What mattress does a travel cot need?
Short answer: 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. Use the size your frame lists.
- Use only the mattress made for that travel cot. Never add folded blankets or a quilt underneath.
- Practise putting it up and folding it before you travel.
- Check the weight and height limits.
