This mattress topper is both high quality and confortable. It fit perfectly on my bed. It appears to be water resistant. It cools your body and does not hold hear like other mattress toppers! It's light weight and great quality! I love it! A must try!

Very well made, the second one I’ve bought since we stole the first one from the guest bedroom to put in our new RV! It actually makes the sleep better by adding that extra bit of cushioning. It was a perfect fit so no corner straps were needed, saving a bit there and the price is excellent! We have a tiny puppy who thinks he needs to hide his bones under the pillows and thank goodness for this mattress cover. I still have to continually wash the sheets Charlie gets greasy. I probably need to put plastic over the whole bed, lol I definitely recommend this mattress cover!

TLDR: comfy, fluffyish, and soft. Not cooling as claimed, minus a star. In Depth: Last summer we spent way too much money on an Aireloom mattress. To protect our purchase we had bought a mattress protector that was basically the equivalent of a baby’s crib mattress topper- plasticy on the bottom with not much stretch to it. For the past year I’ve been telling my husband that I can’t believe our mattress hasn’t broken in yet; it still feels way more firm than what we felt at the store. Well, the other day I took the mattress cover off for cleaning and laid down on the bare mattress to see how it felt. Oh my gosh. It was a completely different mattress. So much more plush and comfortable! The mattress protector had been so tight and un-stretchy, it wasn’t allowing us to enjoy the medium-firmness of our pillow top mattress! I immediately threw it out and went to Amazon to search for a 1-day delivery of a new mattress cover- this time one that would move with the flexibility and plushness of the mattress. This one had excellent reviews and a reasonable price tag, so I went ahead and ordered. Upon arrival the next day, I removed it from the shrink wrap and threw it in the dryer on steam refresh. The little pillow pockets puffed up a bit, and I put it on the bed. It didn’t have any bad smells or issues. It fit my deep sided queen size mattress perfectly. Then came the moment of truth. I laid upon the mattress and was overjoyed- the new cover kept the plushness and firmness of the mattress itself! Now, we have slept on it for about a week. It definitely is NOT cooling like the description claimed, and that is a bummer. But, I haven’t noticed any significant heating either. It seems pretty neutral temperature wise. The best part about this is that I didn’t tell my husband that I had replaced the old mattress cover. I wanted to see if he would notice the difference. Within the first few nights he kept commenting, “this bed is sooo comfy!” And “I love this mattress!” Little did we know that we could have been loving it this much for the past year had we had this mattress cover! Get it for the comfy compliment to your current mattress, not for the cooling, and you’ll be happy. **Update a month later: still loving it! I finally told my husband that I had changed out the mattress cover. His response? “No way... I thought that the mattress had finally broken in! I’ve been sleeping SO MUCH better!” Then he showed me his sleep apnea machine, which keeps a record of how many hours he wears his breathing device each night. In the first week of having the mattress cover, the record showed an increase from 5hrs/night to 7hrs/night average!

It has very deep pockets. It's a good quality item & is already made the bed much more comfortable. I have a pillow top queen and it fits great. I used corner clasps to attach it to the sheets as well.i like that it's blue to hide dingy. I'm disabled and spend a lot of time in bed, its a pain every week to do the baking soda & mattress trick so this was the next step. It's much easier to wash this weekly than air out, dry, treat & vacuum mattress when cats are jumping around. I'm very happy & the blue is identical to the photo. Great cost as well!

I would not consider this a true topper. The difference is minimal in terms of comfort or support. The plush aspect is superficial at best. The thickness appears fuller than it really is and when compressed it is very thin. Talking less than an inch of any substantial material. Maybe the superficial plushness is all some people need, but for anyone else it is hardly tangible. It will add some superficial loft or fluffy texture to the feel of your mattress as you initially lay on it which is nice and descent for $30 I guess, so maybe I didn’t waste my money, but unless you’re sleeping on floor boards, it does not make a significant difference comfort wise because of how thin it is. As a pad, I would not personally choose this as such because I prefer something less permeable. This material I feel like I’d have to wash fairly regularly, so I put it under another mattress protector. This is also not cooling. If anything it’s slightly warmer. Maybe it could be considered cooler than memory foam I suppose but I find the “cooling” statement misleading (as well as how plush it looks in the official pictures). I’ve searched a lot on Amazon for a nice comfortable mattress topper and what I’ve come to is that unless you want spend big bucks, $200+ (which theoretically could save you money instead of trying and not liking 2 or 3 different off brand toppers), lower your expectations or go to the web and look for more or less name brand or professionally reviewed toppers, i.e., Parachute’s down alternative topper. This product has made me leery of purchasing any mattress toppers on Amazon, even the ‘Amazon recommended’ ones.

I recently purchased the Queen Mattress Pad Cover Cooling Mattress Topper Pillow Top with Down Alternative Fill, and it has truly transformed my sleep experience. This mattress pad cover combines the best of both worlds – a plush pillow-top feel and innovative cooling technology. One of the standout features of this mattress pad cover is its cooling capabilities. The top layer is crafted from a breathable and cooling fabric that helps regulate body temperature throughout the night. As someone who tends to sleep warm, I have noticed a significant improvement in my ability to stay cool and comfortable, leading to more restful nights. The pillow-top design adds an extra layer of softness to my mattress, creating a luxurious feel that enhances the overall comfort of my bed. The down alternative fill provides a cloud-like cushioning effect, cradling my body and relieving pressure points. I wake up feeling more refreshed and well-rested, thanks to the added support and comfort this mattress pad offers. The construction of the mattress pad cover is of high quality, with durable stitching that ensures longevity. The elasticized skirt makes it easy to secure the pad to the mattress, preventing it from shifting during the night. The deep pockets accommodate a variety of mattress sizes, ensuring a snug fit. Maintenance is a breeze, as the mattress pad cover is machine washable. This convenience adds to the overall appeal, making it easy to keep my sleep environment clean and fresh. In terms of value for money, this mattress pad cover is a wise investment. It not only protects your mattress but also enhances the sleeping experience, turning an ordinary bed into a haven of comfort. If you're looking to upgrade your sleep setup, the Queen Mattress Pad Cover Cooling Mattress Topper Pillow Top with Down Alternative Fill is a fantastic choice that delivers on its promises of cool, comfortable, and rejuvenating sleep.

I had the best night's sleep in a very long time! This is well made, very padded, and oh, so comfy. The sides go to the edge of the mattress. Pockets are nice and deep. The softness reminded me of a bed I slept in at a major hotel years ago. It was amazing. I washed and dried it before putting it on the bed. It dried quickly. I know you're not supposed to dry these with heat but I used the cotton temp. No shrinking! I never use clothing or blankets, etc. until I wash them as during manufacturing they use chemicals. Need to wash them away! If you're looking for a great mattress pad at a good price, I highly recommend this one.
