Toddler Bed Buying Guide UK

Bed Kingdom guide · Updated October 2026 · 3 min read

When your toddler outgrows their cot, choosing the right first bed is an important step. Toddler beds in the UK are typically 70x140cm. This guide explains sizing, essential safety features, mattress choices and decision rules to help you select the best option from our range.

Understanding Toddler Bed Sizes in the UK

UK toddler beds and toddler bed mattresses are commonly 70x140cm, distinct from cot mattresses at 60x120cm and standard single beds at 90x190cm (3ft). This size offers a practical halfway step before moving to a full single bed. Always measure your child's room carefully; allow at least 60cm clearance on each side for easy access and changing bedding. EU sizes differ, so confirm the exact dimensions on the product page before buying.

A good decision rule: if your child is over 18 months and climbing out of the cot, it is time to switch. Toddler beds keep them closer to the floor.

Safety Features to Look For

All bunk beds sold in the UK must meet BS EN 747. For toddler beds the key requirements are low height, secure guard rails on both long sides and no sharp edges. Guard rails should prevent falls without creating entrapment gaps. Check the maximum mattress depth stated by the maker to ensure rails rise at least 16cm above the mattress surface if applicable, though most toddler beds are single level.

UK law requires all mattresses and upholstered furniture to meet the Furniture and Furnishings (Fire) (Safety) Regulations 1988 and BS 7177. Look for labels confirming compliance. Avoid beds with gaps larger than 6cm between slats or rails to prevent head entrapment. A practical checklist includes:

  • Low or floor-level design to reduce fall height
  • Guard rails on both sides that cannot be removed by the child
  • Solid, stable construction with no protruding parts
  • Non-toxic finishes suitable for children
  • Clear assembly instructions and all fixings provided

For added peace of mind, consider Montessori beds which sit directly on the floor, allowing your toddler to get in and out independently.

Choosing the Right Mattress for a Toddler Bed

Pair your toddler bed with a 70x140cm mattress designed for young children. A medium-firm feel supports developing spines without being too hard. Waterproof, anti-allergy covers are practical for this age group. Our toddler mattresses range includes options tested to UK fire safety standards.

Decision rule: choose a mattress depth that fits within the bed's stated maximum to keep guard rails effective. Check the product page for exact specifications. A sprung or foam model from trusted names like Maxitex or Recoil offers good value and durability for daily use.

Toddler Bed Styles and Practical Considerations

Styles range from simple wooden frames to themed designs and Montessori floor beds. Wooden toddler beds are durable and classic, while house-style beds can make the transition exciting. For small rooms, look for designs with minimal footprint.

Consider future use: some toddler beds convert or have storage options. If your child is a restless sleeper, a bed with higher sides or integrated rails is sensible. Always follow the manufacturer's maximum mattress depth to maintain safety. Browse our full toddler beds selection to compare styles side by side.

Parents often combine the new bed with other nursery items. A nursing chair nearby helps with bedtime routines, while changing tables keep essentials organised during the transition phase.

Transition Tips from Cot to Toddler Bed

Make the change gradual. Let your toddler help choose bedding or a nightlight. Keep the bedtime routine consistent. Place the toddler bed in the same position as the cot initially. Use a cot bed if you want longer-term flexibility, as many convert into toddler beds by removing one side.

Practical checklist for the first week:

  1. Explain the new bed in simple terms a few days before
  2. Move favourite toys or a comforter across first
  3. Use a bed guard or floor bed if your child rolls a lot
  4. Install a safety gate at the bedroom door if needed
  5. Check the room for hazards at toddler height

Flair and Solace+Co frames are popular first choices because they combine solid construction with child-friendly designs that suit UK homes.

Frequently asked questions

What age should a child move from a cot to a toddler bed?

Most children move between 18 months and 3 years, usually when they start climbing out of the cot. There is no fixed age; watch for signs of readiness such as attempting to climb. A toddler bed at 70x140cm provides a safe next step with low height and side rails.

Do toddler beds need a special mattress?

Yes, use a 70x140cm toddler mattress rather than a cot size (60x120cm). It should be firm, waterproof and meet UK fire safety regulations. Check the bed manufacturer's stated maximum mattress depth so guard rails remain effective. Options from Maxitex or Recoil work well.

Are Montessori beds suitable for all toddlers?

Montessori floor beds are excellent for independent toddlers from around 18 months as they allow free movement. They sit almost on the floor, reducing fall risk. However, if your child is a very active roller, a model with a safety fence like the Flair Imogen range may be better. Always supervise initially.

Can I use a single mattress in a toddler bed?

No. A standard single mattress is 90x190cm and will not fit a toddler bed frame designed for 70x140cm. Using the wrong size compromises safety rails and stability. Purchase a purpose-made toddler mattress and always verify dimensions on the product page.

How do I know if a toddler bed meets UK safety standards?

Look for BS EN 747 compliance where relevant and fire labels confirming adherence to the 1988 Furniture Regulations and BS 7177. Guard rails must rise sufficiently above the mattress. Reputable brands such as Flair clearly state compliance. Check the maximum mattress depth on each listing.
