How to Salvage a Space with Slanted Ceilings

Living in a french flat in a house in Strasbourg, we had some sloped ceilings in both our top floors. The living room was fine. The upstairs bedrooms were - interesting. We did have storage against the walls, so that did help out. The bathroom was quite awkward on one side - fine for a bath but you couldn't stand straight up. So my husband would shower in the lower bathroom instead.
Glad I don't have to deal with them now...

We have this massive master suite (it's the total area above the oversized two-car garage), but the slanted wall is only on one side of it. We tried the bed in several places around the room over the last several years, and finally, after looking at this ideabook, put it up against the slanted wall. The tall headboard (which is a bookshelf headboard) sits against the slant, keeping it stable so we can sit up in bed, but it leaves an empty space behind for storage for items we don't use--like extra pillows, heavy winter comforters and blankets during summertime, etc. It's the best solution I've found so far. Now I just need to figure out what to do with the other half of the room. It looks pretty but we NEVER use it. There are big chairs and lamps and stuff and it's comfy-looking but we never use it. I wonder what else I could put in there.

The problem with beds and slanted ceilings (pic 4) is making them! My one bdrm has ceilings that go all the way to the floor. Before I moved the bed under the window (not ideal, but better), it was a pain in the back trying to make that one side. I've been getting flashes of ideas going through the Houzz stories. Creating a fabric wall four feet high and putting the bed against it? I'd have to create a headboard to keep the pillows in place. How to keep the headboard in place? Keep the fabric wall, ditch the headboard against it idea. First order of business: get rid of the detritus filling up both corners. Off to my favorite consignment shop with my tape measure!
