The Ultimate Guide to Bunk Beds in 2026

The right bunk bed is the one that fits your room, your children’s ages and the way the space is used, built to the UK safety standard BS EN 747 and paired with mattresses of the correct depth. Choose the type first (standard, triple, L shaped, low or with storage), then the material, then the details such as ladder style, guard rail height and whether the frame splits into two single beds.

This guide brings together everything to consider, from measuring the room to looking after the frame for years to come. You can browse our full range of modern bunk beds UK sale alongside it as you work through each step.

Why families choose bunk beds

Bunk beds solve a very British problem: bedrooms that are smaller than we would like. Stacking two beds frees floor space for play, study or storage. They also suit sleepovers, visiting relatives and holiday homes, and many children simply enjoy them.

A good frame can be part of a family’s home for a decade or more, especially if it converts into separate beds later. That long life makes it worth choosing carefully. To see how a bunk bed fits with the rest of the room, take a look at our wider bedroom furniture UK range for matching storage and finishes.

The main types of bunk bed

Standard bunk beds

Two single beds stacked directly above one another. They take the smallest footprint and suit most rooms. Many split into two separate singles.

Low bunk beds

Shorter frames with less height between bunks. They suit rooms with lower ceilings and younger children, and they are easier to make up.

Triple bunk beds

Three sleeping spaces, either stacked or with a wider lower bunk. They need generous ceiling height and suit larger families or holiday lets.

L shaped bunk beds

The lower bed sits at a right angle to the upper one, leaving space underneath the top bunk for a desk or storage. They take more floor space but feel less enclosed.

Bunk beds with storage

Frames with drawers beneath the bottom bunk, or a staircase with drawers built into each step. These are especially useful in small rooms.

Bunk beds with a trundle

A third bed slides out from underneath, ready for guests. When not in use, it stays hidden.

Measuring your room properly

Ceiling height is the measurement people most often forget. The person on the top bunk needs to be able to sit up without hitting their head, so measure from the floor to the lowest point of the ceiling where the bed will stand, including any beams, light fittings or sloping sections.

Also measure the floor area including the ladder or staircase, the swing of the door and any wardrobe doors, and the position of windows and radiators. Leave space to walk along the side of the bed and to reach the bottom bunk to change sheets.

Finally, measure the route into the room. Hallways, landings and turns on the stairs can be narrower than expected, especially in older terraced houses.

Choosing the right material

Solid wood

Pine, oak and other hardwoods feel warm, sturdy and quiet. They can be refinished, and the look suits traditional and contemporary homes alike.

Engineered wood

Frames made from MDF or particleboard with a painted or wood effect finish are lighter and come in a wider range of colours. Look for a sturdy construction and good quality fixings.

Metal

Slim, strong and easy to clean. Metal frames suit modern and industrial rooms and work well in smaller spaces because they look lighter.

Safety: what to look for

Safety is the most important part of choosing a bunk bed. The points below are general guidance; always follow the manufacturer’s instructions for your specific frame.

• Standard: choose a bed that meets BS EN 747, which covers structure, guard rails and gaps.
• Age: the top bunk is not recommended for children under six.
• Guard rails: the top bunk should have rails on all sides, with only a gap for the ladder.
• Mattress depth: never exceed the maximum depth stated, so the guard rail stays high enough above the mattress.
• Ladder: it should be fixed firmly and have treads that are comfortable for bare feet.
• Position: keep the top bunk away from ceiling lights, fans and windows where possible.

Check fixings regularly, as bolts can loosen with use. Teach children to use the ladder rather than climbing the frame, and to keep the top bunk free of games that involve jumping.

Setting simple bunk bed rules

Children tend to follow rules they helped to make. Agree a few simple ones together when the bed arrives: one person on the top bunk at a time, always use the ladder, no jumping and no hanging anything from the guard rails. Keep the top bunk free of heavy toys and make sure the floor beside the ladder stays clear, so nobody trips when climbing down at night.

Ladders and staircases

A straight ladder takes the least floor space and can often be fitted on either side. An angled ladder is easier to climb for younger children. A staircase is the easiest of all and adds storage, but it needs more floor area. Think about who will use the bed at night, half asleep, and choose accordingly.

Mattresses for bunk beds

Most bunk beds take UK single mattresses, but check the dimensions for your frame. Depth is the key limit, especially on the top bunk. A supportive mattress matters for growing bodies, so do not compromise on comfort just because the depth is restricted. Our mattresses UK sale range includes single options with clearly stated depths.

Bunk beds or separate beds?

Bunk beds save floor space, but they are not always the answer. Older children or teenagers may prefer their own beds, especially if they have different bedtimes. Our children’s beds UK range includes cabin beds, mid sleepers and single frames, which can be a good alternative when a bunk is not quite right.

If you are considering single beds instead, our guide to upholstered single beds for UK children and teenagers compares the options for older children.

Styling a bunk bed room

A bunk bed is a large piece of furniture, so the rest of the room should support it rather than compete. Pale walls keep the space feeling open, and coordinating bedding on both bunks helps the bed read as one piece. Give each sleeper a small light, a shelf and a hook for their own things.

Storage is especially important in a shared room. Drawers beneath the bottom bunk, baskets on open shelves and a clear system for each child’s belongings keep the room calm. Our article on storage furniture for UK homes where children share rooms goes into this in more detail.

Bunk beds for different situations

Siblings sharing full time

Choose a sturdy frame with generous storage, and give each child their own light, shelf and bedding. A frame that splits later is especially useful as children move into their teens.

Occasional guests and sleepovers

A frame with a trundle or one that sits comfortably in a spare room works well. Neutral bedding makes it suitable for visiting adults as well as children.

Holiday homes and lets

Durability and easy cleaning matter most. Check weight ratings carefully, as adults may use the beds, and choose finishes that are simple to touch up between stays.

Small flats

Low or compact frames, built in drawers and slim ladders help make the most of limited floor space. Measure access routes before ordering.

Assembly and care

Most bunk beds arrive flat packed. Build the bed in the room where it will stay, with two people, and follow the instructions in order. Tighten every bolt fully, then check them again after the first few weeks as the frame settles.

For care, dust and wipe the frame regularly, oil or wax solid wood as recommended, and check ladders, slats and guard rails every few months. Small repairs done early keep the bed safe and extend its life.

Planning for the future

Children grow quickly, and their needs change. A frame that converts into two singles lets you separate siblings later, move a bed into a guest room or take one to a new home. Choosing a neutral finish also makes the bed easier to restyle as tastes change.

Frequently asked questions

What age is suitable for the top bunk?

The general UK guidance is that children under six should not sleep on the top bunk. Older children should still be taught to use the ladder and avoid rough play.

How much ceiling height do I need for a bunk bed?

There must be enough space for the person on the top bunk to sit up comfortably. Measure from the floor to the lowest point of the ceiling and compare it with the frame height plus the mattress and a generous gap.

Can bunk beds be split into single beds?

Many can. Check the product details for a convertible or separable design, and make sure any extra parts needed are included.

Are bunk beds suitable for adults?

Some are. Look for a frame with a weight rating that comfortably covers adult use and a mattress size that suits taller sleepers.

What is the safest type of ladder?

A staircase or angled ladder is easier to climb than a vertical one, particularly for younger children. Whatever the design, it should be fixed firmly to the frame.
