Our Materials - GOTS Organic Cotton & TPU

Our Materials

Organic cotton, organic bamboo, and a non-toxic waterproof layer. Nothing nasty in between.

Oeko-Tex certified

100% Organic Cotton

Non-toxic, phthalate-free

No chemical processing

Three layers. One sheet.

Most waterproof bedding is two products: a fitted sheet, and a plastic protector underneath it. Ours is one.

Using heat, we bond our TPU waterproof layer to 100% organic bamboo, then sew that into a 100% organic cotton fitted sheet. What you get is a single soft, breathable, protective surface - organic cotton against your child's skin, waterproofing hidden inside, and a mattress that stays dry.

One layer instead of two. Less laundry, less bulk, and no plastic sheet crinkling underneath at 2am.

✓ Replaces the sheet and the mattress protector

✓ No PUL, no crinkle, no compromise

✓ Breathable backing that actually works

100% Organic Cotton

The face of every sheet - the surface your child actually sleeps against. We use only the highest quality 100% certified organic cotton, with no shortcuts on the bit that matters most.

The result? Beautifully soft, breathable, planet-friendly cotton that's gentle on even the most sensitive skin. It's the same cotton we'd want against our own children, which is the only standard we design to.

✓ Certified organic, highest quality

✓ Breathable and planet-friendly

✓ Safe for sensitive skin

100% Organic Bamboo

We chose bamboo for our waterproof layer (alongside the TPU) because it's genuinely super soft and seriously durable. It can be washed time and time again while holding onto its original quality, shape and snuggliness.

Bamboo is also naturally antimicrobial - meaning it helps protect your child's skin against harmful substances. Clever, huh? The bamboo we source is grown and harvested with no nasties, no chemicals are used in manufacturing, and it's Oeko-Tex certified.

Why TPU Is Better

We use TPU (Thermoplastic Polyurethane) as the waterproof layer in our fitted sheets because it offers the perfect balance between performance and sustainability. It lasts longer, reduces waste over time, and can be recycled or repurposed - helping lower its overall environmental footprint.

	Our TPU Layer	Traditional plastics (e.g. PVC)
Non-toxic	Yes	No
Free from phthalates	Yes	Contains harmful chemicals
Durability	Highly durable - lasts longer, less waste	Degrades sooner

The Finer Detail

For the parents who want to know exactly what they're buying.

Is TPU biodegradable?

We'd rather be straight with you than overclaim. Most TPU isn't classified as biodegradable in everyday conditions. However, research shows certain types can be broken down by microorganisms in specific, controlled environments - which makes it a more progressive, planet-conscious option than conventional plastics, but not a compostable one. We're honest about that, and we keep exploring better.

Is it really safe against my child's skin?

Yes. TPU is 100% waterproof, flexible, and safe for skin contact - and in any case it never touches your child, because it sits beneath the organic cotton face of the sheet. It's free from harmful chemicals like phthalates, and our bamboo is Oeko-Tex certified.

What are you doing about sustainability?

Sustainability isn't a buzzword for us, it's a core value that guides every decision we make. We source materials certified by recognised standards, so every thread meets stringent environmental and social criteria - which means choosing our sheets supports fair trade and the communities behind them. We're also investing in innovation, including recycled fibres, to keep lowering our footprint.

How do I care for my sheets?

They're built to be washed, again and again - that's the entire point of a sheet that lives under a small child. Full washing and drying guidance is in our Care Guide.
