What is a three-quarter size bed? A comprehensive guide

A three-quarter bed, also known as a small double, is wider than a single bed but narrower than a double bed. Three-quarter beds come in various styles and work well in bedrooms where space is limited.

What size is a three-quarter bed?

A three-quarter bed measures 4’0” x 6’3” (120 cm x 190 cm). It is 6 inches wider than a single bed and 6 inches narrower than a double bed, but it is the same length as both.

However, there is no standardisation for bed sizing, and the exact dimensions may vary depending on the manufacturer.

Who is a three-quarter bed suitable for?

Three-quarter beds suit smaller bedrooms or those who need more sleeping space than a single bed but less than a double.   

Children

Three-quarter beds are ideal for children as they provide more sleeping space for their growing bodies, whether transitioning from a cot to their first bed or upgrading from a single bed. The extra sleeping space is also useful for friends and family when sharing the bed during sleepovers.

A good-quality three-quarter bed can last several years if well-maintained, potentially taking children through to their teenage years.

Teenagers

Three-quarter beds are perfect for teenagers transitioning from a single bed. Teenagers typically require more sleep than adults, so having a larger bed may improve their sleep as it gives them more space to stretch out and turn over. The bed could also be used as a spare bed in the future if and when the teenager leaves home.

Single adults

Three-quarter beds are ideal for single adults who need more sleeping space as they provide enough room to stretch out and turn over comfortably.

Guest bedrooms

Small double beds are a practical option for smaller guest bedrooms as they can accommodate two people without overwhelming the space. They may also leave room for other bedroom furniture, such as a wardrobe, chest of drawers, or bedside tables.  

Many three-quarter beds come with built-in storage like drawers or lift-up ottomans, providing valuable space for bedding, clothes, books, and other items.

Multi-functional bedrooms

4’0” beds are ideal for multi-functional bedrooms as they take up less space than double beds while still being suitable for occasional use by couples. This leaves extra space for other furniture, such as a study desk or a sofa for lounging.

Properties with access restrictions

Three-quarter beds are well-suited for properties with access restrictions where larger beds are not feasible. Their smaller size makes them well-suited for loft conversions, studio apartments, and cottages, as they are easier to manoeuvre through doorways, under low ceilings, up narrow staircases, and around tight bends.

Are three-quarter beds suitable for couples?

Although a three-quarter bed can accommodate couples, it can feel cramped. Each person only gets 2 feet of sleeping space, less than a baby in a cot. Couples are more likely to sleep better in larger beds, where they have more space and are less likely to disturb each other.

A three-quarter bed may be better suited as an occasional bed for couples who don’t mind a cosy sleeping space. Choosing a bed with good edge support can help extend the usable sleeping area.

Are three-quarter beds more expensive?

Three-quarter beds are usually the same price as double beds. Although smaller in size, some manufacturers consider them non-standard.

Are three-quarter beds kept in stock?

Three-quarter beds are not as widely available as other bed sizes like singles, doubles, and kings and may be made to order. Delivery can take several weeks, so it is best to avoid making plans, such as inviting guests, until the bed arrives.

Types of mattresses for three-quarter beds

Different types of mattresses are available for three-quarter beds. Although your choice of mattress depends on your needs and preferences, ensuring it is compatible with your bed base is essential.

Open coil mattresses

Open coil springs are commonly used in low to mid-end mattresses. They are ideal for budget shoppers looking for a mattress for a child, teenager, or guest bedroom. Open coil mattresses generally feel firmer and bouncier than other mattresses, which means that sleeping partners are more likely to disturb each other when they move in bed.

Pocket spring mattresses

Pocket springs are smaller, softer springs that work independently and conform well to body shape. As each spring is independent, couples are less likely to roll together or disturb each other in bed.  Pocket springs provide better-targeted support than coil springs, making them ideal for regular use.

Memory foam mattresses

Memory foam moulds and adapts to the body. It offers excellent pressure relief and can help alleviate aches, pains, and numbness. Memory foam has a dense cell structure, which can trap heat within the mattress and make it feel warmer than other mattresses.

Latex mattresses

Like memory foam, latex conforms well to body shape and provides excellent pressure relief, but it has a slightly bouncier feel and can be more expensive.

Hybrid mattresses

Hybrid mattresses combine foam and springs. They are typically constructed with a 1 to 4-inch latex or memory foam comfort layer with a spring unit underneath for support. Hybrid mattresses tend to be deeper than regular mattresses and can be more expensive.

Bed bases for small double beds

There are several types of bed bases available in small double sizes, including divans, bed frames, and ottomans. Your choice will likely depend on your style preferences, room size, lifestyle, and budget. Whichever bed base you choose, ensure it is compatible with your mattress.

Divans

A divan base is an upholstered box, usually fitted with castors or legs. Divans are ideal for smaller rooms, as the base is usually the same size as the mattress and does not take up additional room space.

Divans typically have either a solid or sprung base. A solid base or platform top is usually made from hardboard and provides a firmer sleeping surface. In contrast, sprung divans have an interior sprung unit mounted on the frame for extra support and cushioning.

Many divans come with built-in storage, such as drawers or ottomans, offering valuable space for bedding and clothes. They may also be available in various fabrics, with matching headboards, allowing you to tailor the look to suit your bedroom décor.   

Divan bases often come in two sections, making them easier to manoeuvre into bedrooms.

Bed frames

Bed frames come in various styles, including wood, metal, fabric, and leather. They typically include a headboard, footboard, and side rails that attach to create the frame. Most bed frames have slats to support the mattress, though some may have a metal or wire grid.  

Bed frames generally take up more space than divans because the mattress typically sits inside the frame. It is important to measure the bedroom space beforehand to ensure the bed fits and leaves enough room to move around it.

Bed frames are usually flat-packed for easier bedroom access and often take longer to assemble than divans.

Will standard double bedding fit a 4’0” bed?

Standard double bedsheets are wider and won’t fit properly on a 4’0” bed. However, you can use a double duvet if you don’t mind the extra overhang. Fortunately, small double bedding is becoming more common and easier to find.

What are the alternatives to a three-quarter bed?

There are several alternatives to three-quarter beds, but your choice will be influenced by who will use the bed and how often.

Wider single beds

Some manufacturers offer bespoke sizes where they can produce beds that fall between a single and a small double bed, such as 3’3”, 3’6”, or 3’9” wide. These bespoke sizes usually cost more, and you will also require special-size bedding.

Trundle beds

Trundle beds typically consist of a main bed with a pull-out bed underneath. They are ideal for smaller bedrooms because the underbed only takes up space when in use. The underbed often has legs, allowing it to be raised to the same height as the main bed.

However, trundle beds usually come with thinner mattresses to allow the underbed to fit under the main bed easily. They may not feel as comfortable as regular beds and may be unsuitable for regular adult use.

Air beds

An air mattress, also known as a blow-up bed, is an inflatable mattress typically made from materials like PVC, rubber, or plastic. Air mattresses inflate quickly, are lightweight, and are easy to store, making them ideal for guests.

Sofa beds

A sofa bed is a couch that converts into an occasional bed, making it ideal for a multi-purpose room. While there are different types of sofa beds, they typically have thinner mattresses and are not as comfortable as standard mattresses for sleeping.

Sofa beds can also be heavy, making getting them upstairs challenging. You also need to ensure there is enough room space to convert the sofa into a bed.

Final thoughts

A three-quarter bed is the perfect compromise when you need a bed larger than a single but can’t quite accommodate a double. However, it may be impractical for couples who share a bed regularly due to its smaller size.
