Bunk Bed / Narrow Single Sheets

Belledorm's bunk bed and narrow single fitted sheets are sized for mattresses measuring 75cm x 190cm (2ft 6in x 6ft 3in) - narrower than a standard single (90cm x 190cm) and specifically designed for bunk bed frames, cabin beds, and narrow single divans.

The narrow single duvet cover (135cm x 200cm) is the same dimension as a standard single duvet cover - a single duvet fits a bunk bed, though it will overhang the sides. The fitted sheet is size-specific and will not fit a standard single mattress (90cm wide).

A bunk bed / narrow single fitted sheet measures 75cm x 190cm. A standard single fitted sheet measures 90cm x 190cm - 15cm wider at the same length. The two sizes are not interchangeable.

A standard single fitted sheet placed on a 75cm bunk bed mattress will have excess fabric that bunches at the sides and is difficult to tuck securely. Conversely, a narrow single sheet placed on a standard 90cm mattress will be too tight and pull free from the corners. Always confirm your bunk bed mattress width before purchasing, 75cm is narrow single, 90cm is standard single. Many bunk bed and cabin bed frames use the narrower 75cm width to reduce the overall footprint of the bed.

Yes, a standard single duvet cover (135cm x 200cm) fits a bunk bed and is the correct size to use with a single duvet on a narrow single mattress. The duvet cover will overhang the sides of a 75cm mattress more than it would on a 90cm single, but this is normal.

The practical consideration for bunk beds is ease of making the bed, particularly for upper bunks where access is restricted. Belledorm's range includes fitted sheets specifically sized for the 75cm narrow single mattress. The fitted sheet must be the correct narrow single size; the duvet cover can be standard single size. Always check the fitted sheet dimensions specifically rather than assuming a standard single set will fit.

Most bunk bed and cabin bed mattresses are 10-15cm deep - shallower than standard domestic mattresses, making a standard 30cm fitted sheet the correct choice for the majority of bunk bed setups.

Bunk bed mattresses are deliberately thinner to keep the total bed height manageable and reduce the risk of falls from upper bunks. A standard 30cm fitted sheet provides more than enough depth for most bunk bed mattresses. Extra deep (38cm) or ultra deep (46cm) fitted sheets are rarely needed for bunk beds unless a mattress topper has been added. If you are unsure, measure your bunk bed mattress depth before selecting a sheet depth.

To fully dress a bunk bed, you need a narrow single fitted sheet, a single duvet cover, and one pillowcase. The fitted sheet must be specifically sized for the narrow single (75cm x 190cm).

The complete bunk bed bedding list:

• Fitted sheet (75cm x 190cm) - must be specifically labelled as narrow single or bunk bed size

• Duvet cover (135cm x 200cm) - standard single size fits correctly

• Pillowcase - standard UK pillow is 48cm x 74cm; one required

• Flat sheet (150cm x 275cm) - optional

• Mattress protector - recommended, particularly for children's bunk beds

The key purchase to get right is the fitted sheet - confirm it is 75cm wide (narrow single) rather than 90cm wide (standard single).

Bunk bed fitted sheets are standardised at 75cm x 190cm across the UK bedding industry, but this is a less common size than standard single, always confirm stock availability and check the sheet dimensions carefully before purchasing.

The narrow single (75cm) is sometimes listed under different names by different retailers: "bunk bed sheet", "narrow single sheet", "2ft 6in sheet", or "cabin bed sheet" - all refer to the same 75cm x 190cm fitted sheet size. The fitted sheet is the size-critical item; single duvet covers and pillowcases are standard single size and widely available. If your bunk bed mattress measures 90cm wide rather than 75cm, you need a standard single sheet, not a narrow single.

UK single bed bedding from Belledorm follows the standard dimensions used across the British bedding industry, though fitted sheet depth varies depending on your mattress.

