Couch is light, easy to build, comfortable enough.  The “adjustable” backrest is definitely a gimmick.  They don’t lock and immediately sink back down when you lean on the cushions. I’ll have to DIY something to hold them at height.  Otherwise, for the price,  this thing is worth it.  It’s HUGE so the modular design could easily make 2 couches or a couple separate lounge chairs.
