Pillows are a tricky thing especially when ordering online. I read the reviews and, as always, there were some negative ones saying they are too flat, lost shape, etc. I took a chance because the majority really loved them and I have say they are a dream! I do not like medium to firm, but I also don't want them to be wafer thin. These were absolutely perfect right out of the bag. I put them in my pillow cases and they fit perfectly. I've now had them for a couple of weeks and they have still kept their shape and comfort. I sleep with two pillows, one for my head and the other for my side and both were fluffy enough you can sink into, but they also kept their integrity. An added bonus is they are a great price for two pillows. I will be ordering two more for my spare room.
