I've had other foam pillows so I was expecting it to be more like them. I was wrong. My head sinks more into this pillow. My neck hurt for the first week using it and almost threw in the towel, but I quite like it now and I don't have any neck pain. The pillows have a scent to them, I learned that it was the lavender they mix in. The scent was very strong at first but has now died down quite a bit.
Purchased these pillows a few weeks ago and they are perfect. I have bought so many different pillows and fight with them all night. These pillows are exactly what the manufacturer states. Cool and shape you head and neck. Best purchase ever.
