Buy a custom sectional from What A Room Furniture, Cococo Home or Clad Home. They will allow you to get a sectional that would be something that is 92-96" that will fit nicely against a 100" wall. You can then get a length that fits the other side with bumper chaise or a regular chaise. I personally got a What A Room and it has been one of the most comfortable sofas I've been on.

By power headrests, do you mean just slight adjustments, or the more modern looking ones that go all the way back, kind of like the Texline linked below? Texline: https://www.ashleyfurniture.com/p/texline_6-piece_power_reclining_sectional/APK-U59603P5.html My wife and I were recently in the market for the latter, because the collapsed height is more conducive to an open concept living room. There are a number of options from different brands, but they're almost all on the higher end of the price ranges you mentioned. We did find a couple of cheaper options from Living Spaces, but they are not sectionals: Lorenzo: https://www.livingspaces.com/pdp-lorenzo-ivory-power-reclining-sofa-261595 Talin: https://www.livingspaces.com/pdp-talin-power-reclining-sofa-wusb-110217?_br_psugg_q=talin+sofa&query=talin%20sofa We had more or less decided on the Lorenzo until someone just happened to post a used Talin for a really low price, so we went with that instead. They're similar in function, but the Lorenzo is leather, while the Talin is a really coarse fabric. I honestly don't love the fabric, but at the price we paid, I think it'll hold up reasonably well against kids/dogs without breaking my heart, and we had concerns regarding the quality of leather on the Lorenzo. One notable couch we saw that kind of towed the line between traditional and modern recliner styles is the Correze from Ashley: Correze: https://www.ashleyfurniture.com/p/correze_3-piece_power_reclining_sectional/APK-U942023P.html I was actually quite impressed with this one. Particularly when it comes to modern styles, Ashley is more known for copying other higher-end designs, but this one seemed fairly unique. I never did find one quite like this on any other site. The recline functionality is very similar to the Texline. However, the stitching and seat width are more reminiscent of traditional recliners, and it adds the wireless phone chargers, which may or may not be a suitable substitute for the center console depending on what your intended use was. As far as true quality, I don't think any of these are top quality. Good furniture is just very expensive. If you do more digging into any of the above models, you'll find that some of the framing is plywood, back and side "leather" are PU, etc. A good half or so of the floor models we saw for these had serious visible damage, which may just be user error or how long they've been on the floor, but still, that rate was significantly higher than for other designs we saw. Similar designs made with solid materials and good craftsmanship cost quite a bit more. As an example, here's a different brand's take on that Lorenzo with solid wood framing and all-top-grade leather, which costs more than twice the price of the one from Living Spaces: J&M Lorenzo: https://www.theclassyhome.com/Product/JNM-188241-S/JM+Furniture+Lorenzo+Blue+Grey+Leather+Sofa?g=t&msclkid=704de19689ab17aec05a829fc5cfc54c&utm_source=bing&utm_medium=cpc&utm_campaign=In%20Stock&utm_term=4578091611068670&utm_content=Ad%20group%20%231 Is it worth the difference? I don't know. Unfortunately, there are only so many showrooms in any given area, so a lot of it comes down to trying out what you can and reading reviews online. More on reddit.com

Not a specific recommendation, but in general, your local Costco club will typically have 1 or 2 models of power reclining sectionals in stock in the $1500-2500 range that are decent quality for the price. And if you do have any issues with it, Costco has an extremely liberal and long return policy. Plenty of "reputable" furniture manufacturers have items that look nice when they are new and are completely worn out after a year. At least with Costco, if it wears out in just a couple of years, you can take it back for a full refund. Also, something with a leather exterior will probably be a bit more stain and odor resistant than something with fabric. More on reddit.com

Have you looked into a modular sectional setup? I don't know if that'll help with your dimension issues but you're not as tied to whatever layout the manufacturer makes and can go a bit more custom. More on reddit.com
