Size guide
Measuring your cot
A few careful measurements help the Napper team confirm which size suits your cot. We don’t confirm fit online: every size, standard or custom, is checked with you first.
- 1
Measure the inside length
Measure along the base of the cot, from the inside of one end to the inside of the other. Measure at the base, not the top rail.
- 2
Measure the inside width
Measure across the base, from the inside of one side to the inside of the other.
- 3
Measure the depth
Measure from the base up to the top of the side rail. This helps Napper check the thickness that suits your cot.
- 4
Check in a few places
Cots aren’t always perfectly square. Measure each side twice and note the smallest number.
- 5
Ask us to confirm the fit
Send the measurements and how you’ll use the mattress. The Napper team will confirm the fit with you before anything is supplied or made.
Record your measurements
We’ll show them in both units and add them to a fit-confirmation request.
Required, so Napper can confirm both the fit and that the product suits how you’ll use it.
Listed standard sizes, for reference:
- Napper Premium 4″: 28″ × 48″ (standard crib)
- Napper Premium Cradle 6″: 28″ × 48″ (standard crib)
A close number isn’t a confirmed fit. Napper will check your measurements with you.
