Maybe the layers help.
Sorry my workflow is a bit old school.
1. Make a selection of the lower part of the bed. Copy/paste it on a new layer. Flip it vertically. Duplicate this layer.
2. On one layer delete the left half , on the other layer delete the right half.
3. The difficult part is to distort the left partition and the right partition exactly in the same way, so they still join in the center.
4. I added gaussian blur to both partitions.
The rest you can see on the screenshot.
