A child’s bedroom has to work harder than almost any other room in the home. It is a place for sleeping, reading, getting dressed, storing toys, calming down after a busy day and, quite often, squeezing several functions into limited floor space. The bed sits at the center of all of this, so choosing it purely because the frame looks attractive can create problems later.
The right kids’ bed should fit the room properly, support a suitable mattress, feel comfortable when a child is sitting as well as sleeping, and leave enough usable space around it. Storage, headboard design and even the position of the bed can influence how practical and relaxing the entire bedroom feels.
That matters because the bedroom environment is closely connected with bedtime. NHS guidance recommends creating a calm, comfortable sleep environment and maintaining a predictable routine, while bedroom temperature, lighting, noise and distractions can all affect how easily children settle.
Rather than treating the bed as one item on a decorating checklist, it makes more sense to design the room around it.
Start with the Right Bed Size for the Bedroom
A common mistake is deciding which bed size you would like and then trying to make the rest of the furniture fit around it. Reverse that process.
Measure the room first. Note the position of the door, radiator, windows, wardrobes, drawers and other furniture that needs to remain accessible. Then decide how much of the available floor area the bed can reasonably occupy.
Standard UK mattress dimensions include 90 × 190 cm for a single, 120 × 190 cm for a small double and 135 × 190 cm for a double. King and super king mattresses are larger and also 200 cm long rather than the 190 cm length used by standard singles, small doubles and doubles.
Adeline Waterson’s current kids’ bed collection reflects this range, offering options from Single 3ft and Small Double 4ft through Double 4ft6, King 5ft and Super King 6ft.
Choose Between a Single and Small Double Based on How the Room Is Used
For a compact bedroom, a single bed is often the most sensible option. It gives a child a full-size sleeping surface while preserving more floor space for playing, a desk or storage.
A small double can work particularly well when the room is large enough to accommodate one comfortably. At 120 cm wide, it provides noticeably more sleeping space than a 90 cm single while remaining narrower than a standard double.
Think beyond your child’s current age, too. A bed chosen for a young child may still be in the room during the teenage years. In a sufficiently spacious bedroom, choosing a size with some room for growth can reduce the need to replace the complete bed simply because the child becomes taller or wants more sleeping space.
The key is not to buy the largest bed that physically fits. Choose the largest appropriate bed that still allows the bedroom to function comfortably.
Measure the Whole Bed, Not Just the Mattress
Mattress dimensions are only part of the calculation. Upholstered side rails, footboards and headboards can make the complete frame larger than the mattress itself, so check the manufacturer's finished dimensions before ordering.
Also consider what needs to happen around the bed. Can wardrobe doors open fully? Can someone make the bed without squeezing against a wall? Is there a clear route between the door and the sleeping area?
Storage mechanisms need their own clearance. Adeline Waterson, for example, offers configurations including standard bases and gas-lift storage on its children's upholstered beds; its own guidance recommends allowing sufficient opening space when selecting drawer storage.
A useful practical trick is to mark the proposed bed footprint on the floor with masking tape. Live with the outline for a day before ordering. You will quickly notice whether it interrupts normal movement through the room.
Match the Bed and Mattress to Everyday Comfort
A comfortable children's bed is more than a mattress on a frame. Children frequently sit in bed to read, listen to stories or relax, so the way the frame feels during these activities also matters.
This is where an upholstered headboard can be particularly useful. A padded surface creates a more comfortable backrest than leaning directly against a hard wall, metal rail or timber headboard. Adeline Waterson's children's collection uses upholstered frames and includes vertical-channel, bordered-panel and button-tufted designs, with multiple fabric and color choices.
The mattress still deserves equal attention. The National Bed Federation's consumer guidance recommends choosing a mattress that provides appropriate support and advises checking that separately purchased mattresses and bases are compatible. A washable mattress protector is also a practical addition because children's mattresses inevitably have to cope with occasional spills and accidents. 
Avoid choosing mattress firmness simply by assuming that "firmer is better." Comfort is individual. Consider the child's age, build, usual sleeping position and any specific health or sensory requirements, and follow the mattress manufacturer's age and suitability guidance.
Where possible, involve the child in the decision. The National Bed Federation's Bed Advice service also recommends giving children some input when choosing a bed, as they are ultimately the person who needs to feel comfortable using it.
That does not mean handing over every design decision. A sensible compromise is to let them choose elements that can change easily—such as bedding or accessories—while parents control practical decisions such as dimensions, construction and storage.
