Post a picture of the actual room and furniture

Not a pro. Just "food for thought":

If the room is small and your impression of it is dark, consider painting it all white or off white or another pale color. Lighter color for bedding with a pair of matching pillow shams would also lighten the room while making it feel more complete. On a full sized bed, you could choose a queen bed spread, preferably reversible, and it would likely cover the bed frame, too -- but you might need to stitch or pin up the bottom corners or tuck them under the mattress. Two extra shams that coordinate but not match -- two solids and either two different solid colors or two print could help complete the decorating look. If you like the mountain picture, see if you can choose a solid color from with that picture for your bedding and a second color for within the second pillow shams.

When you cannot have a pair of nightstands, you might consider a (bed width or a pair of smaller) box shelf -- a shelving board DIY project, with or without the back --

and you could certainly put art over box shelves unless your headboard is high.

In a small room, you might even consider not using a headboard or foot board ... just a metal frame with wheels/casters so it can be easily moved to enable you to walk around the bed to more easily make the bed.

Adding casters to your night stand(s) could help with them moving them for cleaning, too.

and an alarm clock and/or cell phones and charger -- things you'd ordinarily keep on your night stand.

Sometimes a floor lamp table combo might fit where a night stand would not -- but if you choose one, make sure it is heavy/sturdy enough not to easily tip over.

Choose mid-large white lamp shades to let out as much light as possible.

Take a close look at your night stands and see if they could be stacked (held together with a vertical board on the back of both the length/height of the backs of the stands) might be possible if the legs of one is removed and then they could be used for lingerie storage rather than as a night stand.

Over the inside of the bedroom door shoe racks might help with a place to store those.

Pics would be needed for more suggestions from the Houzz pros.

Avoid clutter. Clutter makes a small room look even smaller. If you need a place to store items such as in baskets or to display a few things, consider a top shelf above your bedroom door frame and all across that wall or other walls in the room with the shelving staying the same height all around the room. How deep you'd want the shelving would depend on the baskets you've found for storing stuff in. Such shelves could also hold small totes or duffel bags with items stored in them but matching baskets would likely create a better visual.

Whether or not you choose to add vertical cabinets/shelves beneath the high shelves would depend upon your space.

Know what space you will/could have before investing in baskets.

In a small bedroom, do not waste underbed storage space. Use covered bins for that, preferably with wheels to protect what is stored -- shoes, out of season clothes, blankets, etc., -- from dust.

If you don't have or want wheels on your bed frame or to enable your bed to be moved, then you could invest in bed risers and have more under bed storage space -- space for deeper containers.

Try to keep whatever you stored hidden within a container rather than displayed to avoid the look of clutter.

If the blue in your painting is medium or dark, you could still use a pale blue for your walls.

Hi Anna,

We came across your question and as fellow New Yorkers we know the struggle of space! We havent seen the space but we would recommend painting walls white (ie Benjamin Moore White Dove) to offset the rich wood in the existing furniture. The bed is minimal so we would do some minimal sconces, a light textured area rug, neutral bedding, and pull some color from the art piece for the lumbar decorative pillow. Finish it off with a big floor mirror to open up the space and for a real statement add a fun wallpaper on the ceiling! Hope this helps :)

Stay safe and well from the NYC designer duo,

Taylor + Yashlie
