Are travel cots all the same size?
Short answer: No. Travel cot sizes vary by brand, so only use the mattress made for yours, with no extra padding.
Here is the detail behind that answer, taken from current UK guidance from the NHS and the Lullaby Trust.
Things to check
- 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.
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.
