A mattress protector, pad, or encasement helps protect your mattress and prolong its lifespan. These covers help keep spills, sweat and dust out of your mattress. The Mattress encasement is similar to a mattress protector, with the difference that it fully encases your mattress and completely closes rather than just covering the top area of the mattress.

What is the Difference Between a Mattress Encasement, Pad and Protector

Mattress encasements, pads, and protectors come in various sizes to fit standard, double, queen, and king-sized mattresses. They are usually waterproof and machine washable and aim to protect and enhance your mattress. While a Mattress pad provides an extra layer of cushioning and protection, a mattress protector wraps the mattress for protection. The Mattress encasement, however, completely encases your mattress from top to bottom, with zip closure, so the whole mattress is covered. There are, in turn, a few types of mattress encasements available; Types of Mattress Encasements;

• Allergy Protection Mattress Encasement – For people with dust mite allergy, allergy groups recommend zippered allergen-barrier covers on the mattress and pillows.^[1] They also protect against pet dander and pollen that can cause allergies and build up inside your mattress. Washing bedding weekly in hot water also helps control dust mites.^[1]
• Bed Bug Protection Mattress Encasement – A bed bug encasement keeps bed bugs from getting into the mattress and traps any already inside. It doesn’t treat an infestation elsewhere in the room.^[2]

When Would You Need a Mattress Encasement?

When you need something that provides complete protection against wetness and spills in your mattress, an encasement is a much better choice than mattress protection. A zippered encasement also keeps dust mite allergens sealed inside the mattress.^[1] A bed-bug-rated encasement keeps bed bugs out of the mattress. If allergy symptoms bother you at night, an encasement is one step to try. See a doctor if symptoms continue. The Mattress encasement can be washed regularly while your mattress stays clean and fresh. The mattress encasement is also ideal for children and elderly individuals who may have an “accident” at night, as it protects the mattress from spills.

Features of a Good Mattress Encasement

• Use -You get various mattress encasements and must choose one according to its ultimate purpose. Some are waterproof for protection against liquids and spills, while others are for protection against allergens and bed bugs. Mattress encasements are generally ideal if you have sensitive skin or allergies, and then you should opt for designs that are specifically dust, dust mite, pollen, or allergen-proof. I would choose the most waterproof options with a terrycloth top layer if only for spills and wetness.
• Materials – Most mattress encasements will consist of fabric such as terry cloth, polyester, and lycra, with vinyl or plastic layers for waterproofing protection. Some are only water-repellent and still quite breathable. Lycra may also be used in the blend to add stretch for easy folding over your mattress. Terry cloth may be used on top, generally, cotton, which will absorb moisture and liquids from sweat, spills, or accidents; however, the waterproof underlayer will prevent it from seeping through. The terry cloth and upper fabric layers are generally quick-drying and moisture-wicking.
• Protection Levels — Most mattress encasements offer different levels of protection. Some are liquid repellent, while others are fully waterproof. Some are designed to resist allergens and dust, while others are more breathable.
• Closure Most Mattress encasements will have a secure zip closure. Check that the zipper has a cover flap or lock at the end, which matters for bed bugs.^[2]
• Machine Washable – Most mattress encasements are machine washable. However, not all can be dried in a tumble dryer as the waterproofing membrane may come off in time.
