YNL Tension Curtain Rod No Drilling, 41-122 Inch Long Heavy Duty Shower Curtain Rod, One-Click Adjustable Tension Rods for Bathroom/Patio/Window, Outdoor Rods, Renter Friendly, Non-Slip, White

My stereo listening room has the exact same dimensions as your room. While I can drill into the ceiling, I hate doing so (thick plaster ceilings makes finding the joists rather difficult). The solution I plan to use for my ceiling cloud is a heavy duty tension rod, supported by the two side walls. The one I got on Amazon (linked below) is rated for 88lbs of support. I will be using two of them and hanging the panels using large S hooks. I have some fresh paint on the walls, so I'm letting them cure a bit more before trying out this approach. But I'd the rods support even half their quoted weight limit, I feel comfortable with this approach and thrilled to avoid drilling into my ceiling. https://a.co/d/04UpJGjy
