Can DockATot be used on top of a waterproof sheet or mattress?
We do not recommend placing a waterproof sheet or mattress underneath DockATot. In fact, we do not ever recommend the use of waterproof materials. All of our materials are breathable, so when placed on top of a non-breathable barrier, such as a waterproof sheet or mattress, there becomes an increased risk of overheating as well as microbial build-up. Overheating is not to be taken lightly, as it has been linked to SIDS.
We have refrained from adding anti-dustmite, anti-fungal and anti-bacterial chemicals to the filling materials, so it is important to keep the dock dry, clean and well ventilated. It’s important to avoid high humidity, dampness, and poorly ventilated parts. Like any piece of bedding, it’s important that both cover and core are 100% dried after washing as well as before use or getting stowed away. It's also important to remove the cardboard that comes underneath the pad before using DockATot.
