I've gone through so many pillows looking for the right one. I like a good balance of softness and thickness for support, and have never found the perfect combination until now. I've had it for about a month now, and it hasn't gone flat at all. Perfect for side sleeping and stomach sleeping. I haven't even tried the hard side yet because the soft side is so perfect. And sliding my arm into the middle while I sleep is so comfortable. Goes perfect with our purple 3 mattress and adjustable base.
