Among the things that never fail to comfort me is a good reading armchair. Something comfortable, tall-backed to rest my head against, maybe an ottoman to go with it. Set it in a small, quiet corner with a good lamp and a small table to set a couple books and a cup of something on. Maybe next to a window that gets some sunlight with a view to pause and ponder between chapters.
Give me this and I will while away many contented hours.
