## Features

- COOLING BREATHABLE - Mattress pad with new NANOTEX Coolest Comfort Technology features moisture-wicking and fast-drying to actually balance your body temperature throughout the night. The sleep surface is treated with an embossed process, which is usually applied to sports fabrics, making it more breathable and stylish than ordinary material and bringing an advanced dynamic vibe to your bedroom.
- ULTRA SOFT FLUFFY - We use 120gsm thick brushed microfiber as the sleep surface. Overfilled with 12oz 5D spiral fiber, thicker than most on the market. The fiberfill maintains excellent softness and resilience, making this mattress pad super fluffy. Let you enjoy the luxury hotel level of comfort at home.
- UNIQUE 3-ZONE DESIGN - This mattress pad is ergonomically designed with three zones. The head and foot areas use a wavy design, which can ensure the edge is not deformed. The body area in the middle uses cloud-shaped quilting design to provide a larger body supportive area that disperses the body's pressure and prevents sagging. It helps to keep your body stretched naturally for deep and relaxed sleep.
- DEEP POCKET EASY CARE - Quilted Stretch-to-Fit (8"-21"): knitted skirt pocket stretches up to 21 inches deep and can be easily placed on most mattresses. The 1.6-inch width of high-quality sport elastic trim securely holds your wrap in place, and its excellent elasticity makes the wrap easy to fit and remove. It ensures you get the most restful and restorative sleep. Machine wash cold, do not use bleach, tumble dry low.

## Questions & Answers

**Q: Does this keep you cool while sleeping on it?**
A: The answer is YES. I've seen several people answer and say "there is no "cooling effect", but it doesn't get quite as warm like other fabrics", or "I don't know if it keeps me cool but I haven't been overly hot since using it". That's because the material keeps you cool. It's not an air conditioner; cool air isn't blowing through it. However, in the Summer or warmer days your body will NOT be hot. Thus, it helps keep you cool.

**Q: How well does this regulate tempature.?I sleep very hot and want something that is cooling**
A: I sleep hot too. Not sure how ot does it exactly . I find that the bed stays cooler and I get a much better sleep.

**Q: How thick is this product when placed over your mattress?**
A: You can definitely feel the difference once placed on your mattress. I have an ultra plus mattress and didn't think it would make a difference but it has. Lifetime warranty to boot.

**Q: I have a queen size bed, should I use king size sheets so it will fit nicely?**
A: Yes I also like to use king size but to be honest it covers all comers of the mattress by using the king size sheets all it will do is add too much material under the mattress. The scrunch corners never roll up
Or flap up they stay locked in place is u like extra pull room for your covers when u get under them if it’s tucked under the mattress that will work fine too
