Since we have used this cover/topper for a week, we are both very happy with it. It is a little warmer, but not too warm...just helps to keep the bed at an ambient temperature. We both seem to toss and turn less frequently, so we are sleeping better! At the suggestion of the Seller, I put it in the dryer and air fluff and I plan on doing it every week when I wash sheets. We moved to a much colder climate and I was miserable last year because the bed was cold even though we use an electric blanket (top sheet was warm, bottom sheet wasn't)...think this winter is going to be much better!I love this mattress pad. It definitely keeps me cooler and its soft to the touch. Maybe because it's cotton and not polyester. Only downside, the straps are tight and it could be that my mattress is really thick. The one strap broke but I moved a tad and sewed it back on and no issue. I didn't find it being fluffy, but I didn't follow the recommendation of putting it in the dryer first. I will be doing that today to see if it makes any difference.Unfortunately one of the elastic bands ripped right away but I contacted the seller and they were great and refunded my money! The topper is still useable, though it does move around in the night and has to be readjusted. Comfortable and coolI just pulled the Duck and Goose (D&G) mattress topper from its package and installed it on my bed. I’m now lying directly on it (sans sheets) and it is exceedingly comfortable. This topper is thick enough that I’m literally sinking into the sublime padding, and my mattress underneath is there but it seems far away.Mind you I have a nice traditional mattress already with a respectable cushioned layer (not gel based) at the top of the mattress that is pretty comfortable on its own. So I wasn’t specially looking for a mattress topper on Amazon, but what often happens to me who regularly browses the site, I come across an item that I didn’t know that I needed or, more often, wanted, and this is what happened with the Duck and Goose mattress topper. I stumbled upon it and seeing that is was well rated, I was intrigued enough to click on it to read more. After reading the product description and the plethora of favorable reviews, my interest was piqued enough that I decided to purchase it and see if it was as heavenly an experience as the reviews said.Allow me to add that this wasn’t the first mattress topper I have owned; however, all my previous toppers were thin in comparison to the fluffy D&G topper with its two inches of padding. The much thicker padding on this topper made me think that what I was buying was going to be far more than a mattress protector, which had been the sole function of my previous toppers.As soon as I laid back on this mattress topper, I knew without question that it was way more than a mattress protector, as I had hoped. The topper is so padded I expect it will be a tight squeeze in my washing machine for sure, so I will be more careful about eating and drinking in bed. But it is so worth that comprise to have this super fluffy topper to fall into every night and my occasionally afternoon nap. Luckily, it will fit into my dryer easily enough and that is essential to keep the fluffiness factor at maximum, so says the included directions.I honestly don’t know what the “extra firm mattress topper” means in the heading by the manufacturer, because there doesn’t seem to be anything firm about this topper, it just feels super comfortable.This mattress topper turned out to be a smart purchase. I had read a solid number of favorable reviews, as cited above, before I made the decision to buy it. Admittedly, the topper wasn’t an item that I could justify as being needed, but with what I had read I felt the topper had the potential to be a great addition to my bed, and it might even help with my sporadic lower back pain.I’m happy to report that the topper delivered in both areas. It markedly enhanced the comfort of my bed ten-fold and the thick padding has helped with my moderate back pain. It almost goes with out saying that I highly recommend this D&G mattress topper to take your comfort in bed and sleep to the next level.In fact, I am so loving this mattress topper that I have decided to buy a queen size version to give to my sister for Christmas. I know my sister has a bed that I would categorize as average; she definitely spent fewer than a $1000 for it, and it’s not one of those now popular gel beds that can be had for barely $500.Therefore, I feel confident that this D&G mattress topper will thoroughly be appreciated and enjoyed by my sister. She doesn’t know it yet but post Christmas her bed will be considerably more comfortable. And this mattress toppler is exactly the kind of gift I most like giving. A gift that someone doesn’t even know they need, but are thrilled when they try it out and realize what they were missing.I sincerely hope you found this review helpful, and if it was, please click the “helpful” link below. Thanks and pleasant dreams!I could definitely tell the difference. I slept cooler and my cold blooded wife did not complain about being cold either.Great topper but one strap broke while putting around my 18 Full matress.its greatI like the fleece side better for under sheet. The “cool” summer side is crumply. You can’t use a sheen type of thin sheet must use thick heavy weight sheet over this.It’s pretty soft, but I’ll probably only use it in the winter bc this is like laying a puffy blanket under your sheets. I don’t know… too late to return.I read a ton of reviews before I settled on this topper. I have a supportive but firm latex mattress and I wanted a pillow top for some added cushion. I didn't need anything super thick and this was just perfect. I followed directions and popped it in the dryer for 30 minutes. It fluffed right up. The corner elastics work well and the fluff is evenly distributed. I'm really happy I chose this topper. My bed has never been more comfortable. If I remember I'll come back after a few months have passed and leave an update.This product is just ok. I have a very deep mattress 20”, and the straps do not fit around the mattress. At best I think the straps would only go around a 15-16” mattress comfortably. It works well enough the just sit on top of the mattress. I did try to force the elastic and ripped the straps completely. The cooling part is not correct. Do not buy this for a cooler sleep. It looks plush in the photo but doesn’t give extra softness at all. I give it 3 stars because I am keeping it but the description is completely wrong.I get really hot at night and can't use a lot of toppers. This one is great, it doesn't make me hot at all. I wish it was a little thicker but if it was, it'd probably get too hot so all in all, it's perfect. Thanks :)The mattress pad is cool and comfortable however not entirely cool enough when I have an intense hot flashI bought this to help elevate night sweats cus it says cooling. This product increases body heat and is not for temperature control.
