Review: Hot Sleepers Look Here - I desperately needed to cool down at night, this mattress pad has really improved my sleep comfort. It fits my super thick mattress well and feels cool even through sheets. It's not magic though, it warms with body heat, but still helpful for anyone else who identifies as desperate for relief. Very soft and comfortable, but if you're looking for plush this wouldn't be the best buy. The cooling is the star, the little bit of padding is just a bonus.
Review: This mattress cover is excellent, and the cooling actually works! - I bought this replacement mattress cover because my other one kept shifting (within days of making my bed, previous covers would move and cause the sheets to get loose on the bed) and because I’ve had problems with night sweats for years. It takes care of both issues extremely well! I’ve had no problems with the sheets moving, nor have I overheated once. It seems like it’s the first one I’ve bought that I haven’t had any problems with. I bought the white cover, which has a very comfortable quilting and makes it feel very soft when laying on it. Because of how soft it is, I was worried that this was going to be another waste of money. However, I’ve been pleasantly surprised, and despite weeks of sleeping on it, I have not overheated at night once, nor have the sheets moved. I uploaded the picture to show how deep the corners are and how comfortably, but snug, they fit under a deep mattress with a topper on it. I have a regular mattress on my bed and a 4” foam mattress topper, but the mattress cover fit perfectly over the deep corners and still had enough room left to go several inches underneath each corner. There is a wide elastic band that goes around the entire edge that make sure there is a snug fit, but without being too tight. The mattress cover fit well in my washer and came out still looking great. I haven’t had it very long, so I can’t yet say it’s durable, but the few weeks I’ve had it, I haven’t noticed any runs in the corners when I change the sheets, which is already an improvement over other covers I’ve tried. I’d certainly recommend this to others. It is a great value for the money and I don’t think you’ll be disappointed.

## Features

- Microfiber
- 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.
- SATISFACTION PROMISE - SLEEP ZONE has more than 40 years' experience in the design and manufacture of high-quality bedding. Our products are certified by Oeko-Tex. You can buy with confidence under our excellent product quality and customer service. If you have any inquiries or issues

Soft and comforting. I'm warmer with it, not cooler. I don't know how to make it make me cooler.
