Easy to put on and doesn't interrupt sleep. I don't even notice it on the bed, but provides great protection from bed bugs. Highly recommend for apartment living where neighbors may bring in bed bugs that spread through out the building.
Before my family went through allergy testing, I thought it would be good to encase the mattresses and box springs to keep dust mites at bay. Then I found out that we are not allergic to dust mites, but I think the encasement is a good idea anyway.
