THEE BEST SLEEP!!! This has helped my hip and back pain immensely! I will be recommending to all my pregnant friends. Plus I can cuddle with my husband easily! I feel like I'm sleeping on a cloud! My hip and back pain are practically non-existent. I'm spreading the word to all my pregnant pals. Only downside: my husband keeps stealing it!! :))

She loved it! I got three different body pillows for my wife for Mother's and she chose this one to keep. She stated she loves the versatility to switch sides when she wanted. I’m happy with it as long as she’s happy with it. I just wish it came with a pillowcase, our normal queen-sized one doesnt really fit the pillow's shape

I really tried to get away with using regular pillows but they shift and I was sleeping terribly. I didn't want to buy a pregnancy pillow over fear of collecting too much stuff, but this set CHANGED MY LIFE. I could not recommend it more. I finally was sleeping through the night and I wasn't waking up in pain or in a pool of sweat!

If your having second thoughts on getting this, DON'T! GET IT! At 20 weeks pregnant I have been having alot of back pain due to no pillow support. I've had this for about 3 weeks and I've been having a better night sleep and feel more relief on my back and belly. 100% WOULD RECOMMEND, MY 1 YEAR OLD KEEPS STEALING IT AHHHHH!

I really love this pillow. I wish I had this instead of my big body pillow when I had my daughter 27 years ago. I recently had back surgery and my surgeon recommended this. said it would aid in the recovery process keeping my spine aligned and in one place. In florida i sleep really hot, but this pillow has this LatticeCool feature that helps a ton

I'm so happy I purchased this. It is the perfect size for me (I'm petite). I've not had any issues sleeping, in fact I sleep better! I love the shape of the pillow and how i can spoon it. I put it between my knees and wrap around it like a tree. I've already recommended it to others. Mind you, the the pillow is increinbly attractive and looks like it's from vogue

The best nights sleep I’ve had since being pregnant!!! I honestly don’t think I’d have been able to sleep safely without the pillows supporting my back and little bump 😍 I’m usually a front sleeper so really struggled to sleep well in my second trimester, I’m hoping this will really help as I approach my third trimester. Thank you Kiyo Pure! ❤️

Amazing product! There are so many pregnancy pillows out there, it is overwhelming to know what to get if you’ve never been pregnant before. I wanted something that didn’t take up my whole bed and kept me cool. (look at the LatticeCool foam!) This pillow has saved me. I went from tossing and turning all night to snoring!!!!
