HOW EXACTLY DOES IT PROTECT, AND ARE THERE CHEMICALS USED IN THE PROCESS?

There are two layers of knit fabric. In between, we've layered a breathable film (PE) that stops any liquid from reaching the mattress. In order to make a protector that would actually protect, we had to use chemicals — but we intentionally kept them at a minimum. To make the knit impermeable to water we used a PUR adhesive, which is the most effective and safe form of lamination.
