Single Bed Buying Guide for Kids & Guests

A single bed is one of the hardest-working pieces of furniture in a home, doing service in children’s rooms, box rooms and guest spaces alike. This guide walks you through the standard UK sizes, the frame styles worth knowing, clever storage options and the safety details that matter most for younger sleepers. By the end you’ll know exactly which single bed suits your room, your budget and the person sleeping in it.

1. Single bed sizes explained

In the UK, a standard single measures 90cm wide by 190cm long (roughly 3ft x 6ft 3in). It is the go-to size for children moving out of a cot bed, for teenagers, and for guest rooms where floor space is at a premium. If the sleeper is tall, a small double or a longer frame can be worth seeking out, though the standard 190cm length suits most people comfortably into their teens and beyond.

It helps to picture the whole footprint before you buy. A frame adds a few centimetres around the mattress, so always plan for the frame’s external dimensions rather than the mattress alone. Here is how the common single-family sizes compare.

If you think the sleeper may soon need more room, it is worth reading our UK bed sizes guide before committing, so you can weigh a single against a small double or a full double bed.

2. Who is the bed for?

The right single bed depends heavily on who will be sleeping in it. A bed for a five-year-old has very different priorities from one destined for a guest room, so it pays to be clear about the main use before you shop.

• Young children: a low frame height makes getting in and out safe and independent, and rounded edges reduce bumps.
• Teenagers: sturdiness and storage matter, as the bed often doubles as a place to lounge, study and store belongings.
• Guests: comfort and a welcoming feel take priority, along with a mattress that suits a range of body types.
• Multi-use rooms: a day bed or trundle keeps floor space free for the room’s other purpose.

Being honest about the primary sleeper stops you overspending on features you don’t need, or worse, buying a frame that a growing child outgrows within a year or two.

3. Frame styles and materials

Single beds come in a wide range of styles, and the frame you pick sets the tone for the whole room. The most common options are:

• Metal frames: light, affordable and easy to move, with a classic slatted look that suits both children’s and guest rooms.
• Wooden frames: warm and hard-wearing, ideal if you want the bed to grow with a child and coordinate with other bedroom furniture.
• Upholstered frames: a padded headboard adds comfort for reading or watching a screen, a nice touch in a teen or guest room.
• Day beds: styled like a sofa by day and a bed by night, perfect for rooms that need to work twice as hard.

Whatever the material, check the slat system. Sprung slats flex gently and cushion the mattress, while solid slats give a firmer feel. A well-built frame with closely spaced slats supports the mattress evenly and helps it last. Browse the full range of single beds to see how these styles look in practice, and if you want the bed to match a wardrobe or drawers, our bed frame guide covers coordinating a whole scheme.

4. Storage-savvy single beds

Single beds often live in the smallest rooms, so the space beneath them is precious. Several frame types are designed to reclaim it:

• Drawer beds: one or two built-in drawers slide out from the base, ideal for bedding, out-of-season clothes or toys.
• Ottoman beds: the whole mattress platform lifts on gas struts to reveal a deep storage void underneath, a brilliant use of space in a box room.
• Cabin and mid-sleeper beds: raise the sleeping surface to free up room below for a desk, drawers or a play den.
• Trundle beds: hide a second mattress on a pull-out frame, handy for sleepovers without needing a permanent second bed.

If the room is tight, an ottoman bed often gives the most storage per square metre because it uses the entire footprint of the bed. Just remember to leave clearance for the base to lift or for drawers to open fully. For rooms that still need more, pairing the bed with a slim bedside table keeps essentials to hand without crowding the floor.

5. Safety for children’s rooms

For younger children, safety features are not optional extras but the heart of the decision. A few checks make all the difference:

• Frame height: a lower bed reduces the distance of any tumble and lets small children climb in and out independently.
• Guard rails: useful for children who move from a cot, and essential for the top bunk of a bunk bed.
• Rounded corners: softer edges lower the risk of knocks during play.
• Sturdy construction: children treat beds as trampolines and forts, so a solid frame with secure fixings is a must.

If you are considering a bunk or high sleeper, follow the manufacturer’s minimum age guidance, which is typically six years and over for the upper bunk. Check that the ladder is secure and that gaps in guard rails are small enough to prevent a child slipping through. A well-lit room helps too, so a small lamp on the bedside or a soft light makes night-time trips safer.

6. Choosing the right mattress

A frame is only ever half the story, and the mattress is what actually determines a good night’s sleep. For a single bed you’ll want a mattress that matches the sleeper’s weight and preferences rather than simply the cheapest that fits.

Children generally suit a medium-firm mattress that supports a growing spine, while teenagers and adult guests may prefer a little more cushioning. Open-coil and pocket-sprung options both work well in a single, with pocket springs offering more responsive, individual support. Foam and hybrid mattresses are also popular for their pressure relief. Whatever you choose, make sure the depth suits the frame, especially with guard rails or a trundle, where an overly deep mattress can reduce the height of the safety rail.

Our mattress guide breaks down firmness, springs and foam in detail, and you can see single-size options in the mattresses collection. If the bed is for an occasional guest, a slightly firmer mattress tends to please the widest range of visitors.

7. Getting a guest room right

A guest room single bed should say “welcome” the moment someone walks in. Because guests use the bed only occasionally, you can prioritise looks and comfort over heavy-duty storage, though a drawer or two is always appreciated for stowing a spare duvet.

An upholstered headboard or a smart wooden frame lifts the room instantly, and layering good bedding, a couple of cushions and a soft rug underfoot makes a plain space feel considered. If the room doubles as a study or hobby space, a day bed pushes against the wall like a sofa during the day and frees the floor. Finish the scene with a mirror to bounce light around and a bedside surface for a guest’s phone, glasses and a glass of water.

8. Measuring and planning your room

Before you buy, measure the room properly so the bed fits and the space still works. Note the wall length where the bed will sit, then check that doors, wardrobes and drawers can still open with the bed in place. Leave a clear walkway of at least 60cm down any accessible side, and more if a child needs room to play.

Remember to account for the frame’s external size, not just the mattress, and think about the height of any headboard against a window or radiator. If the bed is going upstairs or round a tight landing, measure doorways and the turn on the stairs too, since flat-packed frames are far easier to manoeuvre than pre-assembled ones. Our measuring guide walks through this step by step, and the interactive Will It Fit planner lets you test the layout before anything arrives.
