Does it cover the bottom of the mattress?

Yes. It is a full encasement that zips around the mattress, so the top, sides and bottom are all covered.

Will it help with dust mites or bed bugs?

The sealed, six-sided design is made to keep dust mites and bed bugs out of the mattress and contain any already inside.

Owners generally describe it as quiet and not crinkly, unlike some plastic-backed protectors.

It has to be unzipped and removed from the mattress to be washed, then refitted.

It adds a thin layer and slight bulk, but most owners say the feel of the mattress comes through.

It takes some effort and is easier with two people, especially on a thick mattress.
