Review on RV 6 Sided Zippered Mattress Protector With Secure Locking Zipper For 70X80 RV King. Creates A Natural Seal Around Your Mattress From Dust, Pet Dander, Pollen, Liquids & More. Oeko-Tex Certified… by Evan Roberts

i bought these to enclose our camper mattresses. They are older and I just don't like them which means I don't like them touching my other bedding. I know, I drive my husband bonkers. Anyways, these are really generously sized. We have queen short beds and the queen short I ordered was more than adequate and almost too big (yes, I got the correct size). I could have easily fit my 3" mattress topper inside as well, but as I stated before, I was more trying to just cover the old mattress. nice material, easy to zip and unzip. Would buy again. I washed and dried in hopes it would shrink a little but it did not.
