Three feather pillows. Usually the two feather are under my head and one (the thickest) I kind of use when watching TV or cuddle up to sometimes. Usually don't take any to motels, but will take one along for use in the car or as an extra for when we're visiting our kids.

I could have sworn I posted this....

1 pillow under my head - foam (I am allergic to down). No, I never take it with me on vacation.

One fiber filled hypo type and the same for Mrs Coaster.......... but sometimes I just nestle into Mrs Coaster's... they're so warm and supple and she likes when I suck on the two of them! :D

I have yet to find the "right" pillow for my head & neck, & my chiropractor has x-rays to prove it. I've actually had to jury-rig a pillow to the headrest in my minivan for support while driving.
