This innovative lining is free from PVC, phthalates, and harmful chemicals, making it a safe, eco-friendly choice for sensitive skin. With its ultra-thin yet durable construction, it blocks moisture from spills, nappy leaks, and overnight accidents while maintaining the cosy softness of organic cotton on top.
Made from ultra-soft, breathable organic cotton, these cot sheets help regulate temperature and protect delicate skin—making them the perfect choice for newborns and toddlers.

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.

- MVMonica V.15 minutes agoReviewingLemonade Days Waterproof Cot SheetRated 5 out of 5 starsWhere were these two years ago?!
My youngest is a shocking bed wetter and changing a protector AND sheet in the middle of the night was the worst. This just makes sense.
- TTahlia16 minutes agoReviewingLemonade Days Waterproof Cot SheetRated 5 out of 5 starsFive stars from us
Washed ours a few times now and they’ve come out perfectly every time. Still soft, still waterproof and the print hasn’t faded. Really impressed with the quality.
- TQTaylor Q.YesterdayReviewingLemonade Days Waterproof Cot SheetRated 5 out of 5 starsIt actually works
Was sceptical that a fitted sheet could actually be waterproof but can confirm it works. Our son had an accident and the mattress underneath was completely dry. Very impressed.
- AAmandaVerified Reviewer3 weeks agoReviewingLemonade Days Waterproof Cot SheetRated 5 out of 5 starsCan't believe how soft these are
I was really surprised at just how SOFT these sheets are. And I can attest to the fact that they do not feel waterproof at all. I bought one for my daughter and will absolutely be purchasing another. LOVE!
QUESTIONS, ANSWERED
Everything you need to know about NUMI
From waterproofing and washing to sizing and those inevitable 3am accidents.
NUMI combines a fitted sheet and waterproof mattress protection into one practical layer. Your child sleeps on soft organic cotton, while a hidden waterproof layer underneath helps protect the mattress from wees, spills and everyday accidents. It is a simple mattress protector alternative, so you do not need to put a separate traditional protector underneath.
NUMI waterproof bed sheets have a waterproof layer designed to help keep moisture from reaching the mattress during everyday use. The protection extends down the sides of the fitted sheet for extra mattress coverage. As with any bedding, correct sizing and a snug fit matter; follow the care instructions to maintain the fabric and waterproof layer over time.
Waterproof fitted sheets can make nighttime toilet training and bedwetting feel more manageable, with less laundry and a quicker bed change after an unexpected accident. Try NUMI’s two-sheet setup: layer two NUMI sheets before bed. If the top sheet gets wet, take it off and there is already a clean waterproof sheet underneath. You'll thank us at 3am.
NUMI was specifically created to remove the need for a separate fitted sheet and mattress protector. Waterproof protection is built into the sheet itself, giving you one practical layer to make the bed with. This streamlined setup is useful for busy family bedrooms and middle-of-the-night changes.
They are designed to feel like beautiful everyday bedding, rather than a traditional plastic-feeling waterproof protector. The top is soft, 300 thread count GOTS-certified organic cotton, paired with a breathable TPU waterproof layer beneath. The result is a comfortable, no-crinkle feel for sleep and rest.
NUMI currently offers Cot and Single waterproof fitted sheets, including waterproof cot sheets and waterproof single bed sheets. Before ordering, measure your mattress and compare it with the Size Guide to check the best fit for your bed and mattress depth. Explore 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 look after both the cotton and waterproof layer.
Yes. NUMI waterproof pillowcases help protect pillows from dribbles, spills, sweat and nighttime mess while still looking and feeling like normal bedding. They are an easy addition to toddler bedding and family beds alike. Browse the Waterproof Pillowcases collection.
NUMI’s two-in-one design combines the waterproof mattress protection and fitted sheet in a single layer. Instead of making the bed with a protector and then another sheet over the top, you use one. That means fewer layers, simpler laundry and easier bed changes, finished with NUMI’s original hand-painted prints.
Every NUMI print begins as original artwork created by founders Billie and Colby on Sydney's Northern Beaches. Their hand-painted designs bring a thoughtful, playful touch to practical kids bedding in Australia, so bedtime essentials feel special as well as useful.
