$59.00

Waterproof Fitted Cot Sheet – 100% Organic Bamboo (White)

Clean, crisp and classic in soft white, our Waterproof Fitted Cot Sheet is both beautiful and brilliantly practical.

Made from luxuriously soft 100% GOTS-certified organic bamboo, it feels just like your favourite fitted sheet, yet secretly protects your baby’s mattress with a discreet waterproof lining underneath.

Say goodbye to juggling layers of protectors and sheets. With this clever two-in-one design, you only have one sheet to change when baby spits up or has a leaky nappy,  because practicality should never compromise style.

Why You’ll Love It

  • Sheet and protector in one – waterproof comfort without the plastic feel
  • Breathable and non-toxic – gentle on delicate skin
  • Sumptuously soft organic bamboo jersey with natural stretch
  • Heat-sealed waterproof lining – silent, durable, and discreet
  • Includes matching waterproof wet bag for easy on-the-go changes
  • Fewer layers = less laundry = more sleep for you

Perfect Fit

Designed to fit most standard cot mattresses (137 × 77 × 19 cm).

Can also be used on oval mattresses of similar size — simply pull the corners down at the back for a snug, secure fit.

What makes the fitted sheets waterproof is the added TPU (thermoplastic polyurethane) layer that is carefully sewn into the underlayer on the bamboo.

The TPU is bonded to 100% organic bamboo fabric via heat and no chemicals are used in this process.

This is what makes the Bamboo and TPU sustainable and biodegradable.
