Is there a window????

Thanks, Irene! There is a large window opposite of the headboard (not pictured).

You could add a new light fixture on a dimmer.

For wallpaper, the light pastel blues and light sage greens offer the visual effect of more space.

I was just thinking about light - is the ceiling light your only light source in the room? Is this a rental?

A small chandelier would add a lot! Even in a rental you can replace a ceiling light, provided that it's installed correctly with a junction box, which is probable (except in my house, where about half the lights are installed without junction boxes - no code enforcement when it was built). Just save the original fixture to reinstall when you move.

One that might be particularly nice is the Ramsele pendant lamp from Ikea, which is ingeniously self-dimming (pulling a cord makes it more open or more closed).

Also ideal for renting: peel-and-stick removable wallpaper, perhaps for the headboard wall. Something subtle like a faux grasscloth is what I would aim for, not a pronounced pattern.

How about this tailored bedspread? https://www.touchofclass.com/camden-classic-fitted-bedspread/p/O050-001/?kc=DMFPFS8&code=DMF05&color=Chocolate&size=Full%2021_DQ_%20Drop&tid=DMFPLA&gclid=Cj0KCQjw-uH6BRDQARIsAI3I-UcVwsZMW5td9oPmCZGfXc0UWle4IjEeh1hzuV7hTfC2ExYC9Oz-YiMaAo5HEALw_wcB

I did some updates to the bedroom and wanted to share my progress.

I'm planning on adding a shelf behind the bed that has some succulents and candles.

Very nice! And coooozy lol! What about wall sconces instead of shelving. You don’t want to bang you head every time you sit up

You can add plants and frames, candles... to the window sikk
