Buy this one!
Size: 65 Inch, Color: Light Grey
This was a great buy! I looked through many many different options before buying and this one was the one I chose. Definitely a good choice. It keeps its shape and is cool to the touch which is amazing for a hot sleeper. It helps so much with my sore hips being 7 months pregnant. Fits great on my queen size bed with room still got my partner to sleep comfortably as well. Definitely recommend!

Great pregnancy pillow!!
Size: 57 Inch, Color: Light Grey
I LOVE this pillow. It arrived quickly and was packaged very well. It was pretty squished when it arrived, but fluffed up very quickly! I didn't notice any odor when I unpackaged it. Love that the cover can just zip off for easy cleaning. It's helped a ton with my hip pain this pregnancy. It stays pretty cool, especially when compared to my normal pillow. First night I had it was the best sleep I've had in a long time and I look forward to laying down with it. Only bummer is it takes up quite a lot of room on the bed. I don't mind, but I do feel bad for my husband who I share with lol.

good
This pregnancy pillow feels really comfortable and provides good support while sleeping. It is a bit bulky, so sometimes I switch back to my regular pillow, but overall, it still feels really good and helps me get more comfortable at night.

10 out of 10
Size: 57 Inch, Color: Light Grey
10 out of 10. Just got this in and I am finally sleeping at night. So soft, instant lower back relief, and fits well even on the couch.

Too firm throughout, but no support
Size: 57 Inch, Color: Light Yellow
I like the feel of the fabric but it's honestly not comfortable for me. The stuffing makes the pillow way too firm and I wake up with sore neck muscles. I do appreciate the body length, (I am 5'3) and it's comfortable for a little while, but not for the whole night. Especially because I have to get up multiple times to use the bathroom, and this pillow just gets in the way. I decided to just use three different pillows for my head, my legs and my arms/back at all different firmness so I get the support I need. If you are able to deal with the firmness of the pillow throughout, this might be a good option for you. I also ordered the cooling option and this does not help keep me cool at night. Even with the AC on and the fan running. It sleeps hot. I ended up storing it back in its vacuumed sealed bag and put it away.
