Read this review. This pillow saved me.
Size: Standard/Queen (Pack of 1), Style: High Loft (6"-7")
I have to testify about this pillow, my brothers and sisters. Ever since I hit my 30s, my body has gone down. Aches and pains. Pops. Crackles. Snaps. It’s ridiculous. Over the last 2 years, I have managed to injure a muscle in my shoulder and the pain is unbearable when it is inflamed. I finally narrowed it down to the pillow I was sleeping on. I have an attachment to a pillow I’ve owned for over 20 years - that’s another story. I could fold it 3 times and it was finally thick enough to support my head. My shoulder got so tore up recently that I had to go through 2 rounds of steroids plus round the clock ibuprofen. Waking up in the night, the whole ordeal. I ordered this pillow after much research all over the internet. I was appalled by the $165 price ticket. But when you’re in that level of pain, you’re just about willing to do whatever it takes. The first night I immediately noticed I got more consecutive hours of sleep than I had in weeks. A week later and my shoulder is pain free. I could’ve cried. The height of this pillow stabilizes my neck and shoulders perfectly. It is firm, but gives and contours to your neck and head. It’s a heavy pillow but I don’t even care. Truly I don’t think I’ll ever go back. This pillow has saved my shoulder and I’ll never stop thanking God for it. If you’re experiencing back, shoulder, or neck pain and are considering this pillow, just order it. Please. Just do it. I’m forever changed. But I’m still keeping 20 year old pillow… just for sentimental purposes. 😂

Side sleeping pillow
Style: Standard - Medium
Great pillow for specific people. If you want a firm yet soft pillow for side sleeping then it works great. Not as good for back sleepers but it's very comforting and cooling.

Great therapeutic pillow
Style: King - Low
I have been having pinch nerve issues where my fingers fall asleep with the pillow I had, so I started to search for pillows that would alleviate that and stay within a budget. Although this pillow cost more than I wanted to spend, the only other pillow that I was considering cost $100 more than this Purple pillow, so I purchased this pillow. The neck pains and pinch nerve issues are mostly gone. It is comfortable, maintains its shape and keeps you cool. I hope this pillow lasts a few years.

This Pillow Is The Greatest!
Style: Standard - Tall
This pillow is amazing! It’s very pricey, but worth EVERY penny in both my opinion and my husband’s. My husband had been complaining about his old pillow for a while. I did some research and this pillow seemed to be the best of the best according to the reviews. But that price - yikes! I kept checking back and saw it was on sale and decided to take a chance. Bought it in the tall size (7.5 in.) and decided it would be his early birthday gift. The first night of him using it was AMAZING for both of us. He has snored like a freight train and will periodically stop breathing for 15-18 seconds throughout the night for the past 26 years that I know of. Immediately, his super loud snoring downgraded to a very low level of snoring. He said after the first night he fell asleep fast, did not wake up nearly as much and finally had no neck pain in the morning. He’s had it over a month now and says he can’t believe a pillow could make this big of a difference in his sleep quality. I can’t believe I don’t have to deal with his concert level snoring anymore. Plus, he no longer stops breathing for short intervals anymore! This pillow has been well worth the cost for us!

Great pillow, my neck is grateful!
Style: Standard - Tall
I am a combination sleeper and this pillow is comfortable in almost any direction I lay. Definitely a relief on my neck compared to my previous cervical type pillows.
