The only one I can ever recall seeing commercially available is from IKEA, which has pull out shelves.

What style bedding are you drawn too? What is the wall colour? Inspiration: Black and white (or off-white) with deeper green accent pillow. Though this room is not carpeted , I thought this room would give example of how the colours and wood tone work together.

You already have the timber feature wall pic that first came to mind in your idea book :) Another elegant idea could be 3 or more padded fabric panels as in this pic https://www.houzz.com.au/photos/covenant-hills-contemporary-bedroom-orange-county-phvw-vp~1482108 The narrow individual pieces would increase fabric options and probably decrease cost of fabric. I've also seen padded walls or large panel (eg width to include bedside tables) in a neutral plain fabric and then a smaller actual bedhead in a contrasting bolder print.

Is that large picture attached to the wall, and if it is why not just hang it? Even if it is secured somehow it has a precarious vibe in what is meant to be a restful space.
