So comfy
Size: King (Pack of 1), Style: Standard Loft (4" - 5")
I spent time looking up/watching videos on pillows for neck pain and this one comes up a lot. I’m someone that used to wake up every few weeks with a stiff neck so bad it could make me cry at work. I haven’t had that happen once after months of using this pillow. I look forward to laying my head down on it every night. It’s a luxury experience every time. I think what it does so well is maintain its shape. You can really squish it up how you want and it stays there even after hours. Moldable but somehow still firm. It’s expensive but to me the value is there because I no longer get crazy neck pain from sleep. Worth trying it out for sure. Btw I was stuck between this is and Purple brands couple top end options. I never got around to trying them because I tried this one first and was very satisfied!
Feb 2026. Still use it every night and it's still protecting me from neck pain I used to get from sleeping. It's held up amazing. Hope to use it for many more years.

Saatva Pillow is great
Size: Standard/Queen (Pack of 1), Style: Standard Loft (4" - 5")
So far this is the best pillow I have had in the last 10 years and I have tried two Purple pillows a couple different memory foam and Gel pillows at least 4 more pillows that I can't even remember the names of. My neck and shoulders are almost pain free. I have also been doing more stretching of my arms which is also helping, but this pillow has really made the most difference in the pain I have had, I felt difference from the first time I put my head on it. It's comfortable, the perfect height I got the 4"-5", I also got the queen size and it's great. It supports my head just right. I also ordered the Saatva Classic 14" mattress from the company and I sure hope it's as good or better would be great because I have back issues for the last 50 years.

Cotton Fluff Around a Mostly Empty Bag
Size: King (Pack of 1), Style: High Loft (6"-7")
Bought the high-loft king, thinking it would be a great (tall) side-sleeper. What I got? A very nice, completely compressible cotton outer shell wrapped around a bag a bit smaller than a standard pillow. In that bag? A tiny amount of small latex chunks, just about a third full. That’s right, some cotton fluff around a basically empty bag. Could you buy some latex yourself and add it? No, the bag is sewn shut. You could probably fill a small pillow with latex you bought elsewhere and put that in. But seriously, what did you pay Saatva for in that case?
Probably as close as I’ve seen a major/high-reputation company get towards a literal example of rip off.

Wrong item ships/decent pillow/price unjustified
Size: Standard/Queen (Pack of 1), Style: Standard Loft (4" - 5")
Sent me the wrong pillow twice in a row. It said high loft and standard loft on the packing, not sure what the problem is. I ordered standard loft both times, and both times they sent high loft. That name is very deceiving though. If what I have is high loft, the standard loft wouldn’t be much thicker than your standard flat down pillow. If you’d like any sort of neck support I’d suggest starting with the high loft and going down instead of the other way around. I am 5’ 7” 130lbs and this pillow does not lift my neck up further than neutral, which is a good thing. Shredded memory foam pillows are significantly higher or thicker if that helps.
Pillow itself grew on me. You can definitely feel that there is a different material in the center of the pillow. I ordered it as a gift and ended up keeping both pillows. The price tag on this item is absolutely outrageous. I would have never ordered it for myself. Saatva products don’t last in my experience, we got their firmest mattress and within 2 years it was sagging horribly. I am interested to see how long this pillow lasts!

Side sleeper- lost loft within 2 weeks
Size: Standard/Queen (Pack of 1), Style: High Loft (6"-7")
Side sleeper and within 2 weeks this pillow has lost its loft and has become lumpy. I have spent so much money trying to support my neck and shoulders, this unfortunately is not it. I will continue my search and return this one.
