I had a buckwheat pillow once and it was kind of crap. Honestly it doesn't really matter what you get if they're comfortable. You just got to replace them regularly. Like once a year. Washing them can help with allergy issues, but that foam is never going to return to its original state no matter how well you wash and dry it. You could always try getting something more organic so that you don't end up filling a landfill with foam all the time, but I mean we're already scrotum deep in microplastics (look it up) so I don't know if it matters at this point.

I use a buckwheat pillow with a mulberry silk pillow case. I live in Miami and I like a cold pillow, and that's the coldest combination I could come up with. they also have those blue gel cooling pillows, they're pretty uncomfortable, but I keep one under my buckwheat pillow, also in a silk pillowcase, so that I can flip my buckwheat pillow and the cool gel can draw the heat off so the other side is always cool for me. and silk pillowcases work a lot better than satin

I have a buckwheat pillow. I find it extremely comfortable, it reduced my neck pain. It is hard, but molds to the shape of your neck in a very comfortable way. It doesnt get lumoy in the same way a traditional pillow does.I have replaced it once now, first set lasted about 2 years. I personally greatly value that it is renewable material. The up front is kinda high, but the cost to replace the stuffing is low. I think it'll be comparable to a cheap regular pillow after one more replacement, which I think it's definitely durable enough to get to I also bet im paying a but more for hulls than i needed if i was willing to shop around. It's also cool cause you can clean the pillow itself quite easily by just emptying the hulls out. It stays cooler than a standard pillow.

For downsides, it is like sleeping on a beanbag. I've heard some say it's "loud" in that your ear is pressed right up against it and you can hear the hulls(?) Move around if you move, nit a problem for me, but people with sensory issues beware. I found that the grain made a texture that overtime annoyed my cheek, but a second pillow case was enough to fix that problem for me. It's quite heavy, I like this because it neans it moves less, but my wife finds it annoying.

I got one, had my wife get one after trying mine and I'm thinking of a gettibg a 3rd at some point. I got mine from comfy comfy and I would recommend their contour version as it seems to keep the hulls distributed more evenly than the standard.

I've tried feather down pillows and 🤧
