In October 2025, a new aesthetic is shaking up TikTok and establishing itself as the ultimate decor trend of the moment: 'Eclectic Grandpa'. With over 450 million views on the hashtag #EclecticGrandpa, this vintage masculine style is massively appealing to Gen Z who are reinventing their grandfathers' universes into warm and personalized interiors. Patinated leather armchairs, dark wood bookcases, collections of pipes or globes: the codes of bourgeois living rooms from the 80s-90s are back in force, but with a resolutely contemporary touch. Here's what you need to know about this trend that is disrupting vintage decor codes.
A trend born on TikTok that explodes the counters
It all started in July 2025 with some Gen Z content creators sharing their interiors inspired by the paternal universe. The phenomenon gained spectacular momentum in September, propelled by decor influencer @oldsoulsaesthetic and her 2.3 million followers. Unlike cottagecore or grandmillenial styles which are predominantly feminine, Eclectic Grandpa embraces vintage masculinity: dark wood paneling, club armchairs in leather, banker lamps in brass, and collections of unusual objects. Young people aged 20-30 see it as an antidote to cold minimalism and a way to create spaces rich in history and character.
The iconic pieces that define the style
On TikTok, certain elements consistently appear in Eclectic Grandpa interiors. The aged leather club armchair reigns as a centerpiece, often sourced from Leboncoin or Vinted. Solid wood wall bookcases are overflowing with antique books with hardcover bindings. We also find notary desks, retro globes, lamps with green fabric shades, and even collections of vintage masculine objects: pipes, binoculars, crystal whisky decanters. Walls are adorned with mismatched gold frames and botanical engravings. The whole creates an atmosphere of a modern cabinet of curiosities, far from Instagram uniformity.
Why Gen Z is crazy about this vintage style
Several factors explain this massive enthusiasm. First, a quest for authenticity in a digital world: these interiors tell stories and reject mass consumption. Then, the economic accessibility: sourcing from flea markets or recovering family furniture costs less than buying new items. Finally, this style allows for more fluid gender expression, with young women freely appropriating these traditionally masculine codes. On Reddit and Pinterest, discussions revolve around 'how to mix Eclectic Grandpa with other styles': many combine it with japandi or mid-century to soften the overall look.
The impact on the second-hand market
This trend is causing a real boom in masculine vintage furniture on resale platforms. Selency and Leboncoin report an increase of 180% in searches for 'vintage leather armchair' since August 2025. Antique dealers note that dark wood furniture, long shunned in favor of light Scandinavian styles, is now selling out within days. Some Parisian antique shops have even created 'Eclectic Grandpa' sections to ride the wave. However, this rush towards vintage raises questions about price inflation and the authenticity of some pieces 'artificially aged' to meet demand.
And after? Longevity or fleeting trend
Trend experts are questioning the sustainability of this phenomenon. For some, Eclectic Grandpa represents a real cultural shift towards more personalized and sustainable interiors, continuing the anti-fast furniture movement. Others see it as a simple TikTok trend that will fade out by the end of 2025. One thing is certain: this trend has already influenced the autumn-winter collections of mainstream decor brands, with Maisons du Monde and H&M Home launching their 'Masculine Heritage' lines this month. The Eclectic Grandpa style has in any case succeeded in its challenge: making masculine vintage a creative playground for an entire generation.
