Frequently asked questions
What is a fully encased mattress protector?
A fully encased mattress protector zips around the entire mattress, covering all six sides. Unlike fitted sheets, it seals completely to protect against bed bugs, dust mites, allergens, and spills.
Do fully encased protectors make you hot?
Not necessarily. Many modern protectors use breathable materials like cotton, bamboo, or stretch knit with waterproof membranes that allow airflow. Avoid vinyl or plastic-based options if you sleep hot.
Can you wash a fully encased mattress protector?
Yes, most are machine washable. Always check care instructions – typically wash in cold, gentle cycle and tumble dry low. Avoid bleach and fabric softeners to preserve the waterproof layer.
How do I know if it fits my mattress?
Check the depth rating – most protectors fit mattresses up to 12-18 inches thick. Measure your mattress height and compare. Some protectors are designed for specific depths.
Are bed bug proof encasements worth it?
Yes, if you travel frequently or live in multi-unit housing. A fully encased protector with a secure zipper, like those with bed bug certifications, can prevent infestations and save costly mattress replacement.
