What is the opinion of Reddit about the
Luna Premium Hypoallergenic Zippered Bed Bug Proof Mattress Encasement 11″ Height – Twin Size – Made in The USA?

I’ve used these Luna ones & they’ve worked well for me. For the mattress I’d recommend a zippered-one that completely covers it, as opposed to an elastic one that sites on top/sides.
