Burrow

Burrow's Nomad collection solves sofa-buying pain with a modular design that ships in boxes and assembles without tools in 10 minutes—a process 30% faster than Castlery's traditional assembly. Born from a Wharton Business School project, it became the default recommendation in best-sofa roundups from 2019 onward. The sofa includes built-in USB ports and a hidden ledge shelf, features that proved gimmicky yet effective in marketing. At an average price of $1,500, it's 25% cheaper than the typical modular rival. The real innovation was transforming sofa-buying into a laptop-ordering experience, removing the stress of showroom visits.
