My son uses this along with the Lucid Foam matress and he loves it. It is silky soft and eady to put on. It zips over his entire matress and foam matress togethet leaving eaverything tight and in place

### ⭐⭐⭐ Nice, soft material
*by Y***K on December 11, 2015*

Nice, soft material. Not plasticky or smelly. I have a natural latex mattress which I seem to have developed an allergy to. I was hoping that this would prevent me from itching at night, but it did not, so I returned it. After purchasing 3 different encasings, I finally found an encasing that does actually prevent me from itching without feeling hot and sweaty or plasticky: protect-a-bed.
