# Inflatable Support Chairs Sonnet Chair Fuse an Inflatable Fabric Form with a Stainless Steel Frame By Amy Duong | Published 2026-08-21 | Art & Design Source: Trend Hunter, https://www.trendhunter.com/trends/sonnet-chair References: [yankodesign](https://www.yankodesign.com/2026/08/20/heres-what-you-get-when-you-combine-a-beanbag-with-an-inflatable-chair/)  The Sonnet Chair combines the softness of a beanbag with the structure of an inflatable chair. Designed by Carlo Livaja, it uses an [inflatable fabric ball](https://www.trendhunter.com/trends/conqueror-inflatable) shaped and restrained by a bent stainless steel pipe. The base forms a defined, tongue-shaped seating element, while the inflated back provides support for leaning. Rather than allowing the fabric to collapse freely like a traditional beanbag, the frame determines its final form as air fills the cover. The result is a chair that uses inflation as part of its structural system rather than simply as a way to create cushioning. The design takes shape through its inflation process. The fabric begins as a loose form before expanding until it meets the [stainless steel frame](https://www.trendhunter.com/trends/settecento-chair), which limits further movement and establishes the chair’s silhouette. This combination of a rigid structural element and flexible fabric allows the seating surface and backrest to retain their intended positions while remaining visually soft. The approach follows a broader exploration of [inflatable furniture](https://www.trendhunter.com/trends/bote-aero-couch) in which rigid components control expansion.
