My sister works for a mattress retailer and she gave DH & I these really nice pillows for Christmas. I don't know the brand, but they are a core of down & feathers, with an envelope of memory foam over that. They're really heavy and feel very firm to the hand, but my head sinks in very comfortably. It's perfect for sleeping on my back. I keep a second pillow for side-sleeping; it's an older down pillow that is about half-empty now, but it wads up just the way I want it to, to tuck between my neck/head/shoulder. I'm not supposed to sleep on my side anymore (back problems) but sometimes I lay on my side awhile to get drowsy before switching to my back. It's not perfect but it works.
