A grown-up version of the toddler TV tray table, that can be used by one Sim to eat a meal, as any regular dining chair.
A Sims 4 armchair redone as dining chair, so it can be used with the TV table, the matching sofa redone as dining-booth (and with matching colors)
A grown-up version of the chalkboard table and school-like chair. I wanted to turn them into activity table, but still wanted something a bit different, so I made a collective activity table. It’s actually the chair that works as activity table; the table has a small footprint so it doesn’t prevent Sims from drawing (but it also means Sims can walk through it if there’s no chair to block their way)
The Eco-living activity table turned into regular desk and chair, with a dirty and clean options.
