Waterproof Fitted Sheets for Bassinet, Cot and Toddler Beds

Leaks happen. Reflux, nappy blowouts, sippy cup spills, fevers. Our waterproof fitted sheets sit on top of the mattress like a normal fitted sheet, except they keep everything underneath bone dry. Made from soft organic bamboo with a hidden waterproof layer. No noisy plastic, no crinkly feel, no swap-out routine in the middle of the night.

Why Mums Choose Our Waterproof Sheets

• GOTS-certified organic bamboo verified farm to finished product, not just "organic" on a label.
• OEKO-TEX Standard 100 waterproof layer independently tested for harmful substances. No PVC, no phthalates, no PFAS, no BPA.
• Quiet, breathable bamboo nothing like the crinkly plastic protectors. Soft on the skin, gentle in summer.
• Sized for every bed bassinet, cot, change pad, and toddler bed sizing so the same sheet logic carries through every age.
• Genuinely waterproof blocks every kind of leak you can imagine. Holds up overnight, every night.
• Heat-sealed, not glued waterproofing that survives the wash cycle, run after run.
• Machine washable tumble dry low and back on the bed in under an hour.
• Doubles as your top sheet use on its own or layer over your usual fitted sheet. One layer to swap at 2am, not two.

The Best Waterproof Sheet for a Bassinet

Newborn nights are the leakiest. Our waterproof bassinet sheet doubles as a change pad cover, so when bub outgrows the bassinet at 3 to 4 months, the sheet keeps earning its keep on the change table. One sheet, two jobs, less in landfill.

Toddler Waterproof Sheets for Potty-Training Years

Toilet training and night accidents go hand in hand. A waterproof fitted sheet on the cot or toddler bed means a 2am accident is a quick sheet change, not a midnight mattress wash. Our cot size fits standard Australian cots and converter beds.

How They Compare to Mattress Protectors

A traditional mattress protector goes underneath your fitted sheet, which means two things to wash and re-make at 2am. Our waterproof sheet IS the fitted sheet. Faster swap, fewer layers, calmer night. Read the full breakdown: Waterproof Cot Sheet vs Mattress Protector: What's Best for Your Baby?
