    Mechanical & Industrial Details

    The Otis Steel base features exposed mechanical gearing, reinforced cast iron supports, and embossed "OTIS STEEL" branding on each base end. The addition of a third leg and dual stretchers enhances structural integrity for larger formats, ensuring stability across the full span.

    High-quality steel gears allow smooth height adjustment through a full 10-inch range, while iron-wheel casters echo early factory transport systems — blending function with historical design.

    Inspired by the muscular gantry pivots and furnace-ladle arms of the historic Otis metalworks facility, the base celebrates visible engineering rather than hiding it — making the mechanics part of the design.


    Work + Gathering Versatility

    At 120” × 40”, this configuration is ideal for conference rooms, collaborative workspaces, hospitality settings, and large communal environments.

    Conference Use:
    Adjust from standard seated height (30”) to standing collaboration height for improved ergonomics and engagement.

    Communal / Dining Use:
    Transitions seamlessly from dining height to counter or bar height (up to 40”), making it equally suited for shared dining and entertaining spaces.


    Industrial Heritage

    Established during the U.S. Industrial Revolution, Otis Steel was a cornerstone of Cleveland’s manufacturing history from 1875 to 1942. This table draws inspiration from the powerful industrial forms of that era, combining historical influence with modern-day adjustability, scale, and mobility.

    Designed in Knoxville, Tennessee and assembled in-house using a combination of sourced components and hand-finished craftsmanship to ensure lasting strength and authentic industrial character.

Frequently Asked Questions

  • How does the adjustable-height crank mechanism work?

    Knox Deco adjustable-height conference tables use a manual hand-crank mechanism to raise and lower the tabletop—no electricity is required.

    Before adjusting the height, make sure the applicable locking bolts are unlocked. Turning the crank engages the mechanical lift system, allowing you to raise or lower the tabletop to your preferred height.

    Once the table reaches the desired position, the locking bolts can be tightened again where applicable to help secure the table at that height. Always unlock the applicable locking bolts before attempting to crank the table again.

  • What is the height range of the conference table?

    The exact height range varies by base. Knox Deco conference tables provide approximately 10–11 inches of manual height adjustment, allowing the table to transition from a traditional seated conference-table height toward counter or standing meeting height.

    This flexibility makes the table useful for traditional meetings, presentations, collaborative work sessions, and other environments where different working heights may be beneficial.

    Please refer to the individual product specifications for the exact minimum and maximum height of your conference table.

  • Can the conference table be used for standing meetings?

    Depending on the particular model and the height of the users, the upper adjustment range may work well for standing meetings, presentations, or collaborative work sessions.

    Because everyone's ideal standing work height is different, we recommend comparing the table's maximum height with the working height you need before purchasing.

  • Does the tabletop stay level when the height is adjusted?

    Yes. The mechanical crank system is designed to raise and lower the tabletop while keeping the work surface level when operated properly.

    Because these are large, substantial tables, height adjustments should be made carefully and according to the instructions for your particular base.

    Once you reach your desired height, the locking bolts can be tightened where applicable for additional security. Always unlock them before adjusting the height again.

  • What are the conference tabletops made from?

    Knox Deco conference tables are available with different tabletop materials and finishes depending on the particular model.

    Our wood tops are crafted from genuine hardwood and may include smooth solid hardwood or reclaimed mixed hardwood options depending on the table and finish selected.

    Please refer to the individual product page for the specific tabletop materials and finishes available with your conference table.

  • Will my hardwood conference table look exactly like the photos? Are samples available?

    No. Real hardwood naturally varies, which means no two Knox Deco tabletops will be exactly alike.

    Variations in wood grain, color, knots, markings, and other natural characteristics should be expected and are part of the character of genuine hardwood furniture.

    Wood finish samples are available upon request if you would like to see a finish before ordering.

  • What size are Knox Deco conference tables?

    Our conference tables are designed for larger meeting and collaborative spaces. A common Knox Deco conference-table configuration features a 120" Ă— 40" tabletop, providing a substantial 10-foot work surface.

    Because of the table's size, we strongly recommend measuring the conference room as well as all doorways, hallways, elevators, stairways, and turns along the delivery path before ordering.

    Please refer to the individual product specifications for the exact dimensions of the table you are considering.

  • How many people can sit at a 10-foot conference table?

    A 10-foot conference table provides generous seating for meetings and collaborative work. Actual seating capacity depends on the size and style of the chairs, the amount of personal workspace desired, and whether chairs are placed at the ends of the table.

    For a professional conference-room setting, we recommend allowing enough space between chairs for laptops, paperwork, and comfortable movement rather than maximizing the number of seats.

  • Is assembly required and how heavy is the conference table?

    Yes. Due to their size and substantial construction, Knox Deco conference tables require assembly at their final location.

    Our 10-foot conference tables use multiple base supports to provide stability across the extended tabletop. These are exceptionally substantial pieces of furniture and can weigh several hundred pounds depending on the base and tabletop selected.

    We strongly recommend planning the delivery path and final placement before the table arrives.

  • Is white-glove delivery included with my conference table?

    Yes. Complimentary white-glove delivery is included with Knox Deco conference tables for first-floor delivery with no stairs. This service includes bringing the table into your space, assembly, and placement in your desired location.

    If delivery requires stairs, an elevator, or other special access considerations, please contact us before ordering so we can provide a delivery quote based on your location and access requirements.

    Because our conference tables are exceptionally large and heavy, we also recommend confirming doorway, hallway, and entry dimensions before delivery.

  • How should I care for my conference table and crank mechanism?

    For solid hardwood and reclaimed mixed hardwood tabletops, clean the surface with a soft cloth and use a quality furniture polish or wood oil as appropriate. Avoid harsh chemicals, abrasive cleaners, excessive moisture, and allowing liquids to remain on the wood for extended periods.

    The moving crank and gear components should also be lubricated periodically. We recommend applying a small amount of bicycle lubricant approximately once every six months to help prevent the moving components from drying out and to keep the mechanism operating smoothly.

    Always follow the locking and unlocking procedure for your particular base before adjusting the table height.

    Otis

  • What makes the Otis Adjustable-Height Conference Table different from other Knox Deco conference tables?

    The Otis combines substantial cast-iron construction with distinctive iron casters, giving it the authentic character of vintage factory equipment and early industrial machinery. For the 10-foot conference table, the Otis uses a three-leg base configuration to support the extended tabletop while maintaining the collection's recognizable mechanical design.

    The manual hand-crank system allows the tabletop height to be adjusted without electricity, making the Otis equally suited for traditional seated meetings, presentations, and collaborative work sessions at different working heights.

    At 10 feet long, the Otis creates an impressive centerpiece for a conference room, executive office, or collaborative workspace. For customers looking for a conference table with true old-world industrial character, the Otis combines functional height adjustment, substantial cast-iron construction, and distinctive iron casters in a statement piece designed for larger professional spaces.
