Perhaps the answer is a larger table instead. The current one looks to be suited for 2 people. Here's a helpful article you should read. Scroll to the bottom for a link to help with sizing the table for your room as well.

Banquettes are very hard to get into and get out of. The length of your windows makes a back on one very hard.

You need to look at rectangular tables with leaves and/or drop leafs to accommodate small and large gatherings.

Is this a viable possibility?

How many place settings can you get on that table? See the link I sent earlier.

Look at the window in the back of your first photo, and note how much lower it goes than your chairs. You'd probably have to raise the windows on both the left and the back to have a seat high enough, which would be very expensive.

Get a lager round table and position the chairs on the diagonal, so that when the chairs are pulled back, they go towards the corners.

Thank you Deco for nice article, very useful.

@My3dogs about how low windows are at back wall :-))). It is called perspective. For not to be confused look at left wall window. The windows are on the same level.And they are higher chairs level.

Currently I have a 3 ft round table and I can get 4 place settings in there but it is tight. I would love to have a 4 ft round or square table just concerned about the door to the screened in porch hitting the chairs as it opens.

Your chairs would tuck under a larger table, so it might just have the same basic "footprint" as the small one.

I too think a larger round table with a less intrusive base would help a great deal. You have room for it.

I have a 4 ft round plastic table I am going to put in here to see what it looks like. I also ave a rectangular table that I will position (like Judy G suggested) and take a look at what it will look like w a bench under the window.

As mick50 said, the chairs would tuck under the larger table. If you rotate the chairs 45 degrees, there would be more room for the door swing. Looks like you could add a larger glass top to the base there if you like it.

It is amazing when you can put something in a room that you already have...and it works pretty well. Could still do the bench and the back and also have a chair too but kinda digging the way it looks.

Wow, that's a great improvement! I, too, thought to suggest rotating the chairs with the round table, but you may have your solution.

oh that looks great. Normally I'm all about greenery, but I think I'd take that plant out of the corner. Other than that, looks like a winner to me :-)

That table looks wonderful there. Not a fan of benches though.

About that light fixture!!!

You’re better off with a banquet more seating and more room but add seat cushions if you do

Center the table and chairs under the electrical ceiling fixture, add a chandelier and wall decor.

Maybe just getting one banquette sofa bench, and a longer table? Or try a larger round one?
