Kids Bed Buying Guide

Choosing the right bed for your child can provide a comfortable, safe and practical place to sleep as they grow.

From toddler beds to single, mid sleeper and bunk beds, this guide explains what to consider when choosing a kids bed, including size, safety, space and longevity.

Choosing the Right Bed for Your Child

Children's beds come in a wide range of sizes and styles, from cot and toddler beds through to single, mid sleeper and high sleeper beds. The right choice will depend on your child's age, size, bedroom space and how long you want the bed to last.

When choosing a new bed, it's worth considering both the bed frame and mattress size. Choosing a larger size where practical can give your child more room to grow and help you get longer use from the bed.

GOOD TO KNOW: Age ranges are only a general guide. Always consider your child's individual development, size and readiness when choosing their next bed.

Types of Kids Beds

Different children's beds are designed for different ages and stages. Here's a quick overview of the most popular options.

Cot & Cot Beds

Designed for babies and younger children, with enclosed sides to provide a secure sleeping environment.

Toddler Beds

Lower to the ground and typically smaller than a standard single, making them a useful transition from a cot.

Single Beds

A popular long-term choice, providing plenty of sleeping space as your child grows.

Mid Sleeper Beds

Raised above the floor to create useful space underneath for storage, play areas or a desk.

High Sleepers

Make greater use of vertical space, often incorporating a desk, storage or play area underneath.

Bunk Beds

A practical option for shared bedrooms, helping provide two sleeping spaces without taking up additional floor space.

What Age Is Each Kids Bed Suitable For?

Every child develops differently, so age ranges should be treated as general guidance rather than strict rules.

0–2 Years

Cots are generally suitable for babies and younger children who still need enclosed sides.

2–4 Years

A toddler or cot bed can provide a suitable transition as your child becomes more independent.

4+ Years

Single and low sleeper beds can provide more room and are suitable for growing children.

6+ Years

Mid sleepers and high sleepers may be suitable for older children, subject to the manufacturer's guidance.

6+ Years · Top Bunk

The top bunk should only be used by children who meet the manufacturer's minimum age recommendation.

SAFETY FIRST: Always follow the manufacturer's recommended minimum age and safety instructions for your chosen bed.

Kids Bed & Mattress Sizes

Choosing the correct mattress size is essential, as children's beds are available in several dimensions that differ from standard adult beds.

Bed Type Approx. Mattress Size General Guide
Cot 60 × 120 cm 0–2 years
Toddler / Cot Bed 70 × 140 cm Approx. 2–4 years
Small Single 2'6" × 6'3" (76 × 190 cm) 4+ years
Single 3' × 6'3" (90 × 190 cm) 4+ years
Small Double 4' × 6'3" (120 × 190 cm) 8+ years

Kids Bed Safety: What Should You Consider?

Safety should always be a priority when choosing a child's bed, particularly when buying raised beds or bunk beds.

Age Recommendations

Follow the manufacturer's minimum age recommendations, particularly for mid sleepers, high sleepers and bunk beds.

Guard Rails

Raised beds should have suitable safety rails designed to help prevent falls during sleep.

Mattress Fit

Make sure the mattress is the correct size and depth for the bed frame, particularly where safety rails are involved.

Room Layout

Position the bed safely and keep windows, cords and other potential hazards away from the sleeping area.

Choosing a Mattress for a Kids Bed

A good children's mattress should provide comfortable, supportive sleep while being the correct size for the bed frame.

Correct Size

Choose a mattress that fits the bed frame correctly, with no unsuitable gaps around the edges.

Support

Look for a supportive mattress that is appropriate for your child's size and sleeping position.

Breathability

A breathable mattress and washable or removable cover can make maintaining a fresh sleeping environment easier.
