I am very pleased with this bed cover. It is very well made and fits my bed perfectly.  I love that it is for allergies as well as pet dander, bed bugs, and other things in your house that may cause allergies.  It is 6 sided and encloses your mattress by zipping. This bed cover is also waterproof.  The fabric that it is made with is extremely soft and best of all it is machine washable.
