What is memory foam? No tho, I had seen a replica... It is made of wood/jade depending on the status of the people using it I guess.. And then covered by garments and that's it? No cushiony feathers or cottons... So it's hard as a rock... But idk how ppl actually sleep on that? Maybe there were varieties
There was this story where the wife threw the pillow to husband in a fit of rage and the husband dodged it otherwise his skull will crack
How do ancient ppl not suffering from neck ache sleeping on those tall and hard pillows is beyond me. They were made of block of wood and sometimes even jade ╮( ̄▽ ̄)╭
