A cot bed is the British term for a crib—an enclosed bed for babies and toddlers, often convertible into a toddler bed.
If you keep seeing “cot bed” on UK-based baby furniture sites, you’re looking at a crib. Cot bed is the standard British English term for what Americans call a crib. The confusion cuts both ways, since “cot” in the US usually means a lightweight foldable camp bed for adults, not a baby’s sleeping space.
What Exactly Does “Cot Bed” Mean?
In the UK, Ireland, and other Commonwealth countries, a cot bed is a small bed with high sides designed to keep a baby safely enclosed while sleeping. The word “cot” comes from the Hindi word khāt, meaning a light bedstead or couch, and Merriam-Webster confirms the term traveled through British colonial usage. The Cambridge Dictionary defines a cot simply as “a small bed for a baby or young child with high bars around the sides.”
Here’s where it gets useful for American shoppers: some cot beds are convertible. “Cot bed” in retail listings often means the piece functions as a crib first, then converts into a toddler bed as the child grows—the key distinction from a standard fixed crib.
A smaller 120 × 60 cm format exists for mini cot beds, though the larger size is far more common—and more practical since it carries the child longer.
How Does a Cot Bed Differ From a Crib?
In practical terms, almost nothing separates a cot bed from a US crib. Both are enclosed sleeping spaces with slatted sides, meet similar safety expectations, and are sized for infants and toddlers. The real differences are naming and conversion.
- Cot bed (UK): Typically 140 × 70 cm; often converts from crib to toddler bed.
Retailers like CuddleCo state their cot beds are compatible with 140 × 70 cm cot bed mattresses specifically—so check dimensions before buying, and never improvise a mattress fit.
Cot Bed Safety and Usage Guidelines
Safe-sleep guidance is consistent across countries. New Zealand’s product safety authority advises placing babies to sleep on their backs from birth—not on their tummies or sides. The same source warns that newer standards govern infant sleep products and inclined non-sleep products, meaning cot beds sold today must meet stricter design requirements than older models.
When using a cot bed, keep the mattress firm and flat, avoid loose bedding, and stop using the cot bed at the convertible stage only when the child can climb out or has reached the manufacturer’s height or weight limits.
Not every cot bed converts to a toddler bed; conversion is model-specific, so read the listing carefully. Some models like the Little Acorns Athena Convertible Mini Day Cotbed convert explicitly, while others are fixed cribs with a different name. If the convertible feature matters to you, confirm it before purchasing.

Common Cot Bed Sizes and What to Check Before Buying
Before ordering a cot bed—especially from an overseas retailer—verify which format you’re getting. The two standard configurations are 70 × 140 cm and 60 × 120 cm, and mattress compatibility depends entirely on the bed frame you choose.
One retailer dimension example shows a cot bed measuring 74 cm × 144 cm × 83 cm overall, giving a sense of the furniture’s full footprint. Name brands currently on the market include Babymore, CuddleCo, Obaby, and John Lewis’s Wilton line—each with different conversion features.
For American buyers, the practical takeaway: if you see “cot bed” in a listing or review, translate it as “crib” and check whether it converts. The term isn’t standard in the US, so asking the retailer directly is always safer than assuming.
FAQs
Is a cot bed the same as a crib?
Yes. Cot bed is the British English term for what Americans call a crib. Both describe an enclosed bed with tall sides for babies and young children, and both are designed for safe, supervised sleep during the first few years of life.
What size mattress fits a standard cot bed?
Most full-size cot beds take a 140 × 70 cm mattress, while mini cot beds use a 120 × 60 cm size. Always check the manufacturer’s compatibility notes, since a poorly matched mattress creates dangerous gaps in a baby’s sleep space.
Can a cot bed convert into a toddler bed?
Only some models convert. Convertible cot beds transform from a crib into a toddler bed with lower or removable sides as the child grows. Fixed cot beds do not convert, so confirm the feature before buying if you want the extended use.
