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.
