- 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.

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.

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.

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

Comfortable but NOT cooling!! Don’t buy this if you’re a hot sleeper. My goodness i woke up in a huge sweat from this thing, worse than before. I didn’t cool me off at all. My back didn’t hurt when i woke up and it was comfortable just not what i need.

Fantastic fit on my full sized 10" hybrid mattress. No problems getting it on, at all. Super easy. My mattress is a little firm for my preference so I was looking at adding a pad (and actively shopping for) when I saw this. It looked interesting- cooling, adds some loft and softness, fits deep mattresses, attractive. And not over priced at $27 Figured it was worth giving a try. It fits my full sized bed really well. The elastic is thick and does a great job grabbing the underside of the mattress. I am suspect that it would fit a 21" (maybe 12", likely pushing it at 14") mattress, as the elastic just goes under my mattress. But whatever, it fits mine very well and stays put. It was easy to put on and take off (and put on again). I love the teal color, and the overall look. I almost don't want to cover it up as I really like how it looks with nothing else on it. It is kind of giving me ideas for another bed if I see a color that could work. It doesn't provide much of a plush padded feeling. But it does give just a light level of pleasantness. However, it isn't enough so I went and ordered a thicker pad. But I am pleased to have purchased it, and I imagine it will work well with the pad (haven't got it yet). EDIT: what a dream! It works really well over a mattress pad, and the combo is better than either one used alone. Doesn't exactly have a cooling effect, yet it seems to be able to disperse heat more evenly. Like my torso isn't hot when I sleep, but it isn't exactly cool. I think the main function is to keep moisture from being trapped which can make the body feel more hot. I am less hot since putting this pad on, which is a huge positive as my bed gets hot sleeping with big dogs. I think overall it is effective in making for a more comfortable bed. I DO recommend it. Oh one little detail in the packaging. I like how well it was packaged and how there was a strip of cardboard placed just under where the seams meet where one would usually take a box cutter to. If this was intentional then it was super thoughtful, as it helps to protect the mattress pad when trying to open the box. machine wash, tumble dry low.

This is my very first mattress topper and I LOOOOOVE it. I was going to get a California King but the King size fits perfectly. And I have and adjustable platform and it stays in place. There is no odor present and the quality is very sturdy and the fit once it’s on fits very snugly. It is very soft and feels like a memory foam topper. It is very soft light weight considering it is King size. And is truly worth the price. I really recommend this to anyone who has any type of back issues. I have two bulging disc and two chip disc and this feels amazing on my back.
