Very Comfortable and Good Quality
Size: Queen / 2 Packs, Color: White/Soft
These pillows are very comfortable and soft, but still give good support for sleeping. The material feels high quality and the size is perfect for my bed. I’ve been sleeping much better since I started using them. I would definitely recommend them.

Nice but smell when you open them
Size: Queen / 2 Packs, Color: White/Soft
These look nice and confirm the materials (no plastics no poly) but they do smell a bit - I am going to let them air out for a day and update this review if the smell goes away

Hotel-like comfort at home I bought these pillows from Beautyrest and they really exceeded my expectations. They are very soft but at the same time have good support, which helps you rest better throughout the night. They feel like luxury hotel pillows, especially because of their down-like filling. The jumbo size is perfect and they come well filled, they are not easily crushed. In addition, the cotton cover feels fresh and of good quality. They arrived quickly and well packed. After using them for several days, they maintain their shape and comfort. I definitely recommend them if you are looking to improve your rest without spending too much.
