What types of bed sheet does Belledorm sell?

Belledorm sells fitted sheets, flat sheets, pillowcases, and valance sheets. Fitted sheets have elasticated corners and are available in three depths: standard 30cm, extra deep 38cm for thicker mattresses, and ultra deep 46cm for the deepest mattresses and adjustable beds. Flat sheets sit between you and the duvet for a layered feel. All sheet types are available in fabrics from 200 thread count polycotton through to 1200 thread count Egyptian cotton, plus bamboo, jersey cotton, brushed cotton flannelette, Pima cotton, silk, and linen.

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.

What is a flat sheet and do I actually need one?

A flat sheet is a lightweight rectangular layer that sits between you and your duvet. It adds comfort, helps regulate temperature, and keeps your duvet cover cleaner for longer, meaning you wash it less often. Many customers also use a flat sheet on its own during warmer months as a breathable alternative to a full duvet. It is a simple upgrade that makes a noticeable difference to your sleep routine.

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

A fitted sheet has elasticated corners that wrap securely around your mattress to create a smooth, stable base. A flat sheet lies loosely over the top and can be tucked in for a crisp, hotel-style finish. They work best together - the fitted sheet protects your mattress, the flat sheet adds comfort and reduces how often your duvet cover needs washing. Belledorm offers both in matching collections across the full range.

What size flat sheet do I need?

Choose the size that matches your mattress - Single, Double, King or Super King. Belledorm flat sheets are generously cut to allow for easy tucking on all sides. If you prefer a more dramatic drape or a hotel-style layered look with extra overhang, sizing up is a good option.

Which flat sheet fabric is best for hot sleepers?

Go for a percale weave in 100% cotton or Egyptian cotton - both are naturally breathable and get crisper with every wash. The 200TC or 400TC Egyptian cotton options are particularly popular with warm sleepers. Bamboo is also worth considering, it is naturally temperature regulating and exceptionally soft. Avoid sateen weaves if you tend to overheat, as the denser finish retains more warmth.

What is the difference between percale and sateen flat sheets?

Percale has a crisp, cool, matte finish - ideal if you prefer that fresh, hotel-style feel or tend to sleep warm. Sateen has a smooth, silky surface with a subtle sheen that feels more luxurious to the touch but retains slightly more warmth. If you are unsure which to choose, percale is the more versatile everyday option. Sateen suits those who prioritise a softer, more indulgent feel.

What is Pima cotton and how does it differ from Egyptian cotton?

Both are premium long-staple cottons known for exceptional softness and durability, but they come from different origins. Egyptian cotton is grown in the Nile Delta and is widely regarded as the gold standard for bedding. Pima cotton, grown primarily in the Americas, has similarly long fibres and offers a beautifully smooth feel with a natural sheen. Belledorm's 450TC Pima Cotton flat sheet is a great option if you want luxury quality at a slightly lower price point than the top-tier Egyptian cotton ranges.

Is a higher thread count always better quality?

Not necessarily. Thread count is one factor, but fibre quality and weave construction matter just as much. A well-made 200TC Egyptian cotton flat sheet will often feel better and last longer than a cheap 800TC sheet made from inferior cotton. Belledorm's range runs from 200TC up to 1200TC, the right choice depends on your preference for feel and budget, not just the number on the label.

Can I use a flat sheet on its own in summer instead of a duvet?

Absolutely - this is one of the most practical uses of a flat sheet. During warmer months, a lightweight cotton or bamboo flat sheet on its own provides just enough coverage without the heat of a duvet. The 200TC percale and bamboo options are particularly popular for summer use thanks to their breathability and cool, crisp feel against the skin.

How do I get a hotel-style finish with a flat sheet?

Spread the sheet evenly over your fitted sheet with equal overhang on each side. Tuck the foot end firmly under the mattress first, then fold each bottom corner into a neat hospital corner, pulling the side overhang taut and tucking it under in a diagonal fold. Belledorm's cotton and Egyptian cotton weaves are particularly well-suited to this thanks to their natural structure and drape.

Can I order a sample before committing to a full flat sheet?

Yes - most Belledorm flat sheets have a sample option available so you can feel the fabric quality before buying. Look for the "Sample Available" label on individual product listings throughout the range. It is a particularly useful option if you are choosing between thread counts or fabric types for the first time.
