Chair

BB&B chair is probably flimsy as hell. Doubt it’s any good at this price. 
Wondering if the Eames replicas are any good. 

I had a stressless chair but the back extended up past my head so I didn't like it for listening to music; I've since replaced that with a real Eames chair and ottoman, and while it sits just a tad lower than I'd prefer, the sound is much better for me than with the stressless. 

Yes the Stressles are expensive and there are a couple of reasons to get one.  The quality and comfort are excellent.  I currently have a home theater chair in my listening room.  It's too bulky and the most of these chairs have a back that is too high and comes above your ears.  The "Mayfair" large Stressless is perfect and my ear lobes when seated are about 39 inches above the floor and the back is at 38 inches. 

I too was wondering if a pass labs clone would be the same as the original. 

The Eames chair has been replicated over the past 60+ years for a reason?  Add the right small cushion for lumbar support if needed?  I've looked at the Stressless furniture in the past, but just can't justify the asking price.