Let the Bed Solve Storage and Safety Problems Too
In many UK homes, children's bedrooms are relatively compact, which makes unused space underneath a bed valuable. Choosing a bed with integrated storage can reduce dependence on extra chests, boxes and freestanding cabinets.
Adeline Waterson's range, for example, includes under-bed storage configurations, with gas-lift storage designed to make the space underneath the mattress accessible from above.
Choose the storage system according to what you actually need to store:
-
Frequently used items such as bedding, pyjamas or everyday toys need storage that is quick and easy to access.
-
Seasonal items such as spare duvets, winter bedding and less-used toys can work well in deeper under-bed storage.
-
Very small bedrooms may suit lift-up storage better than drawers when there is insufficient side clearance for drawers to open comfortably.
Reducing unnecessary freestanding furniture can also simplify the layout, but bedroom safety still needs deliberate attention. RoSPA warns that unsecured chests of drawers and similar furniture can tip over when children attempt to climb them, so appropriate furniture should be secured according to manufacturer instructions.
Bed position matters as well. GOV.UK warns that looped blind cords can endanger young children, and safety guidance recommends keeping furniture children can climb away from hazardous cords around windows.
For bunk or high-sleeper designs, safety requirements become even more important. UK guidance refers to BS EN 747 for domestic bunk-bed safety, covering areas such as guard barriers, ladder design and potentially hazardous gaps.
In other words, the safest layout is not necessarily the one that photographs best. It is the one that considers how a child will actually move, climb and play in the room.
Build a Calmer Bedroom Around the Bed
Once the bed itself is right, the surrounding environment should help distinguish bedtime from daytime activity.
NHS children's health guidance recommends a bedroom temperature of roughly 16–20°C and emphasizes appropriate lighting, comfortable bedding and a sleeping environment that is not excessively stimulating.
Lighting deserves particular attention in the UK, where summer evenings can remain bright well beyond a young child's bedtime. Blackout curtains or blinds can make the room darker, although any blind system in a child's bedroom must also be selected and installed with cord safety in mind. Some children, however, dislike complete darkness, and NHS guidance notes that a small nightlight may be helpful where appropriate.
The bed can contribute visually to this calmer atmosphere. Rather than building the entire room around a passing cartoon character or trend, consider choosing a bed color that can survive several redecorations. Neutral cream, beige or grey frames can be updated with different bedding as tastes change, while a stronger color can turn the bed itself into the main feature.
Adeline Waterson currently offers its children's upholstered designs in a wide palette across fabrics including velvet, Naples, chenille, Coniston and other finishes, allowing the frame to be either a statement piece or a neutral foundation.
Finally, treat the bed as the destination of a consistent wind-down rather than the beginning of negotiations about bedtime. NHS advice for young children recommends starting a calming routine around 30 minutes before sleep, while children's health guidance also recommends minimizing bright electronic screens and maintaining a predictable environment.
A bedroom does not need to look empty to feel restful. It simply needs visual order. Keep the area immediately around the bed relatively calm and give toys, school materials and clothes clear places to go. For children who are particularly sensitive to stimulation, NHS guidance specifically notes that clutter, lighting, sounds and fabric textures can influence how comfortable the sleeping environment feels.
Frequently Asked Questions About Choosing a Kids’ Bed
What is the best bed size for a child in the UK?
A standard UK single measures 90 × 190 cm and is suitable for many children's rooms. A small double measures 120 × 190 cm and provides extra width where the bedroom has enough space. Choose according to the complete room layout rather than age alone.
Is a small double bed suitable for a child's bedroom?
Yes. A small double can be a practical long-term choice for a growing child or teenager, provided it does not reduce essential walking, storage or study space.
Are upholstered beds practical for children?
They can be. Upholstered headboards provide a padded surface for sitting and reading. For easier maintenance, choose an appropriate fabric and use the manufacturer's recommended cleaning method. Adeline Waterson's kids' range currently includes several upholstered designs and fabric choices.
Should a children's bed have built-in storage?
It is especially useful in smaller bedrooms. Under-bed storage can hold spare bedding, clothes or toys without requiring another large piece of furniture. Consider how the storage opens before choosing between drawers and lift-up storage.
How can I make my child's bed area more comfortable at night?
Start with a supportive, correctly fitted mattress, comfortable bedding, manageable room temperature and appropriate darkness. Keep unnecessary screens and stimulating clutter away from the sleeping area and maintain a predictable bedtime routine.
