Background
Carcinoembryonic antigen-related cell adhesion molecule 1 (CEACAM1) is a type I transmembrane glycoprotein and a member of the CEA family. The extracellular domain of CEACAM1 consists of a membrane-distal immunoglobulin (Ig)V-like N-region and variable numbers of alternating IgC1- and IgC2-like proximal regions. Therefore, this molecule is also classified as a member of the Ig supergene family. Several hetero ligands for the N-domain of CEACAM1 have been reported. However, homophilic ligation of the N-domains of CEACAM1 with another N-domain of CEACAM1 is the predominant means of physiologic interaction. CEACAM1 has been reported to be involved in several functions such as tumor growth, angiogenesis, endocrine function and immunology in humans and rodents.

how good the product is
Item Package Quantity: 4, Size: Standard
These pillows are soft, fluffy, and surprisingly supportive for the price. They’re comfortable no matter how you sleep — whether on your side, back, or stomach — and they maintain their shape well overnight without going flat. The fabric cover feels smooth and breathable, keeping things cool through the night.
After a few days of fluffing and use, they settle nicely into a perfect medium firmness. They also wash and dry easily without clumping.
Overall, a great‑value pillow set that offers comfort, versatility, and quality — ideal if you need an affordable yet cozy bedding refresh.

Firm and comfortable
Item Package Quantity: 2, Size: Standard
These pillows are well made. Firm, yet comfortable. I am pretty rough with my pillows. I toss and turn frequently. After one year, they are still holding up.

Quite good. I am actually surprised. Too small for queensize
Item Package Quantity: 2, Size: Queen
These pillows are actually good. After reading a ton of reviews I pulled the trigger on these. I was 100% sure I was going to receive bad quality pillows (too flat or too thick). They do take 24-48 hours to firmen up. Let's see if they flatten out in a few weeks or if they hold up. My wife said the pillow was too thick and it raised her head too much. I don't agree, I sleep perfect on these, no neck pain in the morning.
Update 04/24
These are actually quite small to be considered queen pillows. They have become firm over the last few days.

These Euro size pillow inserts are fantastic! They’re soft, full, fluffy, and hold their shape very well. The firmness is perfect — supportive without feeling too hard. They filled my pillow covers beautifully and made the bed look much more luxurious. Great quality for the price and very comfortable for lounging or sleeping. Very happy with this purchase!
