Choosing Bunk Beds for Different Ages

Bed Kingdom guide · Updated October 2026 · 3 min read

Parents choosing bunk beds for different ages need to match the style, height and features to the child’s developmental stage, room size and safety needs. Toddlers require low shorty bunk beds with easy access, school-age children benefit from standard or staircase wooden bunk beds that meet BS EN 747, while teenagers often need larger configurations with desks or storage.

Toddler Bunk Beds (Ages 2-5)

For toddlers the priority is low overall height and easy ladder or staircase access. Shorty bunk beds keep the top bunk close to the floor, reducing fall risk. The top-bunk guard rail must rise at least 16 cm above the mattress surface; always use the mattress depth stated by the maker. Cot bed mattresses measure 70x140 cm and fit many toddler models.

Choose designs with solid sides rather than open rails. A low play house style can double as a den during the day. Check the product page for exact height and mattress depth before ordering. See our range of Shorty Bunk Beds for compact options.

Practical Checklist for Toddlers

  • Maximum top bunk height under 120 cm to floor
  • Staircase access preferred over vertical ladder
  • Guard rails on all open sides of top bunk
  • Gap between top rail and mattress at least 16 cm
  • Base bunk suitable for 70x140 cm toddler mattress

Bunk Beds for School-Age Children (Ages 6-12)

Once children reach age 6, standard bunk beds become suitable. UK bunk beds must meet BS EN 747; the top bunk guard rail requirement remains critical. Wooden bunk beds offer durability and classic looks while metal versions provide a modern industrial feel. Many families choose models with storage to keep bedrooms tidy.

Common UK sizes are small single 75x190 cm (2ft6) or single 90x190 cm (3ft). A staircase design reduces the chance of slips compared with ladders. For rooms with three children, triple bunk beds save floor space but need careful ceiling height checks – allow at least 60 cm clearance above the top mattress.

Teenage and Gaming Bunk Beds (Ages 13+)

Teenagers need more workspace and storage. L-shaped bunk beds or models with integrated desks free up floor area for study or relaxation. Gaming bunk beds often include shelves for monitors and controllers. At this age, king-size lower bunks (150x200 cm) can be requested, though most stay with standard single or small double 120x190 cm (4ft).

Metal bunk beds withstand heavier use and are easier to clean. Look for designs with futons or sofa bases that convert into seating. Always confirm the stated maximum mattress depth to keep guard rails compliant.

Our L-Shaped Bunk Beds and Bunk Beds With Storage suit older children well.

Safety Standards and Measurements

All bunk beds sold in the UK must comply with BS EN 747. The top bunk guard rail must be at least 16 cm above the mattress. Mattresses and upholstered bases must meet the Furniture and Furnishings (Fire) (Safety) Regulations 1988 and BS 7177. Measure your ceiling height before buying: add the bed height, maximum mattress depth and 60 cm clearance.

EU sizes differ – an EU single is 90x200 cm while UK single is 90x190 cm – so check dimensions on each product page. For shared rooms, consider whether a trundle or pull-out extra bed is needed.

Storage and Space-Saving Features

Bunk beds with storage such as drawers, shelves or wardrobes help maximise small bedrooms. Staircase models often incorporate steps with hidden compartments. For younger children, choose rounded edges; for teens, look for desk-integrated options. A children’s bookcase placed nearby can hold bedtime stories or school books.

See the full Kids' Beds selection or Children's Bookcases to complete the room.

Choosing the Right Brand and Finish

Flair offers many practical designs including staircase and playhouse styles that suit multiple ages. Noomi provides FSC-certified wooden options with clean lines. Recoil specialises in gaming configurations popular with teenagers. Solace+Co and Maxitex also appear in our wooden and storage ranges. White, grey and oak finishes are easiest to match with existing bedroom furniture.

Frequently asked questions

What age can a child sleep in the top bunk?

UK guidance states top bunks are not recommended for children under 6. The top guard rail must sit at least 16 cm above the mattress. Always follow the manufacturer’s maximum mattress depth to keep the rail effective. For younger children choose low shorty bunk beds instead.

How much clearance is needed above a bunk bed?

Allow at least 60 cm between the top of the highest mattress and the ceiling. This gives comfortable sitting height and safe movement. Measure your room ceiling first, then check the exact bed height and maximum mattress depth on the product page before purchase.

Are metal bunk beds better than wooden ones?

Metal bunk beds are durable, easy to clean and suit teenagers or gaming setups. Wooden bunk beds feel warmer, often include more integrated storage and suit younger children. Both must meet BS EN 747. Choose according to your room décor and storage needs.

Can you put a double mattress on the bottom bunk?

Many bunk beds accept a small double 120x190 cm (4ft) on the bottom. Check the exact base dimensions on the product page. A standard UK double 135x190 cm (4ft6) rarely fits. Using the correct size keeps the structure stable and guard rails effective.

Do bunk beds with stairs take up more space?

Staircase bunk beds project further into the room than ladder models but the stairs often contain storage drawers, reducing the need for extra chests. They are safer for younger school-age children. Measure your floor area carefully before choosing between staircase and vertical ladder designs.
