King | Quattrini Interiors (KQI) is a full-service interior design firm based in Denver, Colorado, serving residential and commercial clients. Founded by Kelley King and Morgan Quattrini, the firm combines creativity, organization, and practical project management to create spaces that reflect each client’s vision while supporting everyday life. Its approach brings together timeless style, functional planning, and a low-stress experience.

KQI offers hard interior design services, including guidance on flooring, tile, paint, cabinetry, and fixtures, as well as finish selection, ordering, and coordination with vendors. For soft interiors, the team provides space planning, furniture arrangement, and sourcing for furniture, case pieces, and accessories. The firm also guides home renovations of varying sizes, partnering with homeowners and contractors on layouts, finishes, furnishings, budgets, and project schedules.

Each engagement begins with a conversation about project goals, lifestyle, preferences, and budget. KQI then develops and reviews design concepts, finalizes selections, and oversees installation through project tracking and site check-ins. Its goal is to make each space both distinctive and useful.
