Nice Firm
Color: Blue(one-sided Cooling), Size: 20"x54"(Pack of 1)
So I don’t love this body pillow but I do like it. This is a great pillow for anything the only downside is that it’s super heavy. It’s not something you would throw around the house that’s for sure but it does do its job when I’m sleeping and need something in between my legs my knees. It’s nice and firm not floppy, it’s perfect for a body. It’s perfect height, I’m 5’4 so it is perfect length wise. If you’re looking for something fluffy and lightweight I wouldn’t suggest this pillow but if you’re looking for something you can use for say menstrual cramps or a bad back and simply just to have between your legs than this is the pillow you want. I recommend it to anyone who doesn’t mind a little weight while making your bed. I give it 8:10.

Love this pillow!
Color: Blue(one-sided Cooling), Size: 20"x54"(Pack of 1)
Love this pillow. I bought 2. No weird smell and the cover is half cooling and half bamboo. It is also removable so that it can be washed. The inner pillow insert has a thin permanent cover on it to keep the shredded memory foam enclosed, this is standard compared to other memory foam pillows I've bought in the past. I got them on a used like new discount, and they were still vaccum sealed and truly like new. I couldn't be happier with these pillows, I am so glad I got 2.

So Comfy
Color: Blue(one-sided Cooling), Size: 20"x54"(Pack of 1)
I'm obsessed with this pillow. Been looking for a good body pillow but could only find the kinds that have that polyester filled from the stores and usually they flatten out easily. But found this out and its filled with memory foam and the casing has a nice cotton feel and the other side is a cooling side which I love. Its so comfortable and can easy be reshaped back from the memory foam. It's worth it.

Wish it was more “cooling”
Color: Blue(one-sided Cooling), Size: 20"x54"(Pack of 1)
The pillow is somewhat comfortable, I don’t find it “cooling” it does hold its shape and it gets really fluffy. I am a hot sleeper I was hoping it would help with the cooling but I find it no different than any of the other body pillow’s I have bought
