The Best Pillow for Side Sleepers Currently? Recommendation
I have the original Purple one. It’s a rectangle. Best for side sleeping. It has a couple inserts so you can subtly adjust the height to be perfect for you. Haven’t had a kink in my neck since getting that pillow3 years ago.

Try the Purple Harmony high loft. I have the low loft and I love it. My wife has the high loft. We've had them for about 4 years and it checks your boxes.

I have the Purple Harmony king size pillow and it is awesome. My wife has the Purple Harmony standard size. We've had them for about 4 years, no complaints. If you only side sleep I would recommend one of their pillows that have the inserts you can use to make it taller or shorter. They have gone up in price a good bit, but so has everything else too. The pattern you get on your face while taking a nap is hilarious.

The purple pillow. The grid one. It’s expensive but I wish I would’ve had one years ago.

Been using the Purple Harmony for about 8 months now and can confirm it's actually worth the hype - zero flattening and stays cool all night which was huge for me since I'm a furnace when I sleep

By “heavy” I meant primarily a side sleeper. I took a sleep test (polysomnogram) to help diagnose a sleep disorder. One of the insights from the test was how much time I spent sleeping on in different positions: for me it was mostly the right side (61%), followed by prone (stomach), and supine (back). I went with the med height version of their pillow. I don’t believe the heights have a different firmness level. I have the travel version of the harmony pillow and I think it’s similar in firmness to the king size I purchased. But for your concerns you may want to test both heights out to see if one makes a difference. You can always use the other as a knee pillow.

I had the coop pillow, but the purple harmony medium pillow is way better. So much more comfortable for my neck. Coop was too dense and who really wants to make nightly adjustments to their pillow until it is perfect? Not me.

I love my harmony pillow and I am a heavy side sleeper. I purchased the mid height but could have gone for the high version.

I had the slab as well, it was probably the heaviest pillow I’ve ever owned. I didn’t love it tbh. I like the harmony more.

Purple harmony, not the purple regular. I swear by it and have bought it a few times. There’s a travel edition too which makes my hotel sleep perfect, no more flat pillows anymore.

I have tried almost every pillow on this list, and hands down BIFL is Purple Harmony pillow. I’m a side sleeper and sleep hot. Before Purple I was flipping over my pillow multiple times a night, refluffing (especially Coop),and waking up with pain. Not with the Purple Harmony. It is a game changer. I sleep cool because of its honey comb design that constantly dissipates heat. No memory foam BS with “cooling gel” that will eventually saturate and be warm at 2 am. It also NEVER goes flat. It’s been over a year and I’ve seen no difference in height. My neck feels good when I wake up! The final kicker… my SO is a side/stomach sleeper that runs hot. He’s also a cheap male lol. After we tried them randomly in a store while my mom was mattress shopping, he was so impressed he bought the Purple Harmony low profile version while I got the normal loft version. He loves it! Get Purple Harmony (normal loft height unless you’re larger sized). I buy them for my loved ones and recommend them to everyone.

I’ve gone through a ton of pillows and the one that has worked the best for me is the Purple Harmony Latex pillow.

This. I’ve tried all the shredded latex pillows. While they’re great at first, if you move at all, you’ll be reshaping them or flipping them all night. I’m on my second purple harmony pillow (I like the low loft) and it’s the best I’ve found. I had to replace the first one after 3ish years as the grid did break down a bit. But I love it.

What’s a purchase that’s not fun, not flashy but now you swear by it?
I love my Purple Harmony. I'm usually a side sleeper, so I have a "tall" one that keeps my head aligned correctly, plus a standard one for when I occasionally sleep on my back (or when my girlfriend sleeps over).

Ever Bought Something That Quietly Changed You?
Purple Harmony Pillow in tall. Best pillow in existence. I used to buy new pillows all the time but they would go flat so fast. This is worth every penny. In fact, my husband bought a second one for himself because he wanted the tall version, and he initially bought the regular one. I highly recommend them to anyone who wants a great pillow. We have had them for years now,and they haven’t gone flat. Any time I can take it in a trip (namely road trips), I will. I even had it at the hospital when I gave birth recently. They make a travel version now, and I soooo want it for future air travel so I can have one in even more trips. This pillow is incredible. Definitely life-changing.

Buckwheat pillows are terrible
I personally use the Purple Harmony king size, tall. I like a higher pillow, but they have three height sizes to choose from.
