What CSI Fullmer does
CBI (Corporate Business Interiors, Inc.), operating via the CSI Fullmer web domain, is a family-owned commercial office furniture and interior solutions dealership founded in 1980 by Hice Stiles and headquartered in Newport Beach, California. The company sells and installs office furniture, pre-fabricated architectural walls, and complementary interior products for enterprise customers across corporate, education, healthcare, government, and multifamily segments. CBI operates as an aligned dealer of Allsteel (a subsidiary of HNI Corporation, NYSE: HNI) and distributes over 100 manufacturer brands including Gunlocke, HBF, HON, National Office Furniture, Humanscale, Normann Copenhagen, and DIRTT. Major named projects include Pacific Life Insurance (1,900 employees across 12 floors), Walt Disney Concert Hall (293,000 SF), City of Hope Hope Plaza (350,000 SF), and the U.S. Naval Air Weapons Station Technology Center ($6.48M FF&E on a $63M BRAC project).
The business operates on a project-based, consultative sales model in which dedicated account managers serve as single points of contact from project inception through installation. Pricing is quote-based with no public price list, and engagements are structured as multi-year contracts around defined project scope. The firm bundles specification, design, project management, delivery, installation, warranty, and asset-management services using DIRTT ICE 3D visualization software and CET/AutoCAD for space planning. CBI maintains a 14,000 SF showroom in Newport Beach and 45,000 SF of warehouse facilities for inventory and asset management.
In May 2023, CBI acquired CSI Fullmer, a long-standing Pasadena-based Allsteel dealer, to expand into the Los Angeles market and consolidate its Southern California footprint. Leadership is provided by Darren Stiles as President & CEO, alongside founders and principals with 20-40+ years of industry tenure. The firm has received consistent industry recognition including IIDA Calibre Awards (2025), NAIOP Project of the Year awards (2023, 2024, 2025), a CoreNet REmmy Award (2018), and an ASID Design Excellence Award (2017).

CSI Fullmer competitors and assessment
Company assessmentOthers
- Allsteel: HNI Corporation subsidiary and CBI's primary manufacturer partner. Allsteel products are specified across CBI's corporate, healthcare, education, and government projects, making Allsteel a critical supplier in CBI's value chain rather than a direct competitor.
- HNI Corporation: Parent company of Allsteel, Gunlocke, HBF, and HON — the core furniture brands CBI specifies. HNI's distribution strategy (and any shifts toward direct enterprise sales) directly shapes CBI's economics and product access.
Broad incumbents
- Haworth: Major office furniture manufacturer competing with HNI/Allsteel and Knoll in the same enterprise verticals CBI serves. Its dealer network includes direct comparables to CBI in the Southern California commercial interiors market.
- MillerKnoll: Holding company formed by the merger of Herman Miller and Knoll, offering a comprehensive portfolio of office furniture brands that compete head-to-head with CBI's Allsteel/HNI lineup for the same enterprise, government, and healthcare customers.
- IA Interior Architects: Global commercial interior design and space planning firm that frequently collaborates with — and competes for — the same enterprise workspace transformation projects that CBI's design and furniture teams pursue.
- Teknion: Office furniture manufacturer with a strong North American dealer network. Competes with CBI for corporate, healthcare, and government furniture specifications in the same enterprise bid processes.
- Steelcase: Largest office furniture manufacturer globally and a direct competitor to HNI/Allsteel (CBI's core brand partner) for enterprise contracts. Operates a dealer network that competes with CBI for the same corporate, healthcare, and education accounts in Southern California.
- Gensler: Largest architecture and interior design firm globally with deep Southern California presence. Frequently engages as the A&D partner on the same corporate, healthcare, and government workplace projects where CBI serves as the furniture dealer and DIRTT installer.
Direct peers
- DIRTT Environmental Solutions: Manufacturer of the pre-fabricated architectural walls and ICE design software that CBI specifies and installs. Both companies serve enterprise, healthcare, and education end customers with similar modular interior build solutions, with CBI operating as a key DIRTT-aligned dealer.
- Empire Office: Large privately-held commercial office furniture dealership serving enterprise, financial, and legal clients with furniture, architectural products, and design services — directly comparable to CBI's business model, customer mix, and project-based revenue approach.
