What do you want from us? I hate sectionals IMO the most expensive way to get the most uncomfortable seating.A sofa and 2 chairs are IMO a lot better choice . BTW if you want help here we need to see the space or at least a proper to scale floor plan of the space shoing windows doorways FP if there is one and also TV .

Just simply asking where can I look for a sectional that size without having one custom made? I’ve tried Bassett so far.

A quick Google search found your sized sectionals at Wayfair, Macy's, Living Spaces, Birchlane, Joss and Main, Crate and Barrel, and more....

Century Furniture

Cisco Brothers furniture

Those are still semi-custom, but make good quality pieces.

Google why didn’t I think of that. So far on those sites I haven’t found a sectional in exact dimensions I listed but will keep trying. But I would like to thank Chispa.

Hmmmm...a quick search of just Living Spaces came up with several options that are within 1" of your specifications

Yes, I would say just start looking at the different companies (they all have websites) listed above and you may find sectionals available within a couple of inches of your desired specs, which would certainly be less expensive, depending on the brand, than having one custom made. I love sectionals and just bought one from Macy’s during their Black Friday sale which was the right size I needed and didn’t break the bank. I had obsessed over the size since our living room is pretty small. Size is important, but not just length . If space is limited, then width, height, and general “bulkiness” are also important. I was considering a higher end, super comfy brand called Lovesac but it was just too big/bulky for my space. So, instead of spending 5000, I spent just a couple of thousand at Macy’s. The other fun thing you can do with a modular sectional is add to it, pretty easily! For example, I may swap out one of my end pieces for a chaise, in a couple of years. Don’t know if this is as easy to do with a custom made…. Good luck!
