Frequently Asked Questions (FAQs)
1. Can bed bugs bite through mattress encasements?
As we've discussed, mattress encasements don't have any gaps large enough for bed bugs to fit through. Once they're inside, they're trapped. Because they don't have teeth, they can't chew holes in the encasement. And their proboscises can't penetrate the fabric, so they can't bite you while they're inside.
2. Is cotton good for mattress protector?
Cotton mattress protectors are often the most expensive, especially if quilted with a soft cotton filling. Cotton is breathable and a good temperature regulator, making it a smart choice if you get hot at night.
3. Is a cotton or wool mattress protector better?
It's also worth noting that pure synthetic protectors will not be as durable or long-lasting as cotton. Wool - If you're looking for firm but comfortable support then wool is a good choice.
4. Is cotton or polyester mattress protector better?
Cotton – naturally better. Its natural structure enables it to breathe better than synthetic fibres. This is why it's more comfortable to sleep in than polyester and acrylics, which really are the equivalent of sleeping on plastics.
