There was a great thread on comfy lit a few years ago, the list I saved from it is:
Montaigne - Essays
Eckermann - Conversations with Goethe
Leopardi - Zibaldone
Emerson - Essays, English Traits
La Fontaine - Fables
Plutarch - Moralia
Seneca - Essays
Robert Burton - The Anatomy of Melancholy
Sei Shōnagon - The Pillow Book
William Hazlitt - Table-talk
Coleridge - Table-talk, The Friend
Aulus Gellius - Attic Nights
Athenaeus - Deipnosophists
La Rochefoucauld - Maxims
Baltasar Gracian - Pocket Oracle
Yoshida Kenko - Essays in Idleness
Isaac Disraeli - The Curiosities of Literature
Pascal - Pensees
Landor - Imaginary Conversations
Charles Lamb - Essays of Elia
Joseph Addison, Richard Steele - The Spectator
That's probably an overwhelming list, but I can personally attest to Montaigne and Emerson being easy-going and edifying to read before bed.
