If you’ve ever tried to buy bassinet sheets, you’ll know it’s not as straightforward as it should be. There seems to be an endless range of shapes, styles, and sizes - and somehow, none of them seem to match your bassinet at home.
We get it. Bassinet sheets are notoriously hard to buy because, unlike cot mattresses, there’s no standard sizing in Australia. That means finding the right fit can prove difficult if you don't know where to start.
No Standard Size = Endless Guesswork
In Australia, cot mattresses need to follow consistent sizing guidelines, but bassinets don’t. Every brand creates its own shape, depth, and dimensions - oval, rectangular, slimline, deep, shallow and unfortunately, that makes finding the right sheet tricky.
Even products labelled “standard” or “universal” can differ by several centimetres. Too small, and the sheet won’t stretch safely over the corners. Too large, and it risks bunching or coming loose, which can be unsafe for babies.
Why Fit Matters for Safe Sleep
According to Red Nose Australia, a baby’s sleep surface should always be flat, firm, and free from loose bedding or excess fabric. If a bassinet sheet doesn’t fit properly, it can wrinkle, shift, or bunch, which may interfere with safe sleep positioning.
Mattress depth is just as important. Some bassinets have thin or flexible bases that can bow or curve if the sheet is too tight, while thicker mattresses need extra edge depth to ensure a secure hold. Getting that balance right helps keep your baby’s sleep space both safe and comfy.
We know how frustrating the lack of standardisation can be, so we designed a range that covers the most common bassinet shapes and sizes used across Australia.
Our Sizing Range
We’ve designed our waterproof bassinet sheets to fit the most common bassinet shapes and sizes used across Australia.

Perfect for larger European-style bassinets, co-sleepers, and change pads. The deep 12 cm sides and full elastic ensure a snug fit that won’t slip, even on thicker or foam-based mattresses.
Smart Design for Peace of Mind
Every Bambella bassinet sheet features a three-layer waterproof design - a soft cotton top, a thin stabilising polyester core, and a PUL waterproof base. This creates a surface that stays flat and secure while protecting your mattress from leaks and spills.
This creates a firm, flat, and safe sleep surface that protects your bassinet mattress from spills, leaks, and life’s little accidents. They're machine washable, made from OEKO-TEX® STANDARD 100 certified materials and built to last through every wash, bedding change, and 3am feed.
The Bottom Line
Bassinet sheets can be tricky to shop for - but they don’t have to be. Bambella’s three-size range covers the majority of bassinets on the Australian market. Safe, stylish, and oh-so-practical - just the way baby bedding should be.
