A C-shaped rolling table that slides OVER the sofa's edge — laptop and dinner land where you actually are. One 1x12, a 1x6, casters, done.

Overall cost: $$. Lumber varies by region, species, and season, so we give a band rather than a figure.
Tools: Drill / Driver, Drill Bit Set, Speed Square. Materials: 1x12, 6 ft, Wood screws, 2", or pocket hole screws, 1-1/4", Wood glue
Pre-drill — pocket holes or countersunk pilots, your choice — and join the top and bottom to the back, outside edges flush, glue at both joints. That's the C; it's floppy on purpose right now.
Tools: Drill / Driver, Pencil, Tape Measure. Materials: 1x6, 2 ft, Wood screws, 2", or pocket hole screws, 1-1/4", Wood glue
Measure and mark the brace's position at the top, middle, and bottom (per the diagram), stand the 1x6 vertically against the back, and screw through pre-drilled holes with glue.
This board is the table's spine — the cantilevered top pushes down, the brace pushes back. Full screws, full glue, no shortcuts on the boring part.
Tools: Drill / Driver. Materials: 1x2, 6 ft, Wood screws, 2", or pocket hole screws, 1-1/4", Wood glue
Attach the 1x2 side footers to the bottom, then the end footers to the bottom and side footers. The back footer end can't take a direct screw — the source says don't worry, and don't: this trim carries nothing. Glue and whatever fastener reaches.
Tools: Drill / Driver, Level, Random Orbit Sander. Materials: Casters, 1-1/2" wheel, Primer, paint, wood filler, sandpaper
Screw the four 1-1/2" casters to the bottom corners, then confirm the whole bottom assembly still clears your sofa's under-height — that clearance is the entire product.
Fill every countersink, sand to 120, prime and paint. Roll it over the sofa foot, open the laptop, and accept that dinner now happens here too.
