Most women and men need between eight and eight and a half hours of sleep a night to function properly throughout their lives. (Contrary to popular belief, humans don’t need less sleep as they age.)

A stylish dining room with cream walls and curtains and black carpet as perfect foil to an eclectic array of furniture. Many of the pieces are classics of their particular era, and demonstrate how old and new designs can be happily mixed together. The prototype chair in the foreground has yet to prove its staying power and was thought up by the flat’s occupant.
