Complete Guide to UK Bunk Bed Sizes

UK bunk bed

Besides all the other important factors, the bed size makes a huge difference when buying a bunk bed for your room. The bed and mattress size make it easy to pick the right bed according to the available space. Whether you want to buy a triple bed, a children’s bunk bed with trundle, a themed bed, or any other, the dimensions are crucial to ensuring the bed fits your room properly.

This guide compiles all the UK bunk bed and mattress sizes to help you make the right decision.

Types of Bunk Bed Sizes

While typically double and 3 bed bunk beds come in single beds, also known as twin beds, there’s much more. You can also find most of these beds in a double or queen-sized variant for adults. Furthermore, some designs combine both beds to offer better solutions to your sleeping needs. The two standard sizes of bunk bed mattresses are:

Single/ Twin

The single or twin bunk bed has a structure spacious enough for a single or twin mattress. These beds are typically used for young children and teenagers, sometimes adults. Most hostels and dormitories also have single or twin beds. The standard twin bed mattress size is 90 x 190 cm.

Double/ Queen

You might also see bigger beds when buying a bunk bed. These queen or double beds are best suited for adults or two children sleeping in one bed. Many parents prefer queen bunk beds for children in less-spacious rooms compared to quad bunk beds. However, it is suggested to use each bunk for one person only. The small double or queen bed comes in 120 x 190cm, whereas a double bed mattress is 135 x 190cm.

Bunk Beds with Single Mattresses

Now that you know the measurement for each type of mattress usually found in bunk beds, you can choose from multiple bed designs and options.

Bunk Bed with Stair and Slide

The simple bunk bed is a two-tier bunk bed with one single bed on top of a double bed. It allows you to provide sleeping space for two individuals in place of one single bed. These beds use two single/ twin mattresses for the top and bottom bunk. They are the most suitable bunk beds for 7 foot ceilings.

Bunk Beds with Double Mattresses

Besides single mattresses, many bunk beds come with a queen or double-sized mattress for adults. Some of the most common types of bunk beds with double bed mattresses include:

  • Width: 240cm
  • Height: 175cm

Bunk Beds with Single and Double Beds

Now that you know the designs and options for single or double bed mattresses, it is worth mentioning that some beds combine a double and a single bed.

Single & Double Bunk Bed

The single and double bunk bed has a single bed on top of a double bed. While these beds are ideal for parents in the double bed and their kid in the top bunk, they are also a hit among siblings. Many people get these beds for three children sharing one room. However, these beds require a single mattress of 90 x 190 cm and a double mattress of 140 x 190 cm. They’re the perfect bunk beds for 7 foot ceilings, especially in bigger families.
