I've always preferred side table height to be slightly lower than the arm of the chair or sofa it is next to. That way, the sitter doesn't have to lift their arm to set something down. It's just easier and more comfortable, I think.

Because a Chesterfield has a high side I would think a taller table would work better. I have a chest beside our Chesterfield type sofa. It is 31 inches high and is still slightly lower than the sofa arm.

I have a leather chocolate brown Chesterfield in our den, and use an Eileen Gray adjustable side table with mine. I also like the one I linked below; it has a similar look to your campaign table you like, and it's only 15 inches.

Here is a link that might be useful: Robert Abbey adjustable table

I have chair side end tables....they are more narrow than a regular end table....about 15 inches wide and the height is the same as a regular end table. Enough room for a lamp, coaster/cup and book. Look for chair side end tables and there are lots of narrow tables.

thanks all -- and I love that Robert Abbey table!
