I promised I'd be back with another sectional design after my last video, so here we are! Let's build a the "sectional sectional" this time.

This design is simply two outdoor sofas that butt together in the corner. To achieve this design, I made it modular--so it's in three pieces: a corner chair plus two one armed sofas on each side.

In my last video, I shared a chaise sectional very similar to this: youtu.be/HcG0fZOO_Vc

But this one has some challenges with two angled backs meeting at the corner. I hope you enjoy watching me fumble my way through it!
