You have lots of choices. If you like elegant and understated, go with the cream that is in your drapes. I like how it will be the same horizontal plane as the stripes.

If you like color and want some fun, do the coral that is in the pillows to match the bed.

If you are more the traditional type, I would stain the bench to match the bed.

Or you can go with teal from the bedspread, because, who doesn't love teal?

Pretty room! And fyi, I LOVE my end of the bed bench. I use it all the time.

Great bench! It does look great as it is.
