I love this pillow. I did not have any trouble adjusting to it, it was completely comfortable to me from day one. It arrived well packaged in pristine condition. It's not just great for sleeping, it also makes a great neck rest turned backwards reading in bed. It is so great, it made it really obvious how worn out and terrible the old pillows had gotten so now I guess it is time to replace those too. Oops.Am happy with purchase. Would buy again.I hope this pillow would be exactly what I was looking for after reading all the reviews, watching the videos, spending time considering it etc but after sleeping on it (and having purchased extra pillowcases as it doesn't come with any) for over a week, in the correct position, which did not take much getting accustomed to for me as I've had to sleep on my back for the past 5 years due to having to have surgery, I found it impossible to use in any position without it crushing my ears, including lying on my back so I've had to go back to my old pillow with the ear indentations. That is ideal for not crushing your ears if you've had ear surgery or just get sore ears from lying on them but not for stopping face creasing so I'm sad I wasted all that money.
