Honestly, the biggest difference between these two mattress protectors is that the Sleep Tite protector can fit mattresses up to 22-inches thick while Luna fits up to 18-inches. Otherwise, these two protectors are incredibly similar (even in price).

Both protectors were a little too big for my 10-inch thick Casper mattress. There was excess material around the edges that caused some shifting and some slight noise on my mattress.

I think the saving grace for the Sleep Tite protector – and what caused me to rate it slightly higher than Luna – is the “Universal Fit” element that Malouf offers. The elastic gripped my mattress and held the protector as closely to my mattress as possible.

I felt less overall shifting and noise (and generally just noticed the protector less often) with the Sleep Tite than the Luna protector, which is why I made it my personal choice.

That being said, depending on what type/size mattress you have, the Luna could also be a great fit.

Both mattress protectors are sold on sites that offer them at discounted prices (those prices change frequently so keep that in mind).
