Good purchase!!
Color: Blue(one-sided Cooling), Size: 20"x54"(Pack of 1)
It’s so comfortable!! Perfect cooling, soft to the touch, perfect length (I’m 5’4) it’s fluffy and firm. There is a little weight to it but still very nice!!

Great for hot 🥵 sleepers!!
Color: Blue(one-sided Cooling), Size: 20"x54"(Pack of 1)
I absolutely love this body pillow!!! It is a nice looking pillow, silky on the cooling side and comfy on the bamboo side. The size is perfect and it really is cooling for someone like me that is menopausal and sleeps very hot 🥵🥵🥵 It keeps me comfortable all night.. I like the amount of fill inside the pillow. As a side sleeper with back pain the thickness of the memory foam keeps my spine aligned perfectly and doesn't flatten out. Best purchase I've made for cooling comfort at a decent price point!!

Nice and adjustable by removing stuffing
Color: Blue(one-sided Cooling), Size: 20"x54"(Pack of 1), Color: Blue(one-sided Cooling), Size: 20"x54"(Pack of 1)
I really like this pillow.
It fluffs up huge, and you can throw it in the dryer to fluff it up faster.
It’s soft, cozy, and cooling with the cool side of the cover.
What I really love about it though is you can remove stuffing easily to adjust the size and weight. It’s pretty big and heavy.
It was a bit too puffy and heavy for my taste so I removed a garbage bags worth of stuffing and now it’s perfect!!
Great body pillow I totally recommend.

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.
