Can the cover be removed?

Yes. The coverlet zips off, so it can be taken off for cleaning or replaced.

Our take on the Mainstays 7.5 in Quad-Fold Metal Box Spring, Queen

The Mainstays Quad-Fold Metal Box Spring is a 7.5-inch low-profile foundation for a queen mattress. Its metal frame folds flat into quarters, so it is easier to carry through doorways and store than a rigid box spring. A removable zip coverlet with a no-slip surface goes on after unfolding. It suits shoppers who want a simple, low foundation and who don't mind assembling it. Against traditional coil box springs, it is thinner and lighter but offers less height and no spring give.
