  • Awesome mattress topper
Color: White Size: King
I rarely leave a review but I wanted to say this is awesome. My bed is much more comfortable bc this is thick and plush and it's not hot! The fabric is very soft and I'm so glad it doesn't make me sleep hot.

  • Cooling and comfy!
Color: White Size: Queen
I never write reviews but I felt compelled to come here due to looking for a thick COOLING topper/pad for soooo long! After reading reviews on several, I was willing to try this one. It does exactly what it says. It’s thick enough. It’s cool and seems to stay cool through the night. There was no smell and it fit the mattress with extra stretch. I found it of very good quality and would definitely protect the mattress. ... show more

  • Comfort But Not Thick
Color: Black Size: Twin XL
It was good but not as thick as it looks, its nice to have something to sleep on besides a stiff mattress so its a win/win. If your looking for something thick, this is NOT it. If your looking for something soft and comfortable than yes.

  • Great for comfort!
Color: White Size: King
This mattress top is working wonders to make our bed so much more comfortable! The mattress itself is a bit hard but the topper really does the trick to make it softer but still firm enough. I'm going to buy another one soon!

  • Well made and very comfortable
Color: White Size: King
Using this on our super-thick, pillow top King size mattress. The corner pockets on this mattress topper are extra deep and have no problem fitting around the mattress. Really like how the padding in the topper is segregated into squares. That keeps the filling from moving around and clumping in one place. It's comfy as all get out. The only thing to look out for is this is very difficult to wash due to how large it is. We have a super-size front load washing machine and this basically doesn't fit inside with any room to squish around. Sure, you could cram it in there but then it's so tightly packed that the center of the wadded up topper won't even get wet. That is not a problem unique to this topper, but any in the king size, super-puffy range. Very happy with this product. It's our second one. Would buy again. ... show more

  • Not that great
Color: White Size: King
I guess for what I needed it for it’s not considered extra thick. I thought for sure. It was a topper not a mattress pad topper now it could’ve been me reading the description wrong but I’m not happy with it. It’s not what I expected. It’s kind of like it looks like a feather bed, but it’s not it’s a mattress topper that has a little bit of padding on it really. It fits the mattress well don’t know about heat retention. It doesn’t have any smell so that’s good so if you’re looking for something, that’s just a soft top but not thick this could be your product. ... show more

  • A very nice topper
Color: White Size: Queen
This is a really nice topper, thick and soft. I’m very pleased with it but wish that it was some way water resistant but that would probably give up the breathability. There was no odor on unpacking and I put it in my dryer for about 20 mins and it fluffed right up. I have slept well on it and would recommend it to others. ... show more

  • Just buy it.
Color: White Size: King
The instructions clearly say to place in dryer to fluff, unfortunately my dryer is too small to handle the king sized blanket. I did get it to fluff using my hands ✋️. Cooling feature is really nice, totally revived my old mattress. So comfy. Its like sleeping on a cloud.
