Are all Moses baskets the same size?
Short answer: No. Sizes vary by brand, so use the mattress and sheets made for your basket, or measure carefully. The mattress must fit with no gaps.
Here is the detail behind that answer, taken from current UK guidance from the NHS and the Lullaby Trust.
Things to check
- Use the mattress made for that basket, so it fits with no gaps.
- Use the basket on the floor or on its own stand, never on a raised surface like a sofa or table.
- Check the weight limit in the instructions.
What the guidance says
- 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.
- Moses baskets and carrycots: look for BS EN 1466:2014 or BS EN 1466:2023.
