night's rest.
This guide covers everything you need to know about choosing fitted sheets, flat sheets and pillowcases — from materials and sizing to practical care tips.
Fitted Sheets: The Foundation of Comfort
What Makes a Good Fitted Sheet
A good fitted sheet stays put. It should have deep enough pockets to wrap securely around your mattress without pinging off at the corners during the night. The fabric should feel comfortable against your skin and be durable enough to withstand regular washing.
At Kumperi, the Lyla King Fitted Sheet in Olive is a popular choice. It offers a snug fit and a soft finish that works well with coordinating duvet sets and throws.
Choosing the Right Size
Fitted sheet sizes correspond to standard UK mattress dimensions
Single: 90 x 190 cm
Double: 135 x 190 cm
King: 150 x 200 cm
Super King: 180 x 200 cm
Always check the depth of your mattress. If you have a deep mattress or mattress topper, you will need a fitted sheet with deeper pockets. Standard depth is around 25 cm, but some mattresses require 30 cm or more.
The Lyla Double Fitted Sheet in Olive and the Lyla Fitted Sheet in Stone offer options for different bed sizes in coordinating colours.
Material Options
Percale weave sheets are crisp and cool, making them ideal for warmer months. Polycotton blends offer durability with less ironing required. The Lyla King Fitted Sheet in Black is another excellent option for those who prefer darker bedding that hides wear and tear.
Flat Sheets: An Often Overlooked Essential
Why Use a Flat Sheet
Flat sheets sit between you and your duvet, creating an extra layer that protects your duvet cover from body oils and sweat. This means you can wash your duvet cover less frequently, extending its lifespan. In warmer months, a flat sheet on its own can replace a duvet entirely.
Choosing and Using Flat Sheets
The Percale Flat Sheet in White available. Kumperi is a classic choice. Percale fabric has a smooth, matte finish and a cool feel — perfect for those who sleep warm. White flat sheets are versatile and coordinate with any duvet set colour.
When buying a flat sheet, choose one size larger than your bed for a generous tuck. A king-size flat sheet on a double bed, for instance, gives you plenty of fabric to tuck neatly under the mattress.
Pillowcases: Small Details, Big Impact
Standard Housewife Pillowcases
Housewife pillowcases are the most common style in the UK. They have a simple envelope closure that tucks the pillow inside without any visible fastenings. The Percale Housewife Pillowcase Pair in White from Kumperi is a staple — crisp, clean and suitable for everyday use.
V-Shaped Pillowcases
V-shaped pillowcases are designed for orthopaedic or nursing pillows. They provide support for reading in bed, watching television or for those recovering from surgery. The Percale V-Shape Orthopaedic Pillowcase in White fits standard V-shaped pillows and is made from breathable percale fabric.
Matching Your Pillowcases
Many Kumperi duvet sets include matching pillowcases, but you can also buy additional pairs separately. The Lyla Pillowcase Pair coordinates beautifully with the Lyla fitted sheet and duvet ranges, making it easy to create a polished, cohesive look.
Caring for Sheets and Pillowcases
Washing Frequency
Fitted sheets and pillowcases should be washed weekly. Flat sheets can be washed every one to two weeks. Regular washing removes dust mites, dead skin cells and oils that accumulate over time.
Washing Tips
Wash at 40°C for everyday cleaning.
Use a 60°C wash occasionally to kill dust mites, particularly if anyone in the household has allergies.
Avoid using fabric softener on percale sheets, as it can reduce breathability.
Wash dark and light colours separately to prevent colour transfer.
Drying and Storage
Line drying gives the freshest finish, but tumble drying on low heat works well too. Fold sheets promptly after drying to minimise creasing. Store in a linen cupboard with good airflow.
How to Style Your Bed Like a Professional
The Layered Look
Start with a fitted sheet, add a flat sheet, then your duvet. Fold the flat sheet over the top edge of the duvet for a crisp finish. Add two or three extra cushions in front of your sleeping pillows for depth and visual interest.
Colour Coordination
Keep your sheets and pillowcases in a neutral palette — whites, creams and soft greys — and let your duvet set provide the colour and pattern. This approach makes it easy to switch out your duvet set seasonally without replacing all your bedding.
The Hotel Tuck
For a polished look, tuck your flat sheet tightly under the mattress using hospital corners. This technique keeps the sheet smooth and wrinkle-free throughout the night.
Protecting Your Mattress
While not a sheet in the traditional sense, a mattress protector is worth mentioning. The Waterproof Quilted Mattress Protector sits beneath your fitted sheet and guards against spills, stains and allergens. It is a small investment that extends the life of your mattress considerably.

Final Thoughts on Building Your Bedding Collection
Buying sheets and pillowcases does not need to be complicated. Start with two sets of fitted sheets, so you always have a clean one ready while the other is in the wash. Add a flat sheet if you want that extra protective layer, and keep a few spare pillowcase pairs on hand for quick refreshes between full bedding changes.
By investing in well-made basics that coordinate with your duvet sets, you create a bedroom that feels complete, comfortable and easy to maintain throughout the year.
