Toilets make a great bass trap. They are customizable too - depending where you sit and/or the fluid/solid levels you can tune them for the best sound. The only drawback is fitting the rest of your gear in the toilet - usually the door won’t close - audio is frustrating.
Seriously for good bass trap you need at least three if not four GIK corner traps. A large smooth leather sofa will be best. Cloth will absorb too much highs relative to lows.
