Quality

Look for bed bug mattress encasements that provide proof of effectiveness during testing against bed bugs from an independent laboratory. (Many cover makers will have this information on the product packaging.) The materials should be tightly woven and sturdy to prevent rips and tears. Since zippers are a vulnerable area where bugs can escape, there should be a layer of extra protection around the zippers.

Comfort

No one wants to sleep on a loud mattress cover. Select a cover that does not crunch or squeak when there is movement in the bed. While a waterproof cover is a good choice for a child’s bed, waterproof materials are usually less breathable and trap heat close to your body. Water-resistant covers are more comfortable and often use fibers that wick moisture away from the body.
