memory foam pillows- love them-
I have 2 temper-pedic pillows and foam and down... I tried a My Pillow and returned it.
I think they might be washable.
My go-to pillow is a rolled up towel with a poly winter sock for a sleeve and that really works on my cranky neck. Neck bones work too but the rolled-up towel is a whole lot cheaper than a neck bone.
I have an original Tempurpedic memory foam pillow I got at Brookstone 20 years ago.
The thing weighs about 8 lbs!
IIRC it cost about $120 or $140 in 1998.
