Mate I have not shot from my recliner yet but I do shoot out the front sliding doors off the dining room table right next to my lap top.
Normally I use a bi pod on a .22 rim fire. Once I did it with a 308 Win. The report near busted my ear drums.
I'll have to set up the recliner toward the front doors & shoot the 54 out through there. May haps I could even shoot prone off the sofa with a bit furniture moving. Just looking now, I think, if I put the sewing machine on the coffee table it will be the right height for a rest to shoot off the sofa.
Thinking I gotta pull the curtains way back & may be tie them so they dont catch alight. Might have to put something down on the carpet too so the falling embers & sparks don't catch light on it.
Oh yeah! wear ear protection.
Thanks for helping me think of that.
