La Z Boy has some nice ones, and they are so comfortable! They’ve gotten much nicer looking in recent years.

It sounds like you want an ergonomic sofa that looks like it would belong in a modern setting? I feel like sofas that have all of your comfort requirements are still going to be bulky and funny looking.

My decor style is modern. I have a bad back, so I put a small pillow behind me for lumbar support, and one behind my head when I want to "recline" (the sofa is against the wall). Or I scooch down until my head rests on the back, and put a really thick pillow under my back to support it. One sofa is a chaise style, and the other one has an ottoman for my feet. This has worked well for me while still having a nice looking couch. It's comfortable for me, even with my bad back.

This sofa from Room and Board is the nicest one I've ever seen, but honestly, I still think it's kind of odd looking from the side.

And I've seen other versions by a brand called Lorenzo. Room and Board is an extremely good brand, but I have no idea what Lorenzo is actually like.

@User you got me on point. thanks for wonderful suggestions.

It's always better to buy a sofa you have an opportunity to sit on before purchasing. Comfort is very individual. One of the things I focus on when purchasing because I think it really affects comfort is the seat depth. A lot of sofas are too deep for average sized people. Reclining adds another dimension to the decision. If you have an old sofa that is comfortable for you, measure it before you shop.

I actually really love deep sofas because I prefer to sit cross legged, or off to the side. Provide lots of pillows so anyone can sit more forward with their feet on the floor.

@Patricia Colwell Consulting they have some nice options. Thank you for sharing.

If the back of the sofa is tall enough to rest your head, I would not want fabric as upholstery.

I have had a non-reclining leather Stressless sofa and love seat for 25 years and it looks the same as the day we bought it. It's the most-used seating in the house. It has excellent lower back support.

If you don't want to spend a lot of money, IKEA offers the SLATORP sofa whose cushions can be moved around in various ways and includes a chaise. Scroll down to see photos of how it can be adjusted.
