Our bedroom needs a renovation. We need to paint and buy a king-sized bed frame. (The mattress is currently on the floor.) We are also open to replacing the nightstands. Pretty much the only items we're committed to/stuck with are the grey-brown Hemnes dresser from Ikea, our new king-sized mattress, and the yellowish bamboo floors.

We are thinking about getting mid-century modern-style walnut bed frame, but we are ok with keeping the mattress on the floor for awhile because our toddler loves it. We need to pick a duvet cover so that we can decide on a paint color. We want:

1. An interesting print with at least a splash of color
2. Minimum 200 thread count
3. 100% cotton

Does anyone have any suggestions?
