      Unreliable product be careful
      Size: King (Pack of 1), Size: King (Pack of 1)
      I bought this pillow and loved it. King size and firm. I bought another one and it is less firm and smaller in length (as seen here) and not at all to the quality onto first one. I’d be careful and check these if buying. Very disappointing experience

      A little misleading
      Size: King (Pack of 1)
      Overall, it is comfortable. However, I ordered a king sized which is 36" long, but this pillow is only 33". That's somewhere between a queen and kind size. Second, it is not a medium firm. It is more toward soft and lets the head drift down close to the mattress level Over time, you may have neck problems. Time will tell. Update: It is great! My neck feels better and I sleep better. There is still a little odor, but it's not a problem. I recommend this pillow.

      Solid and Firm, but not too Firm
      Size: Standard (Pack of 1)
      Great pillow, best I ever put my head against! Not too high, not too firm, do not recommend for stomach sleepers, but I am mostly a back sleeper. It is also heavy enough to support your head.

      ⭐️⭐️⭐️⭐️ Adjustable and Better Than Most I’ve Tried
      Size: Standard (Pack of 1)
      I’m a really tough pillow critic and have a hard time finding one I actually like. With that said, this pillow was better than a lot of others I’ve tried—mainly because you can remove some of the latex shavings to adjust the firmness. I ended up taking out about 20% (do it over a big trash can because the shavings can get messy!). When it arrived it was too firm for me, which is why I had to take some filling out. Even after adjusting it, it’s still not my absolute favorite pillow, but I do use it every night as a “hug” pillow and it works great for that. I think people who aren’t as picky as I am will probably really enjoy it, especially since you can customize the amount of latex to get it just right. I’d give it 3.5 stars, but rounded up to 4.

      Good Value Latex Pillow
      Size: Standard (Pack of 1)
      Most latex are horribly expensive and smell strongly. This pillow good for a side sleeper, little odor, med firm.