Fitted sheets are available in three depths: standard 30cm (12 inches) for mattresses up to 22cm deep, extra deep 38cm (15 inches) for mattresses up to 30cm deep including those with toppers, and ultra deep 46cm (18 inches) for the deepest luxury and adjustable mattresses. Always measure your mattress depth - including any topper or protector - before selecting a fitted sheet depth.

A standard Belledorm single fitted sheet (90cm x 190cm) fits a UK single mattress measuring 90cm wide by 190cm long - the most common single bed size in the UK, found in the majority of single beds, day beds, and children's beds.

The fitted sheet's length and width dimensions are fixed to the mattress size. What varies is the depth - the box measurement that wraps under the mattress edge. Belledorm offers single fitted sheets in 30cm (standard), 38cm (extra deep), and 46cm (ultra deep) depths to accommodate mattresses from basic 15cm sprung models through to luxury 35cm+ pocket sprung mattresses with toppers. If your single mattress is longer than 190cm - as is the case with some European and custom mattresses - a standard UK single sheet will not fit and you should check the long single range.

A UK single bed measures 90cm x 190cm (3ft x 6ft 3in). A small double measures 120cm x 190cm (4ft x 6ft 3in) - the same length but 30cm wider. The two sizes use entirely different bedding and sheets are not interchangeable.

The small double (also called a 4ft double) is a popular choice for guest rooms, teenagers, and adults who want more width than a single without committing to a full double. A single fitted sheet will not stretch to fit a small double mattress - attempting to do so will result in the sheet pulling free from the corners. If you are unsure which size your mattress is, measure the width: 90cm is single, 120cm is small double, 135cm is double. Belledorm stocks dedicated small double bedding at belledorm.co.uk/sheets/small-double-4ft.

Yes, a standard UK single bed (90cm x 190cm) is suitable for most adults, though taller adults over 6ft 3in (190cm) may find the length restrictive and should consider a long single (90cm x 200cm) instead.

Single beds are the standard choice for children aged 8 and above, teenagers, and adults in single-occupancy rooms, student accommodation, and holiday lets. The 90cm width is comfortable for a single sleeper of average build. For adults who move around during sleep or prefer more space, a small double (120cm x 190cm) provides significantly more room without requiring a full double bed frame. Belledorm's single sheet range covers 126 products across all fabrics and depths, from Basics Polycotton from £8.50 through to 100% Mulberry Silk from £234.60.

To fully dress a single bed, you need a fitted sheet, a duvet cover, and at least one pillowcase. A flat sheet is optional but recommended for those who prefer a layered or hotel-style bed setup.

The complete single bed bedding list:

• Fitted sheet (90cm x 190cm) - in your chosen depth: 30cm, 38cm, or 46cm
• Duvet cover (135cm x 200cm) - sized for a single duvet
• Pillowcase - standard UK pillow is 48cm x 74cm; housewife or Oxford style
• Flat sheet (180cm x 275cm) - optional, used between the fitted sheet and duvet
• Mattress protector - recommended to extend mattress life and add a hygiene layer
• Valance sheet - optional, used to conceal the bed base and divan legs

All items above are available in matching fabrics and colours across Belledorm's single range, making it straightforward to build a coordinated set from a single fabric family.

Yes, UK single bed sheet dimensions are standardised across the industry: fitted sheets are 90cm x 190cm, flat sheets are 180cm x 275cm, and duvet covers are 135cm x 200cm. Belledorm's single range follows these standard UK dimensions throughout.

The one variable is fitted sheet depth, this is not standardised and varies by product and brand. Always check the box depth (30cm, 38cm, or 46cm) against your mattress measurement before purchasing. The duvet cover size (135cm x 200cm) is also worth noting: it is designed to fit a single duvet tog, not a double duvet. Using a double duvet (200cm x 200cm) inside a single cover will result in bunching and poor fit. If you are buying bedding as a gift or for a property you cannot measure, standard UK single dimensions apply to the overwhelming majority of single beds manufactured since 2000.
