Expert buying guide
How to choose a mattress protector
Protect the mattress while preserving its feel by checking coverage, depth, stretch and care.
Confirm mattress depth
Match the protector pocket depth to the mattress height, including any topper, so the corners stay secure.
Balance protection and airflow
Compare membrane construction, fabric, cooling features and washing instructions.
Mattress protector questions
What is the difference between waterproof and water-resistant?
Waterproof protectors are designed with a barrier against liquid penetration. Water-resistant fabrics may slow moisture but do not provide the same level of protection.
What does five-sided mattress protection mean?
A five-sided protector covers the top and four sides of the mattress. A full encasement also covers the bottom and typically closes with a zipper.
How deep should a mattress protector be?
Choose a pocket depth that accommodates the full mattress height plus any topper. A secure fit helps prevent bunching and corner slippage.
How should I wash a mattress protector?
Follow the manufacturer label for water temperature, detergent and drying. High heat can damage some waterproof membranes.
