My Flexsteel sectional has metal clips so the two pieces hook together. It's on a wood floor but it's against two walls so it's not going anywhere (it also weighs a ton). No recliners; we plan on a cat sometime soon and I once injured a cat by trapping it under the recliner when I closed it up, so I swore I would never own a recliner again. We did choose to use a larger coffee table because we needed the surface space, and the coffee table that had fit the regular couch just fine was too small for the sectional, both visually and functionally. Regarding measurements, our sectional sits in a corner against two walls. I simply measured the two walls and allowed a bit of space for small end tables, then hunted down a sectional that fit those measurements and wasn't too bulky for the room. Small-scale sectionals that aren't just two loveseats stuck together or a couch with a chaise stuck on (I find it very difficult to get out of the chaise) are not easy to find, but they're not ALL ginormous! Ours is something like 90" on one side of the "L" and 110" on the other. If you plan to "float" your sectional, get a roll of blue painter's tape and map out where your sectional's going to go, right on the floor with the tape, until the proportion looks right and then measure that; if you have the standard sofa-loveseat combo now you can shove them together into that space and get a rough idea of scale. The biggest "pros" in our house are that it wastes no space in our small living room - when we had a couch and loveseat, there was a substantial area in the corner that was wasted (furniture arms take up a lot of space) and we couldn't both stretch out to watch TV, read or nap while now we can and still have room for the dog. :-) The main con is that it IS a little bit heavy-looking for the small room, although cut-back arms, a relatively low back, and a slightly-bland midtone sage color do reduce the visual weight somewhat.

Just to update, we finally ordered a sectional from Century. It is L shaped with a loveseat on one wall and a sofa length on the other. The good thing is that it is 43" deep so it should be very comfortable to lay on. We chose a chenille type fabric in a greenish tone. We started the room's decor off by picking 2 oriental rugs and pulling colors from that. The sofa comes with 7 throw pillows, so I chose 2 different fabrics for 4 of those. We'll see if it works or not when it comes in! On another note, once we started to choose decor, we realized the color on the walls was pukey and we had to get the painters back to change from blue to brown. I'm so glad we did that. It really warms up a basement room with no windows. The lighting is what made color selection so tricky. Also in there, we got a leather recliner from Hancock & Moore. And the really neat looking Wisteria Barn door coffee table. Funny thing is that when it arrived, it really did smell like a...barn door! Fortunately that smell has disapated.

just a few ideas that I'd suggest. a plant in the corner where that little bench is. I posted two diff types, either would work. I gave you a side table w/a lamp on the other end. I like the idea of a pouf in this camel color to warm things up a bit, or do a stool or two placed in front of fireplace. I also like these shelves between the two windows. ( I don't know what furry dog is going to do with these,,,maybe have the toddler stand on his back?? lol. hang them well out of reach and they'll be fine. I'd put a few small plants on them. This will eat up that middle space) You could also take these teak decking tiles and attach a plant/pot onto it, and hang two of these between the transom windows. if you want a bench, do something like this in the wood. all of those neutral gray tones make everything seem very cool. add some wood and some texture to warm it up a bit. over the back of sofa do a cool piece of art don't hang them too high. (your tv is hung too high btw. ) and a rug for the sofa area A jute one would work too for the dining area, you could also do this jute rug like shown. for the wall, I'd do another piece of sizable art to hang on that one wall. This one has a larger wall, but look at the black and white picture. basically the same size of yours. you want something this big. Or, do a shallow buffet or console w/a mirror over it and some greenery, like shown here.

@Patricia Colwell thanks! Our TV is in the corner in the bottom right of the bottom picture (you can see our daughter there). We’re doing a corner fireplace there as well. So would you suggest leaving the sofa where it is and doing two chairs where the loveseat is now? Like this pic?
