Best Bunk Beds – The Ultimate Bunk Bed Buying Guide (2026)
A bunk bed is one of the most practical pieces of furniture you can buy for a child's bedroom. Whether you're furnishing a shared room, making the most of limited space or simply creating a fun sleeping environment, bunk beds offer an excellent combination of practicality and value.
Today's bunk beds are available in a wide range of styles, from traditional wooden designs to modern storage bunk beds, triple sleepers and even bunk beds with integrated desks.
But with so many options available, how do you choose the right one?
This guide explains everything you need to know before buying a bunk bed, including safety, age recommendations, sizes, storage options and the features worth looking for.
Why Choose a Bunk Bed?
Bunk beds have remained one of the UK's most popular children's beds for decades because they maximise sleeping space without requiring a larger bedroom.
Instead of two single beds taking up valuable floor space, a bunk bed stacks one bed above another, leaving room for wardrobes, desks or play areas.
They're ideal for:
- Brothers and sisters sharing a bedroom
- Sleepovers
- Holiday homes
- Grandchildren staying over
- Small bedrooms
- Families wanting to future-proof a child's room
For many households, a bunk bed is the simplest way to create more usable space without compromising comfort.
Who Are Bunk Beds Suitable For?
Most manufacturers recommend that the top bunk should only be used by children aged six years and over.
The lower bunk can often be used by younger children, depending on the manufacturer's guidance and the specific design.
As children grow older, bunk beds continue to be popular throughout their teenage years, particularly where siblings share a bedroom.
Typical age guide
| Age | Recommendation |
|---|---|
| Under 6 | Top bunk not recommended |
| 6–8 years | Suitable for top bunk with supervision and safety rules |
| 9–12 years | Excellent choice |
| Teenagers | Many models remain ideal |
Always follow the manufacturer's recommended minimum age.
Different Types of Bunk Beds
Modern bunk beds are available in a surprising variety of designs.
Choosing the right style depends on your family, room size and storage needs.
Standard Bunk Beds
The traditional design features two single beds stacked vertically.
These remain the most affordable and space-efficient option.
Best for:
- Shared bedrooms
- Sleepovers
- Everyday family use
Storage Bunk Beds
Many models include integrated:
- Drawers
- Cupboards
- Shelving
- Bookcases
These reduce the need for additional bedroom furniture and help keep rooms organised.
Perfect for smaller bedrooms where storage is limited.
Triple Sleeper Bunk Beds
A triple sleeper usually combines:
- Single bed on top
- Double bed underneath
They provide sleeping space for three people without needing three separate beds.
Ideal for:
- Larger families
- Guest rooms
- Teenagers wanting more sleeping space
L-Shaped Bunk Beds
These position the beds at right angles rather than directly above each other.
Benefits include:
- Easier access
- Additional shelving
- Modern appearance
- Better use of awkward room layouts
Shorty Bunk Beds
Designed for younger children, shorty bunks are:
- Lower in height
- Shorter in length
- Easier to climb
They're particularly useful where ceiling height is limited.
Wooden or Metal Bunk Beds?
One of the biggest decisions is choosing between wood and metal.
Wooden Bunk Beds
Advantages
- Warm appearance
- Strong construction
- Timeless style
- Available in many finishes
- Usually quieter
Popular finishes include:
- White
- Grey
- Oak
- Pine
- Cashmere
Considerations
- Heavier
- Usually more expensive
- Harder to move once assembled
Metal Bunk Beds
Advantages
- Modern appearance
- Lightweight
- Affordable
- Easy to clean
Considerations
- Can feel less substantial
- May develop squeaks over time
- Often offer fewer storage options
For most family homes, wooden bunk beds remain the most popular choice.
What Mattress Size Do You Need?
Most UK bunk beds use:
90cm × 190cm UK Single mattresses
However, always check the manufacturer's recommendations before purchasing.
The top bunk usually requires a mattress below a specified maximum depth.
This ensures the guard rails remain high enough to provide effective protection.
Important Safety Features
Safety should always be your first consideration.
Look for:
- Full-length guard rails
- Strong ladder
- Wide ladder steps
- Secure fixings
- Rounded corners
- Sturdy frame
- Durable construction
Always tighten fittings periodically, especially during the first few months of use.
How Much Storage Do You Need?
Many modern bunk beds include built-in storage.
Options include:
- Under-bed drawers
- Cupboards
- Shelving
- Hidden compartments
- Book storage
If you're buying for a smaller bedroom, integrated storage can eliminate the need for additional furniture.
Measuring Your Room
Before ordering, carefully measure:
- Room width
- Room length
- Ceiling height
- Doorways
- Windows
- Radiators
Remember to allow enough headroom above the top bunk for your child to sit comfortably.
You should also leave space for climbing the ladder safely.
Choosing the Right Ladder
Different bunk beds use different ladder designs.
Some include:
- Straight ladders
- Angled ladders
- Wide wooden steps
- Reversible ladders
Wider steps are generally more comfortable for younger children.
Some premium models even include staircase access with built-in storage.
Are Bunk Beds Good for Small Bedrooms?
Yes.
They're one of the best furniture choices for smaller bedrooms because they double sleeping capacity while using little more floor space than a single bed.
The extra room created can be used for:
- Desks
- Wardrobes
- Toy storage
- Play space
This makes bunk beds particularly popular in family homes where children share a room.
What Should You Spend?
Prices vary considerably depending on:
- Materials
- Storage
- Size
- Brand
- Design
- Build quality
Generally speaking:
Basic bunk beds offer excellent value.
Premium models cost more but often include wardrobes, shelving, drawers and higher-quality construction that can last for many years.
Buying a well-built bunk bed is usually a better long-term investment than replacing a cheaper one after only a few years.

Our Buying Advice
A bunk bed is one of the smartest investments for families looking to maximise bedroom space without sacrificing comfort. Whether you're furnishing a shared bedroom, preparing for regular sleepovers or simply making better use of a smaller room, there's a design to suit almost every home.
Before buying, think about how the room will be used over the next few years. If storage is limited, consider a bunk bed with built-in drawers or shelving. If flexibility is important, look for a model that can later separate into two single beds. For younger children, lower or shorty bunk beds can offer extra peace of mind, while older children and teenagers may appreciate premium designs with wider sleeping areas and integrated storage.
Choosing a well-made bunk bed from a reputable manufacturer will provide years of reliable use and help create a bedroom that's both practical and enjoyable.
