I ordered this pillow and the Sobella because I didn't know the difference. This pillow flattens out and wings up on the ends. The other Westex pillow, the Sobella, is by far the superior pillow and is in fact superior to any other pillow I have slept on in a long time and I have slept on many. I have an entire bedroom full of pillows we can't sleep on. I highly recommended the Westex Sobella Gel pillow and I have put the link on Amazon to it below. Don't waste your money on this one.
