About this product

The ICB20221 is a seven-piece, flat-packed armchair designed for temporary event seating, exhibition lounges, and promotional displays. It assembles entirely through friction-fit interlocking slots, creating a stable, cross-braced grid without the need for tape, adhesive, or hardware.

Because it relies on deep intersecting slots to form the armrests, seat, and backrest, the design is highly sensitive to material thickness. It requires heavy-duty rigid board, typically 16 mm honeycomb or inverted corrugated board (ICB), and precise CNC routing to ensure the joints lock securely and safely support human weight.

Common uses

Trade show booth seating
Pop-up retail lounges

Practical Uses for Display Furniture

Trade Show and Event Seating

Well-suited for temporary exhibition booths and event lounges where furniture must be transported flat and set up quickly. The large, flat panels offer excellent billboard space for branding, while the tool-free assembly allows event staff to build the seating on-site.

Pop-Up Retail Lounges

Works well as a branded prop or temporary seating in retail installations. The rigid board construction provides a substantial, furniture-like presence that can be fully customized with printed graphics.

Branded Photo Opportunities

The wide backrest and solid armrests provide large, uninterrupted surfaces for logos and campaign artwork, making the chair a useful prop for social media backdrops and interactive event spaces.

Temporary VIP or Waiting Areas

When a hospitality zone needs to be established quickly, these flat-pack chairs can be deployed to create a structured seating area that matches the event's visual theme.

Environments and Applications

Event Marketing and Promotions

Marketing teams use this structure to create immersive, branded environments without the logistics costs of shipping traditional furniture. The knock-down design ensures high pallet density during transit.

Exhibition Booth Design

Designers looking for structural elements that pack flat can incorporate these chairs into custom booth layouts, ensuring the seating matches the surrounding printed displays.

Experiential Retail

Retailers setting up temporary activations can use rigid board furniture to build out a complete environment that is easy to strike and recycle after the campaign ends.

When to Consider Alternative Structures

Permanent Commercial Use

This is a temporary display structure made from paper-based board. It is not suitable for permanent commercial furniture or environments with high moisture exposure, where traditional materials are required.

Multi-Person Seating

If the lounge area requires seating for more than one person, a wider sofa variant may be a better fit than individual armchairs, though it will require different load-span considerations.

Material, Routing, and Finishing Choices

Board Selection and Caliper Matching

The template defaults to a 16 mm thickness. Whether using honeycomb board or heavy-duty ICB, the slot widths in the CAD file must be updated to match the exact measured caliper of the physical board. Mismatched slots will cause the chair to rack, splay, or fail to assemble.

Cutting Method

Standard steel-rule die-cutting cannot process 16 mm rigid board cleanly. This structure requires large-format CNC routers or digital flatbed cutters equipped with oscillating knives or routing bits.

Edge Finishing

Cutting rigid board exposes the internal flutes or honeycomb core along the edges. Decide whether the raw edge fits the aesthetic or if post-cut edge-banding is required, which adds manual labor.

Surface Printing and Lamination

Determine if the board will be printed directly or if a laminated wrap will be applied. Lamination can add a slight amount of thickness, which must be accounted for when calculating the final slot widths.

Adjusting Dimensions and Proportions

Seat Width and Depth

The seating area can be widened or deepened, but increasing the span between the armrests reduces the weight capacity of the seat panel. Wider designs may require thicker board or additional center cross-supports.

Backrest Recline Angle

The recline angle of the backrest can be adjusted for ergonomics. However, excessive recline shifts the center of gravity backward, increasing the risk of the chair tipping or the rear slots tearing out under load.

Armrest Height and Profile

The height and top shape of the armrests can be modified to match a specific design aesthetic, as long as the changes do not interfere with the structural slots that hold the cross-supports.

Packing details

Physical Load Testing

Because this structure bears human weight, physical load testing is mandatory. The actual weight capacity depends entirely on the specific board grade, flute direction, and environmental humidity. Always prototype and test the exact material before a full production run.

Additional notes

CNC Routing Requirements

Due to the thickness of the required board, this structure is typically produced on digital flatbed cutters or CNC routers rather than traditional die-cutting presses.

Center of Gravity

Adjusting the backrest angle or the depth of the seat changes how weight is distributed. Prototypes should be checked to ensure the chair does not tip backward when someone leans against it.

FAQs

Does this chair require glue or hardware to assemble?

No. The armchair is a seven-piece design that assembles entirely through friction-fit interlocking slots. The armrests and cross-supports form a base grid, and the seat and backrest drop into place.

Can this be made from standard corrugated board?

Standard corrugated board will likely crush under human weight. This structure requires heavy-duty rigid board, such as 16 mm honeycomb or Inverted Corrugated Board (ICB), to provide the necessary strength and rigidity.

Why is the exact board thickness so important?

The entire chair relies on slots cut into the panels. If the board is thicker than the slots, the pieces will not fit together. If the board is thinner, the joints will be loose, and the chair will be unstable.

How is the chair shipped?

The seven components are delivered completely flat, which provides excellent pallet density and reduces shipping costs compared to pre-assembled furniture.

What is the weight limit of the chair?

The weight limit cannot be guaranteed by the template alone. It depends entirely on the specific rigid board used, the precision of the cut, and the environment. Physical load testing of a prototype is always required.

Can the shape of the backrest be customized?

Yes, the top profile of the backrest can be modified for branding or custom shapes, provided the changes remain above the structural slots that lock it into the armrests.

Can the chair be printed on all sides?

Yes, the flat panels can be printed on both sides before cutting. This allows for continuous branding across the armrests, seat, and backrest.

How many times can the chair be assembled and disassembled?

Because the joints rely on friction, repeated assembly and disassembly will eventually wear down the edges of the paperboard slots, leading to a looser fit. It is best suited for temporary events rather than daily breakdown.
