- 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.

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.

I got this to help with the sleeping in the hot summer night and was suspicious about the cooling effects. I tried it for three nights now and I am really happy about the product. It is soft and did keep me comfortable throughout the night!

It fits well on the sides and doesn’t slide around all over the place. It appears to be well made also. I haven’t slept on it yet but it looks comfy.

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

Purchased in May of 2022 and they're still going strong in May 2026. I only had one small problem after a few months with one of the pair I bought, but the seller resolved it immediately, and otherwise there have been zero issues. They hold up well in the wash, the fabric is smooth with no pilling at all. They have not shrunk nor stretched. As for the cooling, it seems to help a bit if you sleep hot, but the main reason I got them was they were the right size for my Japanese shikibutons and they fit well as the elastic gathers underneath perfectly. The add a nice layer of cushion between the bed and the sheet and help keep the shikibutons clean. Very happy with these and would certainly buy again.

If this were listed as just a mattress pad, I'd give it 5 stars. It fits nicely and is comfortable. I like that it's the same color as my sheets (grey). As a plain mattress pad, it's great. However, it was listed as a cooling mattress pad, which is why I bought it. Purchased it because my spouse sleeps hot, and I sleep cold. First night with this and I was BOILING. This should be great for me in the winter. But unfortunately, it is not functioning as advertised.

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.
