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
A 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.
