Not yet tested, but I know the product is perfect because I have it in other sizes. It protects the mattress perfectly from night-time leaks or spilt water bottles, while keeping the child completely cool :)

I know this product because it has already been tested and approved, hence the new order. The undersheets are very effective and comfortable

Thin and light. Very good quality. Would recommend!

Waterproof without plastic noise, envelops mattress well

Perfect and soft
