What is best under the Tromsø bed 90x200?

Our son wants a seat where he can sometimes watch a movie with his friend.

Now I have the white Ikea PS cabinet under the bed on the ladder side, and opposite it there should actually be a small seating area. However, I'm worried that the distance from the TV to the seat will be too short.

But I don't have a free wall where I could put the TV cabinet now.

Do you have an idea how I can best solve this?

Just putting the cabinet in the middle of the room looks dumb.

I really like the PS sleeper chair and since it’s not very wide, it would fit perfectly under the bed because the bed is only 90 cm wide.

But what does it look like if the chair is under the bed on the left and the PS cabinet with TV is under the bed on the right?

Too cramped?

I’m so unsure...

The bed and the PS cabinet already exist, only something to sit on is still missing.

But how do I best solve this?

How have you solved it under your loft bed?

Ideally, I would like to have a bigger sofa underneath and then just the TV opposite the bed. That would be the best, but unfortunately not possible due to space reasons :(
