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

  • Supportive, eliminated back pain, comfortable.
Color: Grey Size: Queen
My bed the way it is hurts my back so I got this "fluffy" mattress cover to try to help make my mattress a little bit more comfortable. I have bought multiple mattress toppers with memory foam, down alternative, you name it. None of them have helped my bed feel any more comfortable. I wanted 100% cotton but everyone that I invested in didn't do squat to help me. I decided to give this one a try even though it's polyester. After all my sheets that cover it are an amazing Egyptian cotton so I decided to just go with the cheaper polyester mattress topper to see what happens. Well last night I slept very well. I was extremely comfortable and my back did not hurt when I woke up. I used a memory foam bed topper and then I put this mattress topper on top of that. The topper is plenty deep to cover my entire mattress and it's about 14 in deep with the memory foam. It stayed in place all night long and I slept like a charm. It does not have a cooling effect that I noticed and it is not extremely fluffy but it did help me to sleep more comfortably and I did not wake up with back pain. If you're looking for something extremely fluffy this is it. If you're looking for something to give your bed an extra level of comfort, support, and to eliminate back pain this topper seems to cut it. I'm finally satisfied. Sometimes the best quality and more expensive and highly rated item is not where it's at. In my case the cheaper polyester mattress topper did the trick. ... show more

  • Like an added blanket
Color: Grey Size: Queen
This is my 3rd one 1st one was a full I upgraded to a queen and gifted it to my sister then I bought this one as my second one to have so that when I'm washing my other one I can have one on my bed at all times the only thing about this one is that it is an inch to 2inches off on the sides like it's not a queen size but the corners fit hopefully over time it stretches but Ive had this pattern before and it fit wonderful this one on the other hand is missing an inch on both sides but I got this cause trying other ones with cotton just don't seem right to me cause I would hate for it to tear and the cotton come out at least I know this brand hasn't done that to me so as for the padding it's not so thick it's is comfortable however if your looking for for fluff this ain't it it's like an added blanket washability is good although I hang dry mine mostly so I don't know about the dryer . Waterproof not so much cause It'll still have spots of stains if you got kids but they do come off and for Pain relief you will have after a long day at work. Long review but hope this helps God bless. ... show more

  • A cooler nights sleep
Color: White Size: King
I was pleasantly surprised how this kept the temperature of the bed cooler. I had tried others and they did not work. I tossed and turned less. There was no odor and installation was easy. I do have a thicker mattress and the fit was great.

  • Apparently a black mattress cover is what I needed in my life
Color: Black Size: Queen
Why did I ever buy white mattress covers? Black looks so much sleeker and the inevitable stains will not be so visible. Love it. Soft and easy to put on the matress.

  • SWEAT AND MORE SWEAT :(
Color: Beige Size: Queen
It gives the expected comfort of a bed topper, feels fluffy... HOWEVER it became a nightmare, I no longer sleep well because it will make me sweat! Probably it's more convenient for cold weather, but even with the fan on, I'm still cool but sweaty, it's become super uncomfortable and I regret my purchase, I didn't know it would be that bad. I only put my fitted sheet on top, and still makes me sweat. Do not recommend for warm weather or if you're a hot sleeper. ... show more
