They look and feel a just like regular sheet, while underneath they have a discrete waterproof lining.
✔ 100% Waterproof
✔ Organic Bamboo
✔ Easy Care
Clean, crisp and classic in a soft white, our Waterproof Fitted Cot Sheet is your aesthetically pleasing sheet and waterproof mattress protector in one.
Made from luxuriously soft 100% GOTS‑certified organic bamboo, this breathable and non‑toxic sheet looks and feels just like a regular fitted sheet, but with a clever, discreet waterproof lining underneath.
Say goodbye to juggling layers of protectors and sheets. When baby spits up or there's a leaky nappy, you’ve only got one sheet to change, because practicality should never compromise style.
Designed to make your life easier (especially during those 2 a.m. changes), this two‑in‑one solution keeps your baby’s mattress fresh, dry and protected night after night.
The minimalist white colour blends seamlessly with any nursery theme, while the snug fitted design ensures a safe, secure sleep surface.
Size: 137 × 77 × 19 cm Fits most standard cot mattresses
Oval Mattresses:
Our sheets are rectangular in shape. You can use them on an oval shaped mattress with the same width and length dimensions by pulling the corners down at the back. Check out our socials for fit demo's.
Features:
Waterproof fitted cot sheet = sheet + protector in one
Sumptuously soft organic bamboo jersey outer with natural stretch
Discreet, heat‑sealed waterproof lining
Breathable, non‑toxic, and gentle on delicate skin
Made from 100% GOTS‑certified organic bamboo
Includes matching waterproof wet bag
Fewer layers, less laundry, more convenience
Effortless to use, easy to love, this is the cot sheet every modern parent needs.
What makes the fitted sheets waterproof is the added TPU (thermoplastic polyurethane) layer that is carefully sewn into the underlayer on the bamboo.
The TPU is bonded to 100% organic bamboo fabric via heat and no chemicals are used in this process.
This is what makes the Bamboo and TPU sustainable and biodegradable.

Frequently Asked Questions:
What makes our fitted sheets waterproof?
We've designed these sheets with love by bonding soft bamboo to a durable waterproof layer. This means your little one sleeps on a surface that's both cosy and protective.
Our thermal bonding process ensures waterproofing covers the entire sheet without harsh chemicals, making it a safer, eco-friendly choice that doesn’t compromise on quality.
Enjoy peace of mind knowing spills and accidents won’t seep through, keeping mattresses dry and fresh, while still providing a soft, comfy surface for your child to rest on
How do I wash them?
The Zoe Sage waterproof sheet range is designed with easy care in mind. Simply toss them in the washing machine on a gentle cycle, up to 40°C.
For the best results, we recommend line drying in the shade, but if you’re in a hurry, pop them in the dryer on a low setting.
Are they noisy to sleep on?
Our waterproof bedding stands out because we skip the usual plastic or PVC materials. Instead, we use a soft TPU waterproof lining, ensuring your little one enjoys a peaceful, rustle-free sleep.
With our waterproof cot sheets, you don’t have to choose between comfort and protection—you get both!
The TPU lining keeps mattresses dry and fresh while maintaining the softness your child deserves, making bedtime cosy and stress-free for everyone.
Will these fit my baby's cot?
Our waterproof sheets are designed to fit most Australian cot sizes, which tend to be more standardised than bassinets or other baby bedding.
You can rest easy knowing our sheets will snugly fit your cot, providing reliable protection and cosy comfort for your little one.
Is the sheet safe for newborns?
Yes! The sheet is made from 100% certified organic bamboo, making it naturally hypoallergenic, breathable, and gentle on newborn skin.
Why is a waterproof sheet useful?
It simplifies your bedding setup—no more layered mattress protectors. It saves time, laundry, and stress, especially during those 2 a.m. changes..
What’s included in the purchase?
Each set includes one waterproof fitted cot sheet and a matching waterproof wet bag for convenient storage or travel.
Is this sheet breathable even with the waterproof layer?
Absolutely. The organic bamboo fabric is naturally breathable, and the waterproof layer is designed to maintain airflow while protecting against leaks.
Do I still need to use a mattress protector?
That’s the beauty of our waterproof sheet range—it’s a 2-in-1 solution! With our sheets, there’s no need for separate mattress protectors and sheets—it’s all rolled into one convenient package.
Just pop our waterproof sheet onto the cot, and you’re good to go—no extra fuss required.
