West elm, Hendredon, Michael Gold, Ethan Allen. Generally, unfortunately anything made with bonded leather is probably poorly constructed in terms of frame and materials (foam, padding, etc). Additionally bonded leather does not hold up at all.
Unmustashian, but I bought a Michael Gold sectional 17 years ago. It was maybe $3000. It has been through 2 kids, 4 moves, countless spills, cats, dogs, etc. it still feels good and, shockingly, looks good (tan upholstery). I even took the cushions apart and machine washed them and they still look good. One day I will have it recovered and it will continue to be a great sofa. It has down filled cushions and they are lovely and comfy.
Choose a neutral darkish color, non reclining, plain style (won't go out of fashion) and buy the best quality you can. Craigslist is often good for furniture. It's kind of like buying $150 shoes that last for years vs $20 shoes you have to replace twice a year.
