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.

Full, Fluffy & Perfectly Supportive Euro Pillows!

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!

amazing.

Item Package Quantity: 4, Size: Queen

WOW. I was really skeptical, but the other reviews are spot on: these are amazing firm pillows. I really hope they don't lose their firmness and become lumpy like other pillows tend to do. Excellent pillows for the price!!
