Mattresses, bedding & extras
Cot & cot bed mattresses
Cot mattresses must match the cot exactly: standard cots take 120 × 60cm and cot beds usually 140 × 70cm. Some cribs need their own size. Choose firm, flat and well-fitting.

Prices and availability come from each retailer’s product feed or listing and were last checked 28 September 2026. They can change at any time — the retailer’s site is always the final word. Featured order favours listings with more options and fuller details; it isn’t a quality ranking and no retailer pays for placement.
Before you buy
What to check on any cot mattress
- Measure the inside of the cot or check the maker’s stated mattress size.
- A firm, flat mattress that fits with no gaps is the key safety point.
- Removable, washable covers make accidents easier to deal with.
- The Lullaby Trust’s safer-sleep advice is a good reference for anything a baby sleeps in.
