What are the Benefits of Mattress Encasements?
Below are some of the benefits of a good mattress encasement. Let’s check them out.- Reduce Stains – A waterproof encasement keeps spills and sweat out of your mattress.
- Protect Against Bed Bugs – A zippered encasement keeps bed bugs from getting into the mattress and traps any already inside, per the EPA.[1]
- Dust Mite Barrier – Allergy groups recommend zippered allergen-barrier covers on the mattress and pillows for people with dust mite allergy.[2]
Buying Considerations for Mattress Encasements
Mattress encasements are available in a variety of sizes. It would be best if you considered the following when buying the mattress encasement:- Mattress Size – Before buying a mattress protector, measure your bed and get the right size for total protection. You don’t want to buy one that doesn’t cover all of it because you won’t be getting full use out of it.
- Comfort – To increase the softness of your mattress or provide additional cushion, choose a protector with thick fabrics like quilted cotton. If you sleep hot, look for a breathable top fabric.
- Features – If you have a dust mite allergy, choose a fully zippered encasement rather than a fitted pad. Top fabrics range from cotton terry to polyester knit and TENCEL.
How often should you Wash Mattress Encasement?
A mattress protector should be washed every two months, depending on usage. Could you consider the following points?- For Guest Bedroom – It’s good to clean the mattress protector in a guest bedroom every quarter. This will keep it looking nice and smelling fresh.
- Allergies – If you have allergies, wash your bedding weekly in hot water; the encasement itself can be washed less often, following the label.[2]
- Illness – If you’ve just recovered from an illness, it is best to clean your mattress protector immediately along with your sheets.
- Spills – If you accidentally spilled some ice cream or coffee in bed, don’t wait for the stain to set. Remove the protector and sheets and wash them following the care label.
