12 - 18 Deep , Full XL : The Original Sleep Defense System - Waterproof / Bed Bug / Dust Mite Proof - PREMIUM Zippered Mattress Encasement & Hypoallergenic Protector - 54-Inch by 80-Inch, Full XL - Standard 12"

This is a great product! My twins had them on their dorm beds last year and it was nice knowing we didn't have to worry about bed bugs or whatever was on that icky mattress! I am buying them both bigger ones this year for their apartments, because of the same reason! Easy to use, soft and washable!

I am very pleased with this mattress encasement. I have a Full size 14 inch mattress. I purchased the Full XL size for up to 18 inch depth in the mattress encasement. It is just slightly larger than needed but not by much which is much better than too tight with a risk of tearing. To me, it fits perfectly. The deep pockets made it easy to put on. I don’t hear any sound when moving on the mattress either so the sleep quality and comfort are both high on rating. I also have a thin mattress fitted sheet on top. The material and zipper are perfect: strong and thick. The product even has ties to make sure the zipper doesn’t move, together with Velcro patches just in case there are tears. I highly suggest purchasing this mattress encasement even if you have to spend a bit more compared to other options on Amazon. Bravo!

Perfect for me because I found out at allergens testing I’m allergic to dust mites like highly allergic. The helped me so much. Just wash weekly and watch your dust mite allergies or skin itching subside

Easy to put on and workswell
