If your sofa has a pair of seats divided by a center console, lift each individual seat and console back out of its housing.
You’ll probably need Robertson drive bits, as base bars are often secured with square Robertson screws.
If you’re unsure about your mechanical abilities, you could take pictures at each step of disassembly to guide you during reassembly.
Label your disassembled parts so you’ll know where to reinstall “left seat back” and “top base bar. ”
After securing the top bar, drive the screws into the remaining bars to reassemble the sofa base.
