A good lamp changes a room faster than almost anything else, and you do not have to redo the furniture to feel it. I like to mix shapes: a round, glazed base next to something tall and thin. The striped Ravello lamp from TOV Furniture is a happy shock of green on a plain shelf, while the Interior Define Bellamy is the quiet one you put beside the sofa.

 

For tall corners, Castlery's Iris floor lamp has a wavy shade that softens a hard room, and the Ivy Bronx Paulson has a warm wood stem that works next to a bed. Over a table, the Mercer41 dome pendant and the 17 Stories brass arm lamp add light without taking up space. Look for warm bulbs and a dimmer, and keep the shades in cream, brass or glass so the pieces look like they belong together. I went deeper on a related idea in Floor Lamp Or Table Lamp.
