Frequently asked questions
What depth is considered 'extra deep' for a mattress protector?
Extra deep typically refers to pocket depths of 18 to 24 inches, designed to fit thicker mattresses like pillow-tops or those with added toppers. Always measure your mattress height before purchasing.
Are waterproof mattress protectors noisy?
Modern protectors use thin, noiseless membranes like polyurethane or vinyl-free films that don't crinkle. Look for terms like 'quiet' or 'noiseless' in product descriptions to ensure minimal sound.
Can I wash a mattress encasement?
Yes, most encasements are machine washable. Check the care label; typically, use cold water and tumble dry on low. Avoid bleach and fabric softeners as they can damage the waterproof layer.
Do mattress protectors affect the feel of the bed?
A good protector should have minimal impact on mattress feel. Fitted sheet-style protectors with soft tops, like cotton or bamboo, preserve comfort. Encasements may add slight fabric bulk but are generally unnoticeable.
What certifications should I look for?
OEKO-TEX Standard 100 ensures the fabric is free from harmful substances. CertiPUR-US applies to foam components, but for protectors, OEKO-TEX is more common. Also look for hypoallergenic and waterproof certifications if needed.
