## Description

Waterproof Mattress Protector

Review: Just Plain Perfect Mattress Protection - These are the best mattress protectors I have ever purchase. They are soft and thin and you barely know they are under the sheets. They are waterproof and just plain perfect. They are not quilted so there isn't that weird feeling you get laying on quilted protectors. They are as soft as a sheet. I would highly recommend these.
Review: Wonderful for 12-14” top mattresses/Split King. - I have a 12 inch top mattress Split King, (measure your mattress) this mattress protector fits perfectly without strenuous effort to put on, has plenty of elasticized material for underneath the mattress to protect from coming off, I believe that you could comfortably go to a 14 inch top mattress but maybe no more than that I would say, for ease with placement. You can make that call from the photos provided. But I love it, finally found one that fits the bill in all ways, feels durable and not cheap. I’m very pleased with this purchase and definitely recommend it.

## Questions & Answers

**Q: What is the thread count**
A: The protector is knitted so there is no thread count. Thread counts are normally for woven fabrics such as sheets. But the weight is 200 g per square meter.Hope this helps.

**Q: Does this mattress protector work for my 15 inch deep memory foam mattress?**
A: I didn't measure my old mattress but my new Topper is 4".  I managed to stretch the protector enough to tuck under both; however, it was an effort and the top edges of the "tucking in" portion are visible on the top of my topper.  I doubt you can use on 15" mattress

**Q: Which side goes up? Does it matter?**
A: On mine it’s the center of the bed. It’s just an air bubble whenever you sit on the bed. But after a few minutes it goes down. It personally doesn’t bug me at all.

**Q: Would this be appropriate for an adult with incontinence?**
A: I would say it is. I bought one for my daughters bed & our bed because we were potty training her & sometimes she would sneak to our room to sleep. These were a huge help because nothing would speak through to the mattress.
