Trundle Beds for Small Bedrooms
Trundle beds for small bedrooms provide a practical way to add a second sleeping space without permanently occupying extra floor area. The pull-out section slides underneath the main bed during the day, freeing up valuable room in compact UK homes.
What is a Trundle Bed?
A trundle bed consists of a main bed frame with a lower bed on wheels or castors that tucks away neatly beneath it. When needed, you simply pull it out to create two separate sleeping areas. Most models use a standard single mattress on the trundle, while the main bed can range from single to small double. This design suits children's rooms, guest bedrooms or studio flats where floor space is limited.
UK trundle beds must comply with fire safety regulations for upholstered furniture.
Benefits for Small Bedrooms
In rooms shorter than 3 metres wide, a trundle bed maximises usage by keeping the secondary sleeping area hidden. During the day the room can function as a play space, study area or home office. At night it quickly converts for sleepovers, visiting family or siblings sharing. Many designs double as daybeds, allowing the main bed to serve as seating with scatter cushions.
Compared with bunk beds, trundles avoid the 16cm guard rail height requirement above the mattress and are suitable for children from age 3 rather than the recommended minimum of 6 for top bunks. They also eliminate climbing ladders, reducing fall risks in tight layouts.
Space-Saving Checklist
- Measure your floor space: allow at least 60cm clearance on the pull-out side for easy access.
- Check ceiling height if considering a high-sleeper version; most need 220cm clear.
- Decide between single or small double main bed based on who uses the primary bed.
- Confirm the trundle accepts a standard single mattress and note any depth limits.
- Look for models on castors with brakes for safety on carpet or hard floors.
Popular Types of Trundle Beds
Daybed trundles work especially well in small bedrooms because the main frame sits low and can be used as a sofa. Wooden bunk beds with optional trundles offer future-proofing as children grow. Fabric upholstered options add softness and colour while meeting UK fire safety standards (BS 7177).
For very compact rooms, choose a model where the trundle sits only 15-20cm off the floor to minimise the overall height of the main bed. Montessori-style low beds with trundles also reduce visual bulk in small spaces.
Explore our full Trundle Beds range to see all options. Families often pair these with practical Kids' Beds With Storage for extra toy or clothing space without taking more floor area.
Choosing the Right Size
UK mattress sizes for trundle setups typically use small single (75x190cm), single (90x190cm) or small double (120x190cm). EU sizes such as 90x200cm will not fit standard UK trundle frames. Always verify exact dimensions on the product page before buying.
| Bed Type | Main Mattress Size | Trundle Size | Best For |
|---|---|---|---|
| Single Daybed | 90x190cm | 90x190cm | One child + occasional guest |
| Small Double | 120x190cm | 90x190cm | Shared children's rooms |
| High Sleeper with Trundle | 120x190cm | 90x190cm | Rooms needing desk space underneath |
If your child still uses a cot bed (70x140cm), consider a toddler transition model before moving to a full trundle system. For older children, a small double main bed offers more long-term flexibility.
Recommended Trundle Beds for Small Spaces
The Flair Ellis Single Bed with Trundle Beige Woven Fabric suits narrow bedrooms perfectly because its compact single frame and pull-out design keep the footprint minimal when closed.
The Flair Aurora Khaki Green Velvet Daybed With Trundle works as both seating and bedding, making it ideal for small bedrooms that double as living areas during the day.
Younger children benefit from the Noomi Iris Daybed with Trundle White (FSC-Certified) thanks to its low height and sustainable wooden construction that fits neatly against walls in rooms with limited width.
For a more playful option that still saves space, the Flair Bea Wooden Bunk Bed with Trundle combines raised sleeping with a pull-out guest bed while meeting BS EN 747 safety rules.
Many shoppers also view Kids' Beds and Kids Single Beds alongside trundle models to compare styles.
Pairing with Mattresses and Accessories
Choose a thin single mattress (maximum depth as stated on the product page) for the trundle to ensure it slides back under the main bed. A standard single mattress from our Single Mattresses range pairs well with most trundles.
For the main bed, small double mattresses offer more comfort for adults or growing teens. Add soft furnishings such as cushions or throws from our Soft Furnishings to turn a daybed trundle into comfortable daytime seating.
Consider adding under-bed storage drawers if the trundle model allows, or pair with bedroom furniture that keeps the rest of the room tidy. Wooden frames from brands like Flair and Noomi provide durability while meeting all UK fire safety requirements.
Practical Decision Rules
- If the room is under 2.5m wide, select a single or daybed trundle rather than a small double.
- Prioritise models with wheels that lock for safety on both carpet and wooden floors.
- For children under 6 avoid any raised designs; stick to low daybeds or floor-level trundles.
- Check that the trundle height plus mattress does not exceed the clearance under the main bed.
- Measure twice: the pulled-out bed needs space equal to its length plus 30cm for access.

Frequently asked questions
Can a trundle bed fit in a box room?
Yes. Most single trundle daybeds have a closed footprint that fits compact rooms. Measure your room carefully and allow 60cm clearance on the pull-out side. Daybed styles sit lower than standard beds, reducing visual height in small bedrooms.
What age is a trundle bed suitable for?
Trundle beds suit children from around age 3 because they sit low to the ground with no ladders. Unlike bunk beds which require children to be at least 6 years old due to BS EN 747 guard rail rules, trundles have fewer height restrictions. Always supervise young children.
Do I need a special mattress for the trundle?
No. A standard single mattress usually fits the trundle. Check the exact maximum mattress depth on the product page so the trundle slides back underneath.
Are trundle beds expensive to buy?
Prices vary by material and design. Fabric daybed trundles from Flair and Noomi offer good value because they serve as seating too. Wooden bunk beds with trundles cost more but provide longer use. Compare options on the product pages for current pricing and stock.
Can adults sleep on a trundle bed?
Yes, for occasional use. The trundle section is usually a standard single. For regular adult guests consider a small double main bed with single trundle. Check weight guidance on each product page. Daybed styles often have stronger frames suitable for adults.
