I have taken a few trips and I can say the NEW Travelrest - The Ultimate Memory Foam Travel Pillow is the best travel pillow I have used. I have used most travel pillows at one time or another. On my last trip to Europe I slept 6 hours. You do have to recline your seat to get the best performance from this pillow in my opinion. The back of it has a special design so it does not feel like it is pushing your head forward.
Also, I put in ear plugs and I slept real well. I paid for this pillow. I did not receive it under any promotions. The only flaw is the sack it comes in. Unless you are careful it can tear easily.
