I'm having trouble posting my question and it had multiple images so I'm going to split is up into 2 questions to see if it will post.

First question is how to fit the bed.

I have a small room 12x12. then a wall of closets on one side. One monster dresser at the end of the bed, and its the only wall that is long enough to hold the piece. It is a corner room so one modest sized window on each wall at the corner. My style is traditional. I have the room freshly painted, curtained, with new hardwood floor laid down. Love the simple color palette. But I can't get the bed right. I have a coverlet that I adore and want to get it coordinated with the fitting of the other bedding and bed frame. The current headboard is a cheap one I got from Wayfair last spring. I like it because it adds structure to the room, but isn't too heavy. It is not beefy enough to lean against for reading, which I'd like to be able to do, so a wood bed with headboard might be needed.

Just finished walls, curtains, and floor, moving back into room:

Latex bed in place, and I love it:

My main problem is the box spring is showing, and I am having trouble figuring out how to make a nice transition from different parts of the bed, to the room, and to the floor. How does one get the bed trimmed out for coordination with the bedding? I don't want to be too rigid in my details, so that I can be flexible with the covers for seasonal needs. I've considered getting a new bed frame with wood sides to partially hide the box. I bought this 8" box to go with my latex bed when I probably should have got a 5". But I have always had the taller boxes with past spring mattresses.

Room set up, but not the bedding I'm ultimately using, but you see the situation of the box spring showing and being ugly, as well as the steel frame showing:

This is my beautiful coverlet below. It has an off white background with light greenish blue paisley. The bed skirt on the right is white and too bright. the skirt on the left is a linen sheet that I hand gathered to see the look. I like this look. I know some people don't like skirts but I need something to fix this. I have 3 of these linen sheets that I could cut up and make a bed skirt. I recently bought a linen bedskirt but the gathers aren't as deep as this example below, and I like the deep gather.

My mattress is latex and very heavy. I was thinking of just pinning the skirting around the box. If I use an already made skirt, I'd cut it apart so I could pin it around the box and not run the lining between the box and mattress. This is why I don't want to use a fitted sheet on the box as a detail option, because it would be a bear to change out for cleaning. I think the skirt also fits with the room style.

What do you think for the skirting and options for resolving this transition issue?
