Compare the 66 x 28 x 3 cm and 74 x 28 x 3 cm Moses Basket Mattresses, learn how to measure your basket, and pick the replacement that fits without gaps.
Quick answer
Measure the inside length of your Moses basket at its longest point: choose the 74 x 28 x 3 cm mattress for baskets that need roughly 74 cm of length, and the 66 x 28 x 3 cm mattress for standard baskets closer to 66 cm. Both share the same 28 cm width and 3 cm depth, so length is the deciding measurement.
Why the length measurement decides the fit
The two mattresses differ only in length: 66 cm versus 74 cm. Width (28 cm) and depth (3 cm) are identical, so the basket's internal length is the one dimension that separates a snug fit from a loose one. A mattress that is too short leaves a gap at the ends where a newborn could roll or become wedged; one that is too long will buckle and lift at the edges instead of lying flat.
Because both options use the same breathable, anti-allergenic cover and nursery-grade poly fibre insert, you are not trading comfort or materials for size. The choice is purely about matching your basket.
When the 74 x 28 x 3 cm mattress is the better trade-off
The larger mattress suits baskets described as larger or longer than standard. The trade-off is that it will not compress into a 66 cm basket, so it is only the right buy if your measurement genuinely lands near 74 cm. If your basket sits between the two sizes, do not assume the bigger one will settle in; a mattress that does not lie flat is a poor base for sleep.
When the 66 x 28 x 3 cm mattress is the safer choice
This is the size to start with for most standard Moses baskets. Its trade-off is less length for larger or unusually long baskets, where it would leave end gaps. If you are replacing a mattress and the old one was labelled 66 x 28 cm, matching that label is the simplest route, provided your basket has not changed.
Trade-offs and how to measure before you buy
- Measure the internal length, not the outside: Run a tape measure along the inside of the basket from the innermost point at one end to the innermost point at the other, at the level where the mattress will sit. Do not measure the basket's outer shell or handles. Write the number down and compare it with 66 cm and 74 cm before ordering.
- Check the width and depth too: Both mattresses are 28 cm wide and 3 cm deep. If your basket's internal width is noticeably more or less than 28 cm, neither option will fit well, and you should look for a different size rather than forcing one of these. A correct length with the wrong width still leaves gaps.
- Replace when the cover or insert is worn: A replacement mattress restores a flat, breathable sleep surface. If your current mattress sags, has a compressed insert, or the cover no longer stays clean, replace it rather than adding folded blankets underneath. Never pad a too-small mattress to make it fit; buy the correct size instead.
