Typically, you want some very thick berber type carpeting with thick quality oriented pad underneath.
Sell the leather and purchase a cloth sofa and/or chairs (cotton is nice and cool to the touch like leather). And clothe ottomans. Leather will reflect sound.
I sold my leather sofa for some cloth chairs and ottomans and noticed a decent improvement in the bass region. The cloth material and cushions certainly act as an absorber.
Cover any windows with soft/thick draperies. Maybe even some parts of walls.
Remove any wall pictures especially if they have glass fronts.
Install large bookcases (no doors, no glass) with not so nicely kept books on shelves. The less orderly the shelves, the better the defraction.
Get rid of any tables and floor or table lamps and install some recessed lighting.
Move the speakers away from side and back walls.
Ensure that your listening chair is at least 4 to 6 feet away from the wall behind it.
-IMO
