# Modular Truss Furniture Series TPGF’s YY Series By SeongJin Hwang Is A Structural Furniture Debut By Kanesa David | Written with AI assistance | Published 2026-04-07 | Art & Design Source: Trend Hunter, https://www.trendhunter.com/trends/yy-series References: [yankodesign](https://www.yankodesign.com/2026/03/29/furniture-that-borrows-its-bones-from-architecture/) & [cfa.hongik.ac.kr](https://cfa.hongik.ac.kr/)  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](https://www.trendhunter.com/trends/permanent-camping-iii). 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.
