Bunk beds are combination of two beds in one. To help save space, one bed frame sits on top of the other in a single frame construction. They’re most popular for two siblings who share the one bedroom. They’re also popular in hostels, dormitories, and the military. That’s because they’re a superb solution for saving valuable floor space in small rooms.

What age is appropriate for bunk beds?

Bunk beds are most suited to children between the ages of 4 and 16. Importantly, children between 4 and 6 years old should only sleep in the lower bunk. This ensures maximum safety. For those aged 6 to 16, the side‐guards which are a must‐have feature, will keep them safe and secure all night long.

Do you need a special mattress for a bunk bed?

Most often, bunk beds require mattresses that are less than 15cm deep – especially for the top bunk. to This ensures maximum safety and allows the bunk’s side guards to do their job properly. In length and width, bunk bed mattresses are usually the same as a typical single mattress.

Can you use a memory foam mattress on a bunk bed?

You can’t use memory foam in a bunk bed mattress as there isn’t enough space within the maximum 15cm depth. However, you can choose between pocket spring, traditional spring and standard foam. There’s also the option for waterproof inner covers and water repellent outer covers. The outer layer is easily removed for a quick wipe clean if any accidents happen in the night.

How thick should a bunk bed mattress be?

As mentioned, 15cm is the typical required depth for a bunk bed mattress. This ensures the safety features work as designed and keep your youngsters safe. Despite this requirement, there are no further limitation in terms of features. For example, you can choose foam and traditional spring, with options for wipe clean and hypoallergenic materials.

What are bunk beds?

Bunk beds are two single beds stacked vertically, usually with a ladder for easy access to the top bunk. One sits above the other to form a single unit and they’re great space saving beds for kids. For bedrooms that are low on floor space, or for shared bedrooms, a bunk bed is the perfect choice. You can find several different styles in our bunk beds range, from wooden to metal and upholstered designs.

What ages are they suitable for?

Bunk beds are appropriate for all ages above 4 years. However, regulations state that children under 6 years should only use the bottom bunk. If your little ones are younger, it's best to opt for cots or toddler beds instead.

As one bed stacks above another, bunk beds are ideal for room shares and bedrooms that don’t offer a lot of space.

Are bunk beds safe?

All bunk beds sold in the UK must conform to British Standard Specification 1 BS EN 747. These safety standards require bunk beds to:

Have fixed guard rails on both sides of the top bunk.
Be solid in their construction.
Contain no sharp edges.
Have no gaps larger than 75mm.

View our bunk bed safety guide for more information on safety features and regulations.

Our bunk beds have been carefully crafted with safety features in the design to prevent them breaking, tipping over, collapsing, or falling. On the top bunk, the guard rails are raised beyond the mattress depth to ensure your youngster can’t fall out.

There is no recommended weight limit to our bunk beds. However, we’d recommend that only one person sit or sleep on the top bunk at a time to keep the bed balanced and ensure that everyone’s safe.

What different types of bunk beds are available?

Bunk beds come in a range of styles, colours, and designs to suit the tastes of boys and girls.

Standard

A standard bunk bed is two beds, stacked one on top of the other to save space in small bedrooms. Bunk beds usually come with a small ladder for easy access to the top bunk, however, some come with stairs, which are easier to climb but take up more space.

Wooden

Wooden bunk beds are sturdy, easy to put together and are made from high quality wood. As a result, they’re long-lasting and can be re-painted to freshen up a room. A classic wood bunk bed is a timeless piece for a children's bedroom as they grow-up and their tastes change, these remain stylish and practical for years to come.

Metal

Sturdy, easy to clean, and long‐lasting, metal bunk beds are great for a range of room styles. They’re ideal for older kids still sharing a room, offering a more adult-looking design compared to painted wood.

Bunk Bed with Storage

As well as having two beds, some bunk beds offer cupboard space as another way of saving space in a small room. There’s often shelving within cupboards making it easy to store clothes, bedding, shoes, and whatever you see fit.

Some bunk beds with storage have shelves and is usually designed so that the shelves sit against a wall, allowing easy access and a safe space for books, lamps, and ornaments. You can also get a bunk bed with under-bed drawers for extra storage, which is perfect for keeping spare bedding, clothes, or toys out of sight.

What size are bunk beds?

Bunk beds are typically 39 inches (99cm) in width, 79 inches (200cm) in length and 65 inches (165cm) in height. However, some bunk beds differ slightly in size depending on the style and design of the bed frame.

Always measure the allocated room space before making your purchase and ensure that there is at least 24 inches (61cm) of space between the top bunk and the ceiling.

It's also worth noting that bunk beds aren't the only beds which maximise space in a child's room or a guest room. If you’re looking for a specific bed for a guest room, check out our guest beds. Or we have other great space saving kids beds, including mid sleepers, high sleepers, and cabin beds.

What mattresses can you use with bunk beds?

Top bunk mattresses should be no thicker than 15cm to ensure the guard rails are at the correct and safe height. Therefore, we recommend pocket spring, traditional spring, or kids mattresses.

Most bunk beds will be suitable for single, Euro single, and small single size mattresses depending on the dimensions and style of the bunk bed frame.
