The standard cot mattress (60 x 120cm) fits most UK cots. What matters most is simple: a firm, flat surface that fits the cot with no gaps.
Why this size?
- 60 x 120cm is the standard UK cot size and fits most cots sold here.
- A correctly sized mattress leaves no gaps around the edges, which is the main safety point with any cot mattress.
- Standard cot sheets are easy to find at almost any price.
- Many cot mattresses have a removable, washable cover, which helps with the inevitable spills.
The mattress must fit the cot snugly with no gaps; standard cot sheets fit.

60 x 120cm, the most common UK cot size. Always check your cot's stated mattress size before buying, as some models differ.
What matters most in a cot mattress?
Fit and firmness. The Lullaby Trust's safe sleep guidance asks for a firm, flat mattress that is waterproof and fits the cot with no gaps around the edges.
Can I reuse a cot mattress for a second child?
Guidance generally recommends a new mattress for each baby where possible. If you do reuse one, it should be clean, firm, flat and free of tears or sagging.
