Highly recommended. This pillow is much better than memory foam. It supports your head and neck without being stiff. Out of the box it has a very strong lavender smell, but it dissipates to a nice level after a month or so. We haven't really noticed any cooling difference.
I have severe neck problems from two separate instances of whiplash and this is the first time in 35 years I have woken up without neck pain and the inevitable headaches that go with it. I also love the fact that the pillows don't get hot (even when I had a high fever from the flu!) and was very surprised by the lovely lavender scent. I honestly can't stand lavender but this scent is fresh and adds a soothing quality to the pillows. Even my dogs love it!! I hope to get the mattress soon too in order to help my lower back issues, I figure that if the pillows are this good, the mattress HAS to be even better!
I'd been looking for a good pillow for quite a while, because I get migraines frequently. I needed something supportive, but not super hard. I saw a groupon for the Ghost Pillow and it was the best decision ever. I absolutely love this pillow. It's supportive, so my neck isn't strained at all--which means fewer migraines--but it's not too hard, like a lot of memory foam pillows are. The one detractor is that the pillow came scented--lavender, I think. I'm sure for most people that's fine...but it gave me a migraine for two days. I couldn't actually use the pillow until it had aired out, and the scent mellowed a lot. But otherwise it's great.
