Review: I couldn't find anything similar to these at any store in India, and I looked everywhere. They're an excellent bedbug barrier but don't make you sweat at night. It was worth the extra cost of importing them.
Review: Really awful fit - and the top is a horrible material which crinkles and makes a noise when you lie on it. Would not recommend

## Questions & Answers

**Q: My mattress is 14' high-will this fit?**
A: Previously this may have fit, but not any longer. The package doesn't look like the original that I had. No where in the description above does it say what mattress depth it fits. 

I tried for 30 minutes to get this thing on my mattress.

**Q: Hello, the bag says dust mite barrier, is barrier the same as protection? does it fully protect from dust mites?**
A: My son has a huge dust mite allergy that he had to take medicine for. Since we got this he hasn't had an issues and no longer takes medicine. This really does protect against dust mites.

**Q: Does it smell?**
A: No it doesn’t smell, it’s perfect. Wash it before you put it on and it protects your pillow. My daughter uses it as a pillow case she doesn’t even put a pillowcase on top of it

**Q: Does it include boxspring covers?**
A: My boxspring and Mattress was about 16 inches total. The cover fit over both together.

### ⭐⭐⭐⭐⭐ Review
*by S***R on July 14, 2025*

Chose the AllerEase Ultimate Allergy Protection Ultimate Cotton to help cut down on allergens from our mattress. Amazon states that this product is returned frequently, so a few details: Item is difficult to dry after washing as stated in reviews. Due to waterproofing the mattress cover comes out of the wash dripping like a plastic bag, plan on hanging the mattress cover for a few days to allow for air drying, then toss in dryer for a short period to fluff. Note that we noticed that the cover seemed to stick together in a few places when we tried to dry it in the dryer for over 15 minutes, air drying with a short fluff in the dryer worked beautifully. Fits the mattress nicely, slides over like an envelope with a zipper closure on one end. A definite two-person task to put the cover on. The cover does have a waterproof feature so it does have the "crinkle" sound, however the ultimate cotton feature on this cover refers to the top which is softer and quieter for sleeping. Also purchased the pillow covers to cut down on allergens. So far we're noticing a marked difference in the mornings, waking up with no stuffiness or sneezing. A good purchase for us at a fairly reasonable price point. Quality: Nice zipper seems to be good quality Comfort: Ultimate cotton top provides a more comfortable, less "crinkle" sleeping experience
