I hate losing things down the backs of settees.
More than that, I dislike feeling around down there in search of lost items (and usually discovering mummified popcorn, or sultanas, instead).
Today’s invention is a simple fabric channel (green), which forms a continuous membrane, so that lost items must be caught by it, rather than descend beyond sight.
The membrane would be zipped in place (white), allowing the usual seat cover washing.
The geometry of the channel could be made with a slope from back to front of the settee, so that items would have a tendency to shuffle forwards before emerging onto the floor.
