What Is a Toddler Bed? Is a Toddler Bed the Same as a Single Bed?

by Emma Whitlow

Your little one is growing fast — and before you know it, it’s time to say goodbye to the cot! But what comes next: a toddler bed or a single bed? Many parents wonder whether they’re the same thing or if it’s worth investing in a smaller, transitional bed first.

In this article, we’ll explain exactly what a toddler bed is, how it differs from a single bed, and how to decide which option is right for your child.

What Is a Toddler Bed?

A toddler bed is a small, child-sized bed designed as the next step after a cot and before a standard single bed.

It gives your child the freedom to climb in and out on their own — helping them build independence while still providing the safety and comfort they’re used to.

Most toddler beds in the UK share these features:

  • Low height (close to the ground for safety)

  • Side rails or guards to prevent rolling out

  • Compact size — fits a standard cot mattress (140 x 70 cm)

  • Sturdy wooden frame that supports active little sleepers

Toddler Bed vs Single Bed: What’s the Difference?

Although both serve the same purpose: Giving your child a safe, cosy place to sleep, but they’re not the same in size or design.

Here’s a clear comparison:

Feature Toddler Bed Single Bed
Standard Size (UK) 140 cm x 70 cm 190 cm x 90 cm
Age Range 18 months – 6 years 6 years and up
Height Low to the ground Higher off the floor
Safety Rails Often included or optional Rarely included
Mattress Cot mattress size Single mattress
Purpose Transitional, promotes independence Long-term sleeping solution

 

When Should You Move Your Child to a Toddler Bed?

Most children move from a cot to a toddler bed between 18 months and 3 years old — once they start climbing out of the cot or showing signs of independence.

Here are a few indicators your little one is ready:

  • They can climb in/out of their cot safely

  • They’ve started potty training and need easy access at night

  • They’re becoming more independent at bedtime

Making this transition with a toddler bed keeps bedtime familiar and safe, while giving them a “grown-up” feeling.

Montessori Toddler Beds: A Growing Trend

In recent years, Montessori-style toddler beds have become popular among UK parents.

These are floor beds or low rise beds that let children explore their room freely and independently — aligning with Montessori principles of self-sufficiency.

Snuglee’s solid pine Montessori-inspired beds combine beautiful design with safety and practicality, creating a space that feels both fun and empowering for your child.

When to Upgrade from a Toddler Bed to a Single Bed

Most children outgrow their toddler bed by 5 or 6 years old, depending on height and comfort.

You’ll know it’s time to upgrade when:

  • Your child’s feet start touching the frame or footboard

  • They ask for “a big bed”

  • You’re redecorating or rearranging their room for school age

Transitioning from a toddler bed to a single bed is much easier than from a cot — your child will already be used to sleeping independently.

Final Thoughts

toddler bed is more than just a piece of furniture — it’s your child’s first real step toward independence. Choosing the right one ensures they feel safe, confident, and comfortable every night.
