Must have!!
Color: Dark Gray Size: King
SAVED MY BACK! It’s a soft topper but still able to provide maximum support for my back. It made a difference and saved me from purchasing a new mattress. The topper has deep pockets which makes it more than an amazing fit for my mattress without it slipping! The padding is breathable and DOES NOT trap heat by any means. 100% worth every penny. Quality material! ... show more

Best topper ever! Well made and oh so comfortable!
Color: Dark Gray Size: King
This is the best topper I’ve ever purchased! To most people that may not mean much, however, I’ve bought at least 10 toppers over the years. I have a bad back and really need a firm mattress, my husband also has a back issue but needs a softer mattress than myself. The problem is, with the firm mattress I still often wake up stiff and very uncomfortable. Since putting this on our bed, my husband and I have had drastically less aches and pains upon waking up. I fall asleep quick with this topper & stay asleep all throughout the night. It’s well made, keeps you cool, & is seriously so insanely comfortable! I honestly am considering getting another, just so I have a backup. I do feel it will hold its integrity and last for a while. The pockets are nice and deep for a perfect fit. The padding is so soft and really just made my bed perfect for us! Sooooo happy with this product! ... show more

It Actually Fixed Our Bunching Sheet Problem!
Color: Green Size: King
This mattress topper makes my bed feel like a cloud! I already loved my bed, and this really just made it even better. I primarily bought this because I was hoping that it would help keep our sheets from sliding around. Since it's a little heavier than a normal mattress protector, I was optimistic that it would stay in place better. IT DDI!!! I cannot stand when my sheets get all bunched up, and this totally fixed that problem for us. What I wasn't expecting was tot love the topper itself as much as I do. Every morning when I wake up, I just want to stay snuggled up! I'm a naturally hot sleeper, and this keeps me nice and cool throughout the night without feeling chilly, which I love. We've only had it a few weeks, but so far I'm really happy with it. I put it in the dryer to fluff it up when I first received it, and it fluffed up like a champ! It has nice deep pockets and fits our bed really well. One thing to keep in mind is that if you prefer a firm mattress, this probably isn't going to be the best choice for you. It definitely adds softness to the mattress. If something happened to this one, I would absolutely buy it again! ... show more

Great, But Overhyped...
Color: Dark Gray Size: King
I bought this because I wanted a softer-feeling bed, and my TikTok feed was flooded with people promoting it. It is soft, but it's not life-changingly soft. Granted, I didn't have the hardest mattress in the world. It's cozy and can improve sleep quality. It does its job, just don't expect to feel like you're floating on air. The padding doesn't completely cover the surface of my king-size mattress, but that's just me nitpicking. It covers enough. It does make for a warmer sleep, so keep a fan nearby if you don't like that. ... show more

So comfortable and worth the money!
Color: Dark Gray Size: Twin
Purchased for my son’s twin bed as extra padding. I’m really happy with this mattress topper! It added a nice layer of softness without making the bed feel overly squishy. It’s comfortable, cozy, and has made a noticeable difference in how our mattress feels. I also like that it fits securely and stays in place instead of constantly shifting around. Definitely worth the money, and I would purchase it again! ... show more

The best topper ever!
Color: Green Size: King
I normally don’t write reviews, but this mattress topper absolutely deserves one! It has completely transformed our bed, and I honestly have never slept better! I was worried it might be too bulky, but it’s surprisingly lightweight and fits perfectly over our king-size mattress. The padding is just right—not too thick and not too thin—and it’s incredibly comfortable. Best of all, our regular sheets fit perfectly without any issues. I couldn’t be happier with this purchase! If you’re thinking about getting one, BUY IT TODAY! You won’t regret it! ... show more

Ignore the one star reviews!
Color: Dark Gray Size: Queen
I was getting worried reading the one star reviews after I bought it. Last night was the first night that I slept on it. It was honestly the best night's sleep I have had in a long time. It is definitely the way it is described. I have a disability and this helped so much with pressure points, aches and pains, it does have support to it. I will be honest, it is very fluffy and soft, but your not going to sink into it, if that's what you're looking for then this isn't for you. This makes it feel like your mattress has a pillow top on it. It is VERY comfortable and supportive. Please make sure you follow the directions and let it fluff up. The directions say you can put it in the dryer on low heat for 20 minutes to help it fluff, which was super easy! The reason I am giving this 4 stars instead of five is because it says it's cooling (and it is, to the touch) but it is not going to make you feel like it's been in the freezer, it's more of distributing your heat evenly, I was warm but like a comfortable warm. If you're looking for something that feels like the freezer, this probably won't be the one for you. It was very breathable as well. The size was kind of snug for our queen size bed, but it definitely fit, and still worked perfectly fine, especially when you get your fitted sheet on top of it. Other than that, this topper is excellent! ... show more

Transformed the bed!
Color: Dark Gray Size: King
I'm honestly very impressed with this mattress topper's ability to transform a bed. We have a king mattress that has become relatively firm. I wanted to explore options before jumping straight into purchasing a new mattress, and I'm really glad I did. This mattress topper fluffed up nicely after tumble drying on low. When putting on the bed, the sides stretched and went over the corners with ease. I bought new sheets with it as well (which I ordered in "extra deep"), and the combination of these two has worked great. Nothing pops off the corners anymore; they are plenty big. This topper is so pillowy soft. It really did transform the mattress from firm and rather uninviting to now so cozy and cloud-like. It's made it difficult to leave the bed! I would absolutely purchase this again and highly recommend it. ... show more
