My best relief comes from using ‘a plush nest on the floor’ - sleeping on top of no more than one or two sleeping bags or a folded up comforter. When things are worst, I have a stack of folded bath towels to put between my knees and/or ankles when my legs are stacked on top of each other, or under ankles and knees or thigh by the groin if I feel the most comfortable sprawled out a bit. Or a towel under the bottom of my ribs to keep them from sinking down. I also play with the angle and height of neck/head/shoulder support, varying with the adjustable folding height of the towels.
On the worst nights, it really looks like a critter nest 
When I lived on a dorm, my father got me a plank of fat OSB and fat eggcarton foam.
Other than that, I refrain from couches and other overly plush seating and sit on NOTHING. EVER. with a ‘bucket seat’ or ‘sitting surface sloping down towards the back/backrest’. I fill the backwards slope up with (yet more!) towels - or a coat or sweater if I’m out somewhere - until it’s flat. I found the ‘slopes down towards back’ shape makes me put my weight on my sacrum more, rather than on my thighs and the ‘sit bones’.
Outside of that, I try to do a few reps of motions that help get the blood flowing to the areas that hurt worst, right before I go to sleep (hip circles, #4 stretch, shoulder rolls, etc). Not enough to get worked up before sleeping, but enough to ‘grease things up’ to help get into a stable comfortable position.
Even if ‘nesting’ is a bit too extreme for you, maybe trying towels or pillows to prop things up can help get you some better rest.
As for other furniture, aside from the completely flat chair, I usually sit on the floor on (who’d’ve guessed it, by now?) a folded towel or two. Because it’s hard, I move around a lot and don’t get extra stiff.
If we’re also talking non-‘furniture’ means for facilitating sleep with screaming joints, I have long and slow release melatonin that helps (slow release for normal days, fast and slow for days they scream loudest), and having magnesium with dinner and then about an hour before bed helps with the muscle tension.
I hope you get some satisfactory sleep in soon, through any means!
