Review: Mattress covers help to protect and give longvi - These water proof mattress covers are excellent choice to protect your mattress from spill and food spills. They are strong and fits the mattress very good. They don't feel strange after dressing the bed. Infact, they are comfortable to sleep or rest on. The construction of the cover is sturdy, seams are doubled stitched and doesn't smell like plastic. These covers stay in place
Review: Fits great, super soft and easy to put on... - I love these washable mattress covers. We have repurchased these over and over again. I DO NOT KNOW IF THEY PREVENT BED BUGS. But Google says polyester prevents bed bugs. I use to help manage sober living homes so we purchased covers like these all the time for mattresses so I'm pretty familiar with these. I prefect them over plastic because it's not "crunchy" on the bed while you roll around.
