Finally, a great pillow!
Size: Standard (Mid Loft), Number of Items: 1
Finally! After so much wasted money on sooooo many pillows, I come across this beauty! This pillow is amazing! I got the medium one, and it’s so perfect. Soft, yet supportive. I’m still surprised at how much I love it!

LOVE IT !
Size: Queen (Mid Loft), Number of Items: 1
I love this pillow. It is just right, firm enough yet soft. My head sinks in and is very comfortable. When I lift my head, the pillow bounces right back into shape. If it lasts, I will buy my family each a pillow as it is wonderful. I woke up with zero neck pain as I typically did when using a standard foam pillow. There is a very light scent yet when I covered the pillow with a protector casing and then a cotton case, there was zero scent. I highly recommend. Especially when compared to the comfort of a very expensive latex pillow my husband uses.

Dream pillow
I’ve been using latex pillows for over 30 years, and I can’t find them in local stores anymore. I’ve been needing to replace my pillow and finally decided to try this one. There are so many options on Amazon that it’s overwhelming. But this standard low loft pillow ended up being PERFECT. It feels amazing and just like the pillows I’ve been using since childhood. It is soft but cradles my head and neck perfectly. For me, it’s like sleeping on a gentle cloud. Very happy with my purchase. (Yes, it does have a slight latex odor. That is normal due to the material. It’s not very strong and it doesn’t bother me).

Great latex pillow
Size: Queen (Mid Loft), Number of Items: 1
This review is for the biamktp queen pillow. Medium firmness. Finally a latex pillow worth keeping. After trying many other latex pillows I'm finally sleeping comfortably. This pillow is soft, yet firm enough to give your head support. I'm not having any neck or shoulder pain when I wake up. I'm sleep on my side about 95% of the time. 5% on my back. I've been sleeping with this pillow for about 10 days and still am happy with it. It was delivered on time, absolutely no odor and it has a removable cover. I highly recommend it.
