Babesafe mattress covers

Hi all. Anyone use babesafe mattress covers for their LO's crib? I co-sleep with my son on a Queen mattress and I wanted to get a mattress cover but haven't had much finding one. My mattress is new and I'm scared of SIDs, especially because the complex I live in is suspect to mold and just Lots of bad icky things. We are moving soon but in the mean time I want to find a mattress cover that is like the babesafe ones but for my Queen mattress. Any other parents out there use one?
