How long can you use a travel cot mattress?
Short answer: Typically whenever the travel cot is used for sleep. Always go by the age, weight and development limits in the instructions for your model.
Product limits vary, so check the instructions and the product page.
- Buy only one sized for your travel cot.
- Never stack a second mattress or folded blankets in the travel cot.
- Check it is firm and flat with a waterproof cover.
What the guidance says
- Travel cots need the same safer-sleep set-up as a cot: a rigid frame and base and a firm, flat mattress. Do not add folded blankets or a quilt under the baby.
- Use a firm, flat, waterproof mattress in good condition, with no raised or cushioned edges, that fits the cot or Moses basket with no gaps.
- Mattresses: look for BS 7177:2008+A1:2011, and BS EN 16890:2017+A1:2021 for cot, travel cot and crib mattresses.
