I have yet to form an opinion as of yet. The pillow is okay, but in my opinion could be thicker. It has a tendency to flatten out a bit much, but when incorporated over another pillow, it is very comfortable.
I got the ghost pillow only because it came for free with the mattress - nice special offer. Now it's the only pillow I use. Other reviews mention the smell, which is true. They add some scent, which isn't bad. It's faded over the past month or so. More importantly, it's so comfortable.
Bed was a little firm for me at first but has gradually seemed to soften a little, I like the bed alot over any spring mattress. My wife absolutely loves it and I wished it was a little softer . But overall the best mattress I've ever owned.
I am a pillow flipper, constantly turning it when it goes "flat" during the night. I have found the perfect amount of softness and firmness, and it "fluffs" back up quickly!
