I agree with PhoneLady. Why not have your headboard held against the wall by the weight of your bed without actually attaching it to the bed. Then, you could pull the bed out slightly and push the headboard aside to access the cubby. I use a standard metal frame for my mattress with an unattached headboard with no problem.

It is unfortunate you won't have one bedroom you can keep your present aesthetic. Yes, the side tables are too small but you have a repurposed look going and I think it works. Please leave the headboard as is, and if it can no longer be in your bedroom, well maybe a guest room? I think the window frames with mirror panes would improve their usefulness and help them make sense.

A fabric headboard (without a footboard so it doesn't feel too large) is by far the most versatile. It can work with any style and it's an updated look.

Hi, @bluemarble thanks for your comments :) Photo #1: I like looking at the happy pics on each side of the door, and the books on the bookshelf. Photo#2: I decided against the headboard cushions because I am getting an adjustable bed frame. Here are the lamps installed. I really like their practicality, and I am pleased with their look too :0: Now I am going to work on the exterior too if you want to have a look here ;)
