I would do square...using the arm length as a guide.

Hi, Marlene, can you show the room and sofas? It will depend on various factors, such as size of your sofa arms, is it open concept or against walls, how close are they, etc.

I searched ’end table between two sofas’ and lots of images came up.

I have a sofa and love seat in an L shape and use an old family butcher block as an end table. (It was only ever used to hold a cake stands, but is pretty cool-looking.)

Here are a variety of solutions for the intersection of the sofa and loveseat or club chair. They don't all have to be square or rectangular.

Ignore the fact of it being two couches and choose shape and height based on couches and size wise, if a lamp will be used.

Hard to find a 36"square table. Any ideas? My furniture (2 leahter grey couches) will be delivered in a week. I am just shopping around to see what's available in an end table. I have my coffee table which I love. Top is whwite marble and bottom is a light mango wood so I really want a wood end table to tie it tofether

What shape is your coffee table? If it's angular, I'd do a round end table. I think the rule is that you want your table to be within 1-2" of your sofa arm height so it's comfortable to reach over and set down a glass etc. There are good pictures posted above, and most of them have round tables and look so pretty.

I have a large round coffee table that I love so I want a square end table
