Cot Sheets

Waterproof • Sustainable • Beautifully Hand-Painted

Discover cot sheets that finally tick all the boxes — practical for parents, gentle for little ones, and thoughtfully designed with our planet in mind. At Numi, we create waterproof cot sheets that fit seamlessly into your nursery, blending soft comfort with stunning watercolour prints hand-painted by us on Sydney’s Northern Beaches.

Why You’ll Love Our Cot Sheets

🌿 100% Waterproof (Without the Crunch)
Our cot sheets feature a soft, quiet waterproof layer that protects bub’s mattress from spills, leaks, and those unexpected night-time moments — no plastic feel, no rustling sound.

🎨 Hand-Painted Watercolour Prints
Every print begins as a painting. Our signature watercolour designs bring gentle, modern colour to your nursery, inspired by nature, the coast, and the magic of childhood.

💚 Sustainable by Design
As mums, we care about what touches our children’s skin and what ends up in our environment. Our cot sheets are made with durable, eco-conscious materials and designed to last wash after wash.

🤍 Soft, Safe + Skin-Friendly
Crafted with premium fabrics that feel soft and breathable. Safe for sensitive skin and OEKO-TEX friendly (add this if applicable).

🧼 Machine Washable
Easy to clean and quick to dry — because parents have enough on their plate.

A Purchase That Gives Back

For every order, we donate $1 to Kids Under Cover, supporting vulnerable children through health, education, and emergency relief programs. Your cot sheet helps make a difference beyond your nursery.

Perfect Fit for Every Cot

Designed to fit all standard Australian cot mattresses snugly and securely. Stretchy edges make changing the sheet fast and fuss-free.
