Modular Truss Furniture Series

TPGF’s YY Series By SeongJin Hwang Is A Structural Furniture Debut

SeongJin Hwang’s studio TPGF introduced the YY Series, a two-piece furniture collection built around a repeating “Y structure,” featuring truss-like steel frameworks designed to carry load at domestic scale. The debut includes the Y1 side table and Y6 lounge chair, with the former anchored by a concrete block and the latter formed from six repeating Y modules. The series launched in March 2026 and was noted after prior recognition at Architecture Madrid.

The Y1 pairs a single Y element with a concrete base so a delicate truss logic can perform as furniture; the Y6 scales that logic into a dense, bolted assembly that reads like a miniature industrial rig. Details include exposed bolted joints, criss-crossing metal rods and ribbed panel surfaces that translate architectural load-path aesthetics into object form. The pieces emphasize structural clarity rather than decorative mimicry.

For consumers, the YY Series offers a robust, engineering-forward aesthetic that reframes furniture as small-scale architecture, appealing to buyers who favor honest materials and industrial craft. The collection underscores a broader trend of bringing visible structural systems into interiors, turning engineering language into a tactile, everyday experience.

Modular Structural Aesthetics
A focus on repeatable structural modules creates potential for products that scale from single objects to assembled architectural elements, redefining modularity in consumer design.
Visible Engineering in Interiors
Exposed joints and load-path clarity introduce an aesthetic that normalizes structural honesty, creating room for design-led engineering features to become selling points.
Scalable Truss Furniture Systems
Truss-like frameworks adapted for domestic scale open possibilities for bolted, reconfigurable furniture families that bridge furniture manufacturing and light structural fabrication.

Sectors Adopting This

Residential Furniture
Durable, engineering-forward pieces present an opportunity for home furnishings that prioritize structural performance and long-term adaptability over purely decorative trends.
Commercial Interiors
Public and hospitality spaces could integrate visible structural fixtures as brand-defining elements that communicate robustness and industrial craft.
Prefabricated Construction Components
Small-scale truss modules suggest potential for offsite-manufactured, load-bearing components that blur the line between furniture suppliers and building-material manufacturers.
