The sky is the limit when it comes to aesthetics in a sofa pocket organizer. You can match the color and fabric with the upholstery or pick a contrasting one. Materials like leather are universal and blend in with any type of décor theme.
More importantly, ensure that the pockets don’t appear stuffed and bulky. That’s an eyesore at best. We’d personally attribute more importance to the functionality and the build quality than the aesthetics. But we know that some protean furniture pieces leave a lot to be desired on the aesthetic front.
