How to make a sofa from these old tables

How to repurpose old tables like the one in the image into a sofa. These tables are very old and good quality teak tables. But are slightly less in dimension needed for a decent sized sofa. Tables are sort of 17W x 36L x 31H (all in inches). I guess for a sofa we need a good 24 inches. I want to keep the cutting work to the minimum (I dont have much experience of woodworking). What would be a better idea to create a sofa (kind of 6 feet) or even a L shaped corner sofa)? I would have around 8 to 10 such tables (almost same dimension though some could be slightly different).
