Stable closet wall without studs?

[Punto]

Hello, I'm not quite sure how to make this stable, any tips are welcome

I am building a wardrobe wall between two bedrooms with IKEA PAX wardrobes + a white wardrobe facing the hallway. They stand on a pedestal that is 60 cm built of 45x70 frames. I will also frame in the ceiling and around where I can.

My idea is to frame in the PAX wardrobes so they look like they are built into the wall. I was thinking of framing it by putting MDF or drywall on top and around the wardrobes, which is preferable?

Then on the backside use OSB board and screw into the wardrobes where I can. Since there are 3x 100 cm wardrobes, I'm not sure how stable it will be. Then put drywall on the OSB boards and screw cc 45 with smaller drywall screws, around 20mm if they exist and hold?

How would you do it in this case without framing a whole wall?

Grateful for answers.

Since it's two bedrooms, you should have a proper wall at the back. Is it a temporary solution so that you're hesitant to change the layout?

Hi, not a temporary solution, just so short on space that it's difficult to place studs behind the wardrobes, if I did, I would need to redo the base I built where the wardrobes stand to maybe put in a wall, but I still have trouble seeing if they will fit. Then I would have to take space from the doors, here's another picture.

Did something similar. 2 pax 100cm in one direction and 2 pax 60cm in the other direction. Framed around the wardrobes and also secured to the ceiling/side walls, sealed insulation around. Then only drywall on the backs, screwed into the frames. A bit tricky when my daughter wanted paintings on the wall, then I had to measure a bit to get the picture hook on the edge of the frame, otherwise the nail would have ended up inside the wardrobe.
Completely stable and once you've filled the wardrobes with textiles, you can't hear anything between them.

Very stable and when you fill with textiles in the wardrobes, you hear nothing in between.

ok nice thank you, did you use 120 or 90 cm wide plasterboards on the 100 cm wardrobes at the back?

The plasterboards remained. When the old masonite wardrobe was torn out. The boards were held together by several layers of wallpaper 😅. Then lots of glue on the back of the new frames and measured and screwed drywall screws into the sides of the new frames.

Seal all gaps. Even if there are clothes in the closets, the gaps will still let sound through.
Whether insulation and drywall or OSB and drywall are best from a sound perspective is for someone else to answer. Since it's a smaller area, Ultra Board won't be that expensive if you want to hang things up, and it's heavier so it probably dampens certain sounds better.
