What size bed sheets do I need?

Measure the width of your mattress to confirm your bed size: 90cm is single, 120cm is small double (4ft), 135cm is double, 150cm is king, 180cm is super king. For fitted sheets, also measure the total depth of your mattress including any topper or protector - this determines whether you need a standard 30cm, extra deep 38cm, or ultra deep 46cm sheet. Belledorm also stocks specialist sizes including bunk bed, long single, IKEA Euro king, emperor, and large emperor.

What is the best fabric for bed sheets?

The best fabric depends on how you sleep. Polycotton (200 thread count) is lightweight, crease-resistant, and quick to dry - practical for everyday use. Cotton sateen at 300 or 600 thread count feels smoother and has a slight sheen. Egyptian cotton uses longer-staple fibres for a more consistent surface that softens with washing and resists pilling. Bamboo is naturally moisture-wicking and suits warm sleepers. Brushed cotton flannelette traps warmth for winter. Jersey cotton has a stretchy, T-shirt-soft feel.

What is the difference between a fitted sheet and a flat sheet?

A fitted sheet wraps around the mattress and is held in place by elasticated corners. It stays put overnight and is the standard base layer for most beds. A flat sheet is a single, unhemmed piece of fabric that sits between you and the duvet. It adds a layer of temperature regulation, protects the duvet cover from body oils and perspiration, and gives the bed a traditional, hotel-style finish. Many people use both together; some prefer just a fitted sheet and duvet.

How do I stop my fitted sheet from coming off the mattress?

The most common reason a fitted sheet pulls free is that the depth is wrong for the mattress. Measure the total depth of your mattress including any topper and choose a sheet with a box depth that matches - a 30cm sheet on a 28cm mattress will have very little fabric to tuck under and will slip off. Belledorm fitted sheets have fully elasticated edges (not just corner elastic), which keeps the sheet anchored more securely around all four sides of the mattress.

What thread count should I choose for bed sheets?

Thread count measures the number of threads woven into one square inch of fabric. A 200 thread count polycotton or cotton percale has a crisp, cool feel suited to warm sleepers and everyday use. A 400 thread count cotton sateen is noticeably smoother. At 600 thread count and above, the fabric becomes denser and silkier, with a heavier drape. Above 1000 thread count, returns diminish - the weave type and fibre quality matter more than the number itself. Belledorm offers sheets from 200 to 1500 thread count across multiple fabric types.

How often should I wash my bed sheets?

Most sleep hygiene guidance recommends washing sheets every one to two weeks. During warmer months or if you perspire more at night, weekly washing is better for freshness and skin comfort. Belledorm cotton and polycotton sheets can be machine washed at 40°C on a standard cycle. Egyptian cotton and higher thread count sheets benefit from being removed from the dryer slightly damp and smoothed flat to reduce creasing.

Can I buy matching sheets, duvet covers, and pillowcases?

Yes. Belledorm's sheet fabrics are available in matching duvet covers and pillowcases across most ranges, in the same thread count and colourway. This makes it straightforward to coordinate your entire bed from one fabric family. Bedding bundles are also available, which bring together a fitted sheet, duvet cover, and pillowcases in one order with a saving built in.

Do Cotton Sateen sheets get softer after washing?

Cotton fibres have a tendency to soften with each wash. The fibres relax when laundered resulting in a softer finish.

Is Cotton Sateen slippery?

Although a sateen is smooth and silky it is not considered as slippery as other synthetic fibres or silk.

Is 600 thread count Cotton Sateen good?

In short, Yes! It is a beautiful fabric with a tight weave of 600 threads per square inch. Made with long staple yarn, it is durable, breathable and still lightweight. You won't be disappointed.

What are the pros of Cotton Sateen?

Our Cotton Sateen has a smooth and silk feel against the skin. The satin weave gives a subtle sheen enhancing its visual appeal.

Finding the right bed sheet

The type of sheet you need depends on your bed, your mattress depth, and how you prefer your bedding to feel. Fitted sheets sit over the mattress and are held in place by elasticated corners - Belledorm fitted sheets are available in three depths: standard 30cm for mattresses up to 22cm, extra deep 38cm for mattresses up to 30cm including those with a topper, and ultra deep 46cm for the deepest mattresses and adjustable beds. Flat sheets sit between you and the duvet and are the traditional choice for a layered, hotel-style bed.

Fabric makes the biggest difference to how a sheet feels. 200 thread count polycotton is lightweight, crease-resistant, and quick to dry - ideal for everyday use and children's beds. Egyptian cotton uses longer-staple fibres that produce a smoother, more consistent surface, and is available from 200 to 1200 thread count. For cooler sleep, bamboo has natural moisture-wicking properties. In winter, brushed cotton flannelette traps warmth with its soft, napped finish.

All Belledorm sheet fabrics are available in matching duvet covers and pillowcases, so you can coordinate your whole bed in one thread count and colourway
