Parent fitting a waterproof bamboo cot sheet

Are they safe?

Yes, when they fit firmly like a standard fitted sheet. Use a firm mattress with a fitted sheet only.

How do they work?

A soft outer layer bonded to a quiet, breathable waterproof membrane to block leaks without plastic crinkle.

Will it feel like a normal sheet?

Yes. The soft bamboo surface feels like a regular fitted sheet; the waterproof layer sits quietly underneath so there’s no “plastic” feel.

Who are they for?

Newborns to toddlers, daycare spares and travel, any time quick, hygienic changes help.

FAQs

Do I still need a separate protector under a waterproof fitted sheet?
Usually no. The built-in membrane protects the mattress so you can change just one sheet after leaks. If you prefer double protection for heavy leakers, you can layer a spare sheet on top for fast swaps.
Will a waterproof sheet make my baby hot?
Quality membranes are breathable and quiet. Dress for the room temperature using a TOG guide and avoid heavy layers.
How many sheets do I need?
Most families find 2–3 sheets per sleep surface works: one on the cot, one in the wash, one spare for night changes or daycare.
How do I wash waterproof bamboo sheets?
Cold or warm gentle cycle. Mild detergent. No bleach or fabric softener. Line dry or low tumble if allowed by the care label.
Good for eczema or sensitive skin?
The smooth bamboo surface is gentle and non-irritating, designed for delicate skin.
Does it bunch or slip?
The snug fitted design grips securely around the mattress corners for a firm, safe fit.
Is it noisy or crinkly?
Nope. The bonded membrane is quiet, so movement won’t rustle or wake a light sleeper.
