Choose a split bunk bed if you expect your children to move into separate rooms or separate beds in the next few years, because it converts into two complete singles. Choose a space saving bunk bed if your priority is fitting as much as possible into the room you have now, through built in storage, a trundle, a lower profile or a staircase with drawers. Put simply, a split bunk plans for change; a space saving bunk makes the most of today. If you need both, some designs combine a split frame with drawers or a trundle, though often with fewer storage features than dedicated space saving models.
You will find both types in our modern bunk beds UK sale range. Here is how to work out which one suits your family.
A split bunk bed is made from two separate single frames that stack together. When children no longer want to share, or when you move house, the top bed lifts off and both frames stand alone as normal single beds. The appeal is longevity: one purchase can serve a shared room now and two individual rooms later.
Space saving is a broad term covering bunk beds designed to squeeze extra function into the same footprint. Common features include:
These designs are usually fixed as bunks and are not intended to be separated, although there are exceptions.
Both approaches sit within the bigger picture of furnishing a bedroom well, which is why it helps to look at how they pair with other pieces in our bedroom furniture UK sale collection.
In a generous bedroom, a split bunk leaves plenty of space for a wardrobe, chest of drawers and play area. Storage can be provided by separate pieces, which can move with the beds if they are later separated.
In a small box room, every centimetre counts, and a space saving bunk can make a significant difference. Drawers under the bed or within the staircase can replace a separate chest of drawers entirely, freeing floor space for play or a small desk. If the room is very narrow, a design with a ladder at the end rather than the side may also help.
Ceiling height is often the deciding factor in UK homes, particularly in newer properties and loft conversions. Standard split bunks are similar in height to most traditional bunk beds. Some space saving designs are deliberately lower, giving the top sleeper more headroom in rooms where a full height bunk would feel cramped.
Measure from floor to ceiling and compare it with the bed height plus mattress depth on the top bunk. The child on top should be able to sit up comfortably. If headroom is tight, a low bunk or a mid sleeper may be safer and more comfortable than either standard option.
Top bunks are generally not recommended for children under six, so the age of the youngest child matters.
This is perhaps the most useful question to ask. If you are planning to move to a bigger home, convert a loft or free up another bedroom in the next few years, a split bunk keeps your options open. Each child takes a single bed into their new room, and you avoid buying two new frames.
If sharing is likely to continue for the foreseeable future, a space saving bunk may give you more day to day benefit. Its storage and features will be used every day for years, which can outweigh the flexibility of a split frame.
Families who regularly host friends, cousins or grandchildren often value a trundle. A pull out bed beneath the lower bunk provides a third sleeping space without taking up any extra floor when not in use. Trundles are more common on space saving designs, although some split bunks include them too.
If you need guest sleeping space only occasionally, a split bunk used as two singles side by side can also work well for visiting adults who would rather not climb a ladder.
Some designs combine the strengths of both. You may find split bunks with underbed drawers, or with a trundle that can be used beneath either single once separated. These hybrids can be a good compromise, though they usually offer fewer storage features than a dedicated space saving bunk and may have less finished looking singles than a dedicated split design.
If neither standard option feels quite right, standalone beds are also worth considering. Our modern children’s beds UK sale include single beds with storage that might suit a room where bunks are not essential.
Built in storage on a space saving bunk is efficient, but it stays with the bed. Separate storage, such as a wardrobe or chest of drawers, can move around the room or into another room as needs change. Our children’s wardrobes UK include compact designs that work alongside either type of bunk.
For more ideas on fitting storage into a room that two children share, our guide to storage furniture for UK homes where children share rooms covers wardrobes, drawers and wall shelving in detail.
Whichever approach you choose, check that the bed meets BS EN 747 and that the top bunk has guard rails on both sides. Stay within the maximum mattress depth marked on the frame. On split designs, make sure the joining hardware is secure every time the bed is restacked. On space saving designs, check that drawers and trundles run smoothly and cannot be pulled out completely by small children, and that staircases have a handrail where needed.
Appearance matters too, particularly in a room that children will spend years in. Split bunks tend to have a cleaner, more traditional silhouette, with four posts, simple end panels and a ladder. Because they are designed to look like ordinary beds once separated, they rarely include bulky storage, which keeps the frame visually light.
Space saving bunks are more architectural. A staircase with drawers, a deep base with storage and integrated shelves give them a built in feel, almost like a piece of joinery. In a small room this can look neat and intentional, especially in white or a pale wood finish that blends with the walls. In a larger room, a substantial space saving bunk can become the focal point, so it is worth keeping the surrounding furniture simple.
Consider how the bed will sit with the window, door and any alcoves. A staircase usually needs to sit at one end of the bed, which affects where the bunk can go. A split bunk with a vertical ladder is often easier to fit into an awkward layout, because the ladder can usually be fixed on either side.
It is natural to compare the two types on what they offer straight away, but it is worth thinking about the years ahead. A split bunk effectively gives you two single beds for later, which may save buying new frames when children move into their own rooms. A space saving bunk may save you buying a chest of drawers or a separate guest bed now. Neither is better in every case; the right choice is the one whose benefits you will actually use. Picture the room, and your family, a few years from now, and choose the design that still fits that picture.
Answering these honestly usually points clearly towards one design. You can compare split and space saving bunk beds, along with matching storage, at Furniture in Fashion, with free delivery to most UK mainland postcodes.
Most cannot, as their storage and staircases are built into the structure. A few hybrid designs can be separated, so check the product details if this matters to you.
A space saving bunk usually makes better use of a very small room, because built in drawers and staircases can replace separate furniture.
A well made split bunk with steel dowels and through bolts should feel just as steady. Keep all fixings tightened, especially after restacking.
If you regularly host sleepovers or visiting family, a trundle is very useful. It provides an extra bed without taking up floor space when it is not needed.
