  • Game Changer
Size: Queen Color: White
Tried out more than 15 mattresses at a bed store - began to think we weren’t going to find one. Then we found it - our perfect mattress. We gave it about a five-minute test and agreed, very firm but perfect. Then we spent our first night on it. Not good. We figured there’d be an adjustment, give it a few days. Nope. Couldn’t adjust. Always the option of sending it back and trying again but decided to order this mattress pad and see if we could live with our mattress. Best night’s sleep ever. Perfect combination. We’re keeping the mattress. The instructions on how to fully fluff the pad are clear and easy to follow. Also says you can do it again if at any time you feel the pad needs it. The deep pockets are fantastic, and the top fit perfectly, no sliding or movement. Can’t recommend this enough. It’s definitely a game changer! ... show more

  • Comfortable
Size: Queen Color: White
This mattress topper is really great. It makes the bed so much more like you are laying on a cloud and so Inviting. The size fits perfectly for our queen size bed. It does not hang over(the topping part) and I really appreciate the long pockets so that it tucks under the bed so well that you don't have to worry about it shifting while your sleeping.I don't know if it is leak proof or not as I have been very careful not to spill ANYTHING on it, but as thick it is, as long as you don't pour a whole glass of water or, whatever you drink, on it then it shouldn't get to the mattress. It is very breathable and airy. It is not a memory foam topper, but instead it is cotton, but it does not change the fact that this topper is very comfortable. Now, if you have a really bad mattress that is hard as a rock or is a memory foam with permanent sunken places where you have slept, this will not help. The only thing that will is a new mattress. Trust me, I know because I use to have a mattress like that and I tried every topper there is to make it comfortable to no avail. Remember, you need to turn your mattress every few months to prevent permanent indentations! The mattress we have right now is 4 1/2 years old and turn our bed often, so this topper does a wonderful job. The color does not matter to me because we don't sleep directly on top of the topper. We use sheets over it. Speaking of sheets, if you get this topper, you should keep in mind that it makes the height of your mattress a bit taller, so when you buy sheets, be sure the have deep pockets or the sheet will not tuck under the bed. Overall, I recommend 100%+ ... show more

  • Very Early Review That Will Be Updated If Needed
Size: Queen Color: Grey
05/13/25: So far I love this mattress topper. Beautiful in gray and looks exactly like the picture. I followed the directions for unpacking and fluffing in the dyer and was not disappointed. I bought the queen size and it is huge but I expect, from what I see, that the comfort will be too. That's what I was looking for. Will be using over a queen air mattress that is too firm for me and this will solve that problem. Unpacking was easy and it came out of the compressed package easily as well. I took the time to let it naturally decompress on my bed for several hours before I ran it through my dryer on low for 20 minutes. It fluffed fully in the process and I'm very pleased with the look and feel. If you need a mattress topper, in whatever size, this is definitely the way to go and I would buy it again without hesitation. ... show more

  • Soft, fluffy and definitely recommended!
Size: Queen Color: White
This product is very comfortable, soft, a little loose fitted, quiet and (so far) durable. I washed it the first day I got it and put it on right away, its held up great. It refluffs on its own so when its time to get back in bed its like being surrounded by clouds! (If clouds were able to be slept in!😊) ... show more

  • Mine puffed up beautifully!
Size: Twin Color: White
I read a lot of the reviews and looked around on Amazon for quite a while before settling on this one. I did read that some people were disappointed because theirs didn't seem to puff up. I took a chance because I can easily return items purchased from Amazon if they don't live up to their claims. I am not disappointed in mine at all. It puffed up beautifully after 20 minutes in the dryer on low heat and my mother reports that it's delightful to sleep on. It certainly looks like it would be. I am going to purchase one for myself now! ... show more

  • It only softens the surface of the mattress and but does not provide much support for your body.
Size: California King Color: Grey
I had high hopes for this topper, looking for something to improve my Beautyrest Black Series 3 medium firm mattress, which feels like sleeping on a concrete slab compared to the one in the showroom. Mattress Firm is being weird about me exchanging the bed, even within policy terms. I understand it takes time to break in, too, so I was in search of a temporary solution or perhaps something longer-lasting. I bought this topper after reading all the great reviews, especially from someone who had the same mattress and faced the same issue. However, if you're looking for support and a way to soften a firm mattress, this may not be the solution, unless maybe if you are younger. Additionally, if you suffer from chronic pain in your back, neck, or shoulders, this topper may exacerbate your discomfort. However, it may help some if you place a sheet over it to level it. While it looks very sharp and inviting, it ultimately doesn't provide much support and feels like it bottoms out in terms of density. It only softens the surface of the mattress. If you're just after something to make your bed softer, cozier, and comfortable, this could work for you. But if you're trying to resolve a specific problem with a very firm mattress, it may not meet your needs; it was extremely disappointing for me. To complicate matters, my husband accidentally threw away the box, and since the topper is so large, I’m unsure how to return it. I may have to donate it, which feels like a waste of money. 😢 ... show more
