Cat doesn’t use hammock or bridge- placement suggestions?

Here’s the layout. Any suggestions for rearranging or adding to it? My cat never uses the hammock or the bridge and mainly uses the steps up from couch to bed. He’s an anxious, clumsy, big orange guy and the bridge is scary for him I think because it moves. Maybe one side should go up to create movement up for him to use? The hammock he’ll only go into if I use treats to guide him there. Do you think it is too high or that there isn’t a close enough step nearby? Should I put it in the open space to the lower left? He loves the bed so I know it’s not because it’s mounted to the wall. I think he’d love the hammock if he gave it a shot for more than the 10 seconds it takes to eat his Temptations.

Included cat tax of my sweet boy which also shows the scale.
