More Than Picking Pieces From a Catalog
The right commercial office furniture starts with how your team works, what your brand says, and how the pieces will hold up after years of daily use.
Source COI has supplied and specified commercial office furniture across Southern California and nationwide since 1988, and that experience shapes every project we take on.
Furnishing a new space, refreshing an existing one, or relocating your team? We are your single source for furniture procurement, space planning, and professional installation, serving San Diego, Los Angeles, Irvine, and Orange County, plus organizations across the country.
Furniture for every zone of the workplace, from the lobby to the executive suite.
A Furniture Partner, Not a Warehouse
Anyone can sell furniture. We start by understanding your business and finish when your team is working comfortably in a space that performs.
- A dedicated team of designers and project managers on every engagement
- Independent recommendations curated from many manufacturers, not one stock list
- Three decades as one of Southern California's most trusted suppliers
Our Commercial Office Furniture Collection
Furniture for every area of your workplace, from the lobby to the executive suite, the open floor to the private office. Tap any category to see what we supply.
Benching systems for open plans, private office desk configurations with integrated storage, executive desks for leadership spaces, and height-adjustable standing desks. Every desk is selected for surface quality, structural durability, and fit with your office environment.
Task chairs and ergonomic chairs built for all-day work, plus conference chairs, guest chairs, and lounge seating for common areas. Our ergonomic assessment service helps you configure seating that reduces discomfort and supports long-term wellbeing.
Office conference tables in a range of sizes, shapes, and finishes, from four-person tables to boardroom surfaces. We pair each one with matching conference chairs, credenzas, and presentation furniture for a cohesive meeting room.
Reception desks that balance visual impact with the workspace your front-of-house team needs, paired with lobby seating and soft seating that reinforce your brand from the moment a visitor walks in.
Informal seating for break rooms, collaboration areas, and open corridors. Comfortable, modern pieces that give employees flexible places to work, recharge, and connect outside of formal meeting spaces.
Folding, nesting, and modular training table systems that reconfigure quickly for team meetings, workshops, all-hands sessions, or classroom training, then store just as easily.
Complete private office solutions, including executive desks, credenzas, guest chairs, and guestside seating, for leadership, legal and financial professionals, and anyone who needs a defined, well-appointed office.
Phone booths and acoustic enclosures that give employees a quiet space for focused work, confidential calls, and video meetings, without permanent construction. Ideal for open floor plans that need a balance of collaboration and concentration.
Filing systems and mobile pedestals at the desk, plus credenzas, wall-mounted storage, and open shelving for shared areas. Selected for functionality, finish quality, and fit with the surrounding space.
Monitor arms, keyboard trays, cable management, and desk screens that finish each workstation and keep the office environment organized, ergonomic, and visually clean.
Custom laminates, paint finishes, fabrics, veneers, and bespoke configurations that align precisely with your brand identity and interior design direction.
Premium Manufacturers, Carefully Curated
We work across a wide manufacturer network rather than a single product line, so every recommendation is made because it fits your space, not because it is what we stock.
Herman Miller and Knoll bring ergonomic innovation and modern design, home to icons like the Aeron task chair. SitOnIt adds Hexy and Wit task chairs, Baja stacking chairs, and Gobi lounge seating, while HON covers Ignition 2.0 task seating, the Cofi executive chair, Abound workstations, the Voi private office line, Empower benching, and Preside conference tables.
9to5 Seating supplies the Lilly guest chair and Bella stacking chair. Framery Smart Pods handle acoustic privacy, DeskMakers covers Overture reception units, meeting tables, and Parsons tables, and Clear Design adds Blade benching and Three60 conference systems. Together the roster covers every zone of the workplace across aesthetics, lead times, and budget.
From Planning to Installation
Source COI is more than a supplier. We handle every phase of your project, from the first floor plan through the final piece placed.
3D Office Space Planning
We model your space in 3D before anything is ordered, so you can see desk configurations, conference table placements, and lounge zones in your actual floor plan.

Ergonomic Assessment

The same standards apply either way: durability, ergonomics, modern design, and long-term comfort.
Southern California and Nationwide
We maintain showrooms in Irvine and Los Angeles where clients can experience the furniture in person, then we handle everything from there.

Sitting in a chair or running your hand across a table surface tells you something a catalog photo cannot. Our design team is on hand to talk through your project while you are there.
