I would suggest going armless so that people can get in/out.

No hard info, but I read how a decorator did one for her own home by having a full-length firm cushion made to set on top of the existing cushions, then slipcovering the whole thing. It looked wonderful and extremely inviting with the table and similarly sumptuous chairs gathered around.

Not all loveseats/sofas would work. You'd need to check seat height carefully. Below is a picture of my dining/library room which I just "created" recently (got rid of traditional dining room set). My loveseat is the Marcel Mini Sofa from Pottery Barn. I think it's 55" wide. It works perfectly with my table (and is the correct height), but it gets only occasional use, and no kids have used it yet! When I was looking for the right loveseat, I also looked an antique settees, many of which also had the right seat height.

You will need to plan on being able to let people sit down and then move the table close enough to them for comfortable eating! Nice look, but not too practical if you have a heavy table.

This is what we use. I have a folding table I set up over the trunk when we need to do it all as a dinning room. The trunk is not in the way. I use long table cloth to hide it all. Otherwise it is just couch and coffee table.That trunk top is work in progress, just started, mosaic.

We pull up the two Captains chairs up on the other side and I also have two other chairs I can set at the ends of the table if we need to seat 6.

See below for my inspiration picture. Nothing like I ended up with.Mine is the tacky version.

Cyn: In my pic above, the loveseat is not close to the table because most of the time, we're not using that room for eating. But when we do, we move the loveseat closer to the table, not the other way around.

I think it would be really cute. Just make sure the fabric is easy to clean because things do got spilled. Especially if you use the table daily. Even if you only use the chairs & the sofa is for look, things still spill over the sofa side

I would make a tight slipcover for the sofa. If your style is modern, maybe leather would be a good option.

Just a thought, instead of the usual sofa/loveseat, have you thought of getting a settee? they tend to sit higher than the usual sofas. I can see those working out really well w/ a dining table.

Lee Industries has some cute settee too and they can get slipcovers or even leather.

sueb has almost exactly the look I want. I'm fairly traditional (for now anyway) so I'd pictured a small rolled arm almost Chippendale style, but slightly more modren. Ethan Allen has a sofa called the Hartwell that could work if it was 14" shorter.

As far as fabric, I'll probably choose a sturdy microfiber or have it slipcoverd. I'd love a carmel-ly leather, but that's not in the budget.
Here's the nook sans new table and chairs, which will be here Christmas Eve! The narrowest part of the nook is 60".

I love the Lee settee, but that's $$$. I do like it alot.

have you checked out ballard designs-- our dining bench is from ballard design & it's quite comfortable.

this one is cute -- but only 51" wide. Don't know if it's too short for your table.

(there are more fabric on their site)

The table was a surprise present for DH and it arrived Xmas Eve. It's a 44x77" oval Copper from Arhaus.

I love the Ballard Designs sofa, but's it's too small. the table itself is 77" long, so 60-63" would be best. That makes the Marcel too small as well. I found one on Amazon that may work, but the seat is very low.

Any preferences or other places to look?

sueb, whatever works for you is great! For myself, moving the table would be easier and less strain on the back. My DH and I can move our 7-ft. pedestal dining table by ourselves, but I can't help move the sofas. I suppose a loveseat is easier, but then again, more difficult to slide in and out for some of us older folks once it is close enough to the table-of course, bear in mind that I am 5'4" amd 115 lbs, so I need to be sort of close to the table to be comfortable.
