Waterproof Cot Sheets & Protectors

Award winning practical mum and baby essentials

Baby sheets waterproof enough to handle reflux, nappy blowouts and middle-of-the-night leaks. Soft on skin, silent in use, easy to strip and wash.

Fitted Waterproof Sheets for Bassinet and Cot

These sheets go on just like a regular fitted sheet. No bulky mattress protector underneath. No noisy plastic layer rustling every time your baby moves. A hidden waterproof barrier keeps the mattress completely dry, while the top layer stays soft and breathable against your baby's skin.

Bamboo Bassinet Sheets With a Waterproof Layer

Bamboo viscose is soft, breathable and gentle on newborn skin. Our waterproof sheets pair a bamboo viscose jersey top with a silent TPU lining, so your baby sleeps against soft fabric, never plastic.

Why Two Sheets on the Bed Makes Sense

Layer two waterproof fitted sheets on the cot at bedtime. When a leak happens at 2am, pull the top sheet off and the clean one is already in place underneath. No hunting for fresh linen in the dark. No full bed remake. Back to sleep in under a minute.

Your Waterproof Cot Sheet Questions Answered

What makes these waterproof sheets different from regular mattress protectors?

Our waterproof cot sheets combine a fitted sheet and mattress protector in one, so there's no need for extra layers on the cot. The waterproof membrane is built right into the soft bamboo viscose fabric, meaning no noisy, crinkly plastic between your baby and a good night's sleep. They feel just like a beautifully soft fitted sheet while keeping the mattress fully protected underneath.

Are the waterproof sheets safe for newborns and sensitive skin?

Absolutely. Our sheets are made from bamboo viscose, which is soft and gentle on delicate newborn skin, with a breathable waterproof layer that protects the mattress without compromising on comfort. They're perfect for bubs from day one.

Will the waterproof layer make the sheet noisy or hot?

Not at all! Unlike traditional plastic-backed protectors, our built-in waterproof membrane is virtually silent and won't disturb your baby's sleep. Bamboo viscose is also breathable and temperature-regulating, helping to keep your little one cool in summer and cosy in winter. It's all the protection without any of the crinkle.

What sizes are available and will they fit my cot or bassinet?

We offer waterproof fitted sheets to suit standard Australian cot mattresses as well as a versatile bassinet sheet that doubles as a change pad cover. Each sheet features a snug elastic edge designed to fit securely around the mattress without bunching or shifting. Please check the individual product listings for exact dimensions to ensure the best fit for your specific mattress.

For tips on getting a snug, safe fit around your mattress, see our Cot Sheet Fit Guide.

How do I wash and care for waterproof bamboo sheets?

Caring for them is easy — simply machine wash on a gentle cycle in cold or warm water and tumble dry on low heat or line dry. Avoid using bleach or fabric softeners, as these can break down the bamboo fibres and waterproof membrane over time. With proper care, your sheets will stay soft, effective and looking beautiful wash after wash.

For the full method, read our step by step guide to washing waterproof bamboo cot sheets.

Do I need a separate mattress protector underneath these sheets?

Nope, that's the beauty of these sheets! The waterproof layer is already integrated into the fitted sheet itself, so you can skip the extra mattress protector entirely. This means fewer layers to fuss with during those middle-of-the-night changes and a cleaner, simpler setup in the cot. One sheet does the job of two.

Do these waterproof sheets make a good baby shower gift?

They really do — they're one of those practical gifts that new parents genuinely appreciate but might not think to buy themselves. Beautifully soft, stylish and incredibly useful, they tick all the boxes for a thoughtful and functional present. Pair one with a matching bassinet sheet or another Zoe Sage essential for a gorgeous gift bundle any new parent would love.
