First Graphene is on the Cusp of Innovation That's Second to None, page-40

Cover: 100% Polyester
Filling: 90% Polyurethane Memory Foam, 10% Graphene Fill
Weight: 1200gms (i.e. 120 gm per pillow)
Finish: Air flow mesh on gusset

Go for it boys.That's 120gm per pillow. a $15 bn total market and smart pillows about $ 4 bn . Just think - from $50 to $150 each, that could be 18,000 tonnes of graphene p.a., and if only 50% of the smart pillow market - 2,500 t.p.a!

Sadly, nothing like the good old days in 1890 when you could count on 3 lbs of goose feathers. (For the lb challenged that is 1,360 gms.)

Goose feathers from around a goose's back side or 120 gm of carbon black mixed in with cross-linked hydrocarbons.
What a choice.
