Key Takeaways
Mattress protectors cover only the top of the mattress, while encasements completely surround it.
Both options can be waterproof or non-waterproof and protect against spills, allergens, and wear.
Encasements offer greater protection from bed bugs, dust mites, and allergens.
What Is a Mattress Protector?
A mattress protector shields the top surface of your mattress from dust, debris, and moisture. It fits like a fitted sheet with elastic edges and is easy to remove and wash.
Benefits
Protects against spills, sweat, and stains
Helps maintain mattress warranties
Easy to clean and remove
Common Concerns
Heat Retention: Some waterproof protectors can trap body heat. Look for breathable materials like cotton or bamboo blends to stay cool.
Safety for Babies: Waterproof protectors made from polyurethane or wool are considered safe if they lie flat and fit snugly under crib sheets. Avoid vinyl or PVC-based products.
What Is a Mattress Encasement?
A mattress encasement fully encloses the mattress on all sides with a zipper, offering enhanced protection from allergens, bed bugs, and moisture.
Benefits
Comprehensive 360° protection
Blocks allergens, dust mites, and bed bugs
Typically includes a waterproof layer
Common Concerns
Bed Bug Defense: Tightly knit fabric and sealed zippers prevent bed bugs from penetrating or escaping.
Use with Box Springs: Standard mattress encasements are not recommended for box springs. Look for encasements specifically made for box springs with a shallower profile.
