Seriously, cancel the sofa and delivery. I'll bet if you go back and look at the page from which you purchased it there will be a charge for assembly. I find that it is usually more than the cost of the furniture. Take my word for it, this is Friday, you can cancel it. Then you can take a nice deep breath and go to a furniture store that will deliver something preassembled. Or, you can look online at IKEA because anybody can put those together🫢😆
