Background

Neuronal Pentraxin 2 (NPTX2), also known as Neuronal Activity-Regulated Pentraxin (NARP), is a secreted protein predominantly expressed in neurons. It belongs to the pentraxin family and is rapidly induced by synaptic activity. Its primary function is at excitatory synapses, where it organizes the surface expression of AMPA-type glutamate receptors. By clustering these receptors, NPTX2 is crucial for strengthening synaptic connections and is a key mediator of homeostatic and experience-dependent plasticity. Dysregulation of NPTX2 is increasingly associated with various neurological disorders, including cognitive impairment, Alzheimer's disease, and schizophrenia.

Comfortable
Size: Queen Size
I was pleasantly surprised by how comfortable this latex pillow is! It provides just the right amount of support without feeling too firm, making it perfect for someone like me who prefers a balanced feel. Unlike memory foam pillows, which can sometimes feel too dense, this one offers a gentle bounce that adjusts to my head and neck naturally. One of the things I appreciate most is how well it maintains its shape throughout the night. No matter how I shift positions, it doesn’t flatten out or lose support. Another bonus is that it stays cool—I haven’t experienced any overheating, which is a common issue with other pillows I’ve tried. There was a faint latex scent when I first unboxed it, but after leaving it out to air for a short while, it completely disappeared. Overall, this pillow is a fantastic option for anyone looking for something supportive yet comfortable, and I’d definitely recommend it to others!

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.
