I always encase my mattress in a protector to keep dust, dust mites, etc. from getting into the mattress, to protect it from the rare pet with an upset tummy, and to preserve the life of the mattress. I recently bought a new, major brand, mattress set that has an antibacterial treatment and was unhappy to find it had a slight chemical smell. After zipping the mattress up in this protector, I can barely smell it. The protector had a good vinyl weight, was easy to get on, fit perfectly, and zipped right up. And, importantly, it doesn't make any noise. There is a mattress pad on top of the protector and then the bedding, but I don't think it would make any noise without the extra padding of the mattress pad.
