I bought these pillows after seeing a blog article about how to tell if your pillows are too old or not (if you fold them in half and they don't open back up by themselves then they need to be replaced). Mine were ancient! I bought these hoping they would help with my bedtime asthma and they made a huge difference! I used to have an asthma attack nearly every night when getting into bed but after getting these pillows (and putting a cover over the mattress and washing all the bedding in very hot water) my nightly asthma attacks all but disappeared. They are so soft and comfy while providing plenty of support. I plan to get more for the guest room.
