Hi majorleague,
Welcome to the Mattress Forum!
I haven’t talked recently with the different vendors in the component post here (scroll down for the covers section) about all the cover options they currently have available (websites are often not up to date) but the SleepEz cover would certainly be among the better options. Most of the others also carry unquilted covers as well as far as I know.
I’m looking forward to your comments about your new mattress and the cover you selected.
