Care Guide
Our waterproof sheets are thoughtfully designed to be durable, practical, and made to handle everyday adventures. To keep them looking and performing their best, please follow the care guidelines below.
Care Guide
- Machine wash cold or warm (below 40°C / 140°F)
- Line dry in the shade or tumble dry on a low setting
- Do not bleach
- Do not iron
- Do not dry clean
- Do not soak
Always check the care label attached to your product before washing.
To maintain the waterproof barrier, avoid exposing your sheet to high temperatures or harsh cleaning products. Excessive heat can damage the waterproof TPU lining, which may cause it to separate from the fabric and reduce its waterproof performance.

Got the Seabreeze Stripe for my little boy’s room and it looks so good. Doesn’t even look like ‘waterproof bedding’ which is exactly what I wanted

I’ve washed ours a few times now and it still feels exactly the same. No weird noise or stiff waterproof layer either.

Had our first proper test last night 🫠 toddler vomit accident at 2am. Mattress completely dry and I only had one thing to change. Whoever came up with this… THANK YOU.
QUESTIONS, ANSWERED
Everything you need to know about NUMI
From waterproofing and washing to sizing and those inevitable 3am accidents.
NUMI brings a fitted sheet and waterproof mattress protection together in one practical layer. Your child sleeps on soft organic cotton, while a hidden waterproof layer beneath helps shield the mattress from wees, spills and everyday accidents. It is a simple mattress protector alternative, so there is no need to put a separate traditional mattress protector underneath.
NUMI waterproof bed sheets have a built-in barrier designed to help protect the mattress from everyday wetness, including wees and spills. The waterproofing also extends down the sides of the fitted sheet for additional mattress coverage. Fit and protection depend on choosing the right size and following the care instructions; no bedding can prevent every leak in every situation.
Waterproof fitted sheets can make nighttime toilet training, bedwetting and unexpected accidents easier to manage, without adding another separate layer to the bed. Try the NUMI two-sheet setup: make the bed with two NUMI sheets before bedtime. If the top sheet gets wet, remove it and there is already a clean waterproof sheet underneath. You'll thank us at 3am.
NUMI was created to remove the need to make the bed with a separate fitted sheet and mattress protector. Waterproof protection is built into the fitted sheet itself, which means one less layer to put on and take off during laundry day.
They are designed to feel like beautiful everyday bedding, rather than a plastic-feeling protector. The sleep surface is soft 300 thread count GOTS-certified organic cotton, paired with a breathable TPU waterproof layer underneath. The result is a comfortable, no-crinkle feel for little sleepers.
NUMI currently offers waterproof cot sheets and waterproof single bed sheets, suited to different stages of toddler bedding and beyond. Before ordering, measure your mattress and check the Size Guide to make sure the fitted sheet is a good match. Browse Cot Sheets or Single Bed Sheets.
Wash below 40°C. Line dry in the shade or tumble dry on low. Do not bleach, soak, dry clean or iron. Following these care instructions helps keep your sheet feeling lovely and its waterproof layer in good condition.
Yes. NUMI waterproof pillowcases are designed to help protect pillows from dribbles, spills, sweat and nighttime mess while still looking and feeling like normal bedding. They make a practical addition to kids bedding in Australia, especially when little ones are still prone to the occasional spill. Explore Waterproof Pillowcases.
With a traditional setup, you fit a mattress protector first and then add a separate sheet. NUMI combines both functions in one layer, so there are fewer layers, easier bed changes and less to manage in the wash. Practical protection also comes with original hand-painted prints, bringing a little personality to the bed.
Every NUMI print begins as original artwork created by founders Billie and Colby on Sydney's Northern Beaches. Their hand-painted designs are made to bring colour and character to children's rooms, pairing thoughtful details with practical bedding for everyday family life.
