    Sasstie Wedge Pillow
    Color: Cool Grey, Size: 24x24x12 inch
    Perfect. I used it when I was recovering from hip surgery. Relieved a lot of pain in my hip and knee at a time when I needed relief.

    comfortable and firm!!
    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.
