Quick answer

Choose 120x60cm fitted sheets for standard cot mattresses and 140x70cm sheets for larger cot bed mattresses. The right size ensures a safe, snug fit that reduces suffocation risks.

Why size matters for cot fitted sheets

A fitted sheet that is too loose can bunch up and create a suffocation hazard. A sheet that is too small may not stay in place or could tear. That is why matching the sheet dimensions to your mattress size is a safety priority, not just a comfort preference.

Babylo mattresses come in two common sizes: 120x60cm for standard cots and 140x70cm for cot beds (which convert into toddler beds). The sheets we stock are designed specifically for these dimensions, using deep elasticated corners to hold them securely.

If you are transitioning from a cot to a cot bed, you will need to buy new fitted sheets. Cot bed sheets will not fit a standard cot mattress, and vice versa.

What about multi-packs?

Both sizes are available in multi-packs, which can save you time and money. For the 120x60cm size, you can choose a 4-pack or a 2-pack. For the 140x70cm size, only a 2-pack is available.

A 4-pack is ideal if you are a new parent who wants to minimise laundry loads. A 2-pack is sufficient if you have a backup sheet and do not mind washing more frequently.

Frequently asked questions about cot fitted sheet sizes

Can I use a 140x70cm sheet on a 120x60cm mattress?

No. The sheet will be too loose and can slip off, creating a suffocation risk. Always match the sheet dimensions to the mattress size.

Are all cot fitted sheets the same depth?

Not always. Our sheets are designed with deep elasticated corners to fit standard cot and cot bed mattresses (typically 10-15 cm deep). If your mattress is unusually thick, check the product description for depth compatibility. Measure your mattress depth before ordering if it is thicker than standard.

How many sheets do I really need?

At least two, so you have a spare while one is in the wash. A 4-pack is convenient for newborns who may need multiple changes per night. For older babies who sleep through, a 2-pack is usually enough.

Will these sheets fit other brand mattresses?

Our sheets are specifically designed to be compatible with Babylo mattresses of the same size. They may also fit other brand mattresses of identical dimensions, but we recommend checking the fit carefully before use. Test the sheet on your mattress before putting your baby down. It should be snug with no excess fabric.
