I'm building this for some friends. The customer does not want a typical lower-mounted stretcher as is found on every Pinterest post. I'm taking a cue from the Shakers and putting a wide stretcher up top under the table. My desk uses this type of construction and I've not had issues with racking.
They want to seat 8 (3 on each side between the legs and 2 on the ends). Any thoughts on the spacing of the legs?
