Who Says Pregnancy Pillows Are Just for Pregnancy?
Size: 57 Inch, Color: Light Grey, Size: 57 Inch, Color: Light Grey
I bought this pregnancy pillow even though I’m not pregnant, and I have zero regrets!
This thing is incredibly comfortable and provides support in all the right places. Whether I’m sleeping, reading, listening to an audiobook, or just relaxing in bed, it helps me get comfortable and stay comfortable.
I love being able to hug one side while supporting my back with the other. It feels like being surrounded by pillows without having to constantly rearrange them throughout the night.
The only downside is that it takes up a decent amount of bed space, but honestly, that’s a sacrifice I’m willing to make. My family may disagree. 😆
If you’re considering this pillow but aren’t pregnant, don’t let the name stop you. Comfort is for everyone!

Size: 57 Inch, Color: Light Grey, Size: 57 Inch, Color: Light Grey
this pillow is huge i’m 5’8 and it’s perfect, as soon as i laid down it relived pressure in my back, i get hot fast and you can feel the cooling silk like texture, it’s weighted aswell, as soon as i opened it, it fluffed up an it’s been about 2 hours since and it’s already huge, it says 24-48 hrs to fluff up fully but idk how much bigger it could get lol it’s definitely worth the few extra dollars

I must have for pregnant women! Definitely helps sleep and comfort for sleeping!!
Size: 57 Inch, Color: Light Grey, Size: 57 Inch, Color: Light Grey
I do love this pillow, it does take up a lot of space on my queen bed! But when I wrap my legs around the pillow, it gives me much relief on my back! It also has basically a built-in pillow so you don’t even need to use a pillow! I love that I was able to unzip the outer material and wash it! You can use it to sit up and support your back, and when the baby comes, you can use to help with feeding! sometimes I have to turn it completely on the other side if I want to turn over, it’s big!! heavy! Very soft! Not flat at all! Firmness is great! Height is great! I highly recommend! I’m also five months! i got it about 2 months ago!!

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.
