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.

Consider a set of bunching tables for your coffee table. This will allow you to put a small gap between them if you need to fill the space for an appropriately scaled length: A set of nesting tables might also be an option: Happy shopping!

@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?
