Features

  • Microfiber
  • THICK MATTRESS TOPPER - This mattress topper is overfilled with 8D down alternative fiber filling, fluffy and supportive, providing stress-relieving support for your hips, shoulders, back, and knees. Ideal for side, back, or stomach sleepers. This thick plush mattress cover will save your old firm mattress and refresh you with a luxurious sleep experience.
  • BREATHABLE COMFORT - We use an embossed fabric as the surface; it's soft and breathable and treated with Nanotex Coolest Comfort Tech, which accelerates the wicking of moisture. The premium spiral filling allows more airflow in the topper. With good breathability, you won't have issues with overheating, even though it's a thick mattress topper.
  • EXQUISITE DESIGN - Baffle box quilting keeps the filling in place and helps distribute body pressure evenly. The raised four sides prevent the filling from leaking out. It seems to wrap you comfortably, and you will feel like sleeping on the clouds. The white hemming makes this gray mattress pad more stylish and modern.
  • DEEP POCKET & EASY CARE - The knitted skirt pocket stretches up to 21 inches and can fit mattresses 8-15 inches deep. The 1.6-inch-wide sport elastic trim can securely hold your mattress pad in place, and its excellent elasticity makes the pad easy to fit and remove. No shifting, no noises, ensure a restful and uninterrupted sleep. The mattress pad is machine washable. Tumble under a gentle cycle and air dry naturally to make it fluffy again. Please do not bleach, iron, or dry clean.
  • OEKO-TEX CERTIFICATION - SLEEP ZONE, with more than 40 years' experience in the design and manufacture of bedding, has a commitment to quality. Our products are OEKO-TEX Standard 100 certified, so you can buy with confidence.

  • This mattress cover is excellent, and the cooling actually works!
Color: White Size: Queen
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. ... show more

  • Better sleep for me now...
Color: Grey Size: Queen
I had the standard mattress pad cover for my mattress (queen sized), however, did not get a comfortable sleep. When I saw this item, thought I would give it a try. It is over the previous pad and fit perfect, no issues. My mattress was completely covered over and under, holding well. The cooling effect, though minimal depending on one's body heat at night was enough for me; no icy cold, so it depends what one's expectations in that sphere. My main reason to purchase was for comfort and that is where it works more for me. I have had better sleep since combing both (the original pad is thin so mainly keeping mattress cleaner. The padding, very minute for some, works for me. A good sleep was my goal, and this has worked for me. Great price, good quality, designed well, just enough softness and fast shipping by seller. Comes well wrapped and be sure to let this expand naturally for 24 hrs. This gives time to puff up. Recommend ... show more

  • Stays put and very comfortable
Color: Grey Size: Queen
Bought one about a year ago, and very happy! I tend to toss and turn when I sleep and EVERY mattress pad I've had in the past never stays secure on the mattress and I was constantly having to adjust it. Not a problem with this one, it stays put and us extremely comfortable. Highly recommend!

  • Improves sleep quality
Color: Grey Size: King
I love this mattress topper! This has helped my quality of sleep improve so much! Its perfect size and fit. It doesn't come off my bed like most sheets do. It's a really good quality. I have been using it during the winter and it helps keep us warm but not overly warm. It's a great mattress topper!
