Being it's a platform only bed gives you so many options. Great start! Houzzers will chime in with tons of ideas. Here are a few of mine.:

You could invest in mid-century pieces that you can keep forever. Shop around; these pieces are from just one of the many shops on etsy.

You could go Campaign style. This piece is from Birch Lane.

Love this Art Deco look from English Elm paired with a killer duvet from Williams Sonoma.

I like that there is no headboard. You are free to do anything you want for over the bed.

Wanted to add I am putting my surfboard over bed as a head board...Also, I really not too keen on the mid century modern pegs on most furniture.

Amber, the surfboard is the inspiration to your decor. You should have mentioned something so important to your scheme in your post.
