Bought this because we had bedbugs (aaaargh), got place treated, and didn't want a return event. They are soft and supple, and have worked very well. Even spills don't go through. Recently I washed and bleached them back to looking like new. Easy to put on (no pulling, huffing and puffing!). Every home should have these.
I purchased this for my son's dorm room and am very pleased with it. The encasement can be separated into two pieces (making it easy for one person to put around the mattress), or leave attached. Seeing how many college mattresses can be a haven for bed bugs I'm glad I purchased one that completely encases the mattress.
