In the design world, the conversation this year has universally turned to provenance – the idea that our homes should reflect personal history and character, not just the latest fleeting trends. The era of the predictable, matching furniture set is firmly over. As we collectively lean into a design ethos that prioritizes soul and substance over fast furniture, the trend is now to bring in unique, storied pieces that beautifully clash and complement one another.
And nowhere is this pursuit of personality more effective than in the dining room. This space, whether indoor or al fresco, is the definitive stage for meaningful connection, and the most powerful way to prompt conversation is through pieces that carry a rich, one-of-a-kind narrative.
As a Celebrity Style Editor, catching glimpses of these heirloom pieces in the homes of A-listers is consistently one of the most interesting parts of my job. They know that to successfully break away from a predictable, 'cookie-cutter' aesthetic, they need elements of authentic, storied design.
For a masterclass in how to mismatch furniture, we need look no further than Diane Keaton’s outdoor dining space. Curated by Hollywood's celebrated designer Stephen Shadley, the room is less a collection of furniture and more a deeply personal, eclectic trove. Keaton’s deliberate choice of different-shaped and colored chairs – many showcasing a beautifully weathered patina and an intentional upcycled aesthetic – creates a space that looks curated, not composed.
5 rules for stylish mismatching dining chairs
Although the whole point in this style is for it to feel effortless, not overly styled, there are still some rules to follow if you want to recreate Diane Keaton's laid-back look.
1. Establish a visual anchor (The 80/20 Rule):
To avoid the look of visual chaos that could come with mismatching your furniture, ensure at least one element remains the quiet constant. This is often the dining table itself, but it can also be a dedicated, matching pair of head chairs. This simple repetition provides a foundation of cohesion and keeps the eye grounded as it travels across the eclectic grouping.
2. Harmonize by materiality and patina:
While you shouldn't hunt for an identical wood species, ensure the feel of the materials is aligned. Pair dark walnut with aged mahogany, or light wicker with pale oak. The key is a shared patina – that beautiful, aged quality – that allows the chairs to look like they’ve been collected over many years, rather than haphazardly thrown together in one go.
3. Maintain a consistent scale and sightline
The most practical rule of all is to ensure functionality. While shapes can vary drastically, the overall seat height and depth must be relatively uniform. Chairs that are too tall or too low will disrupt the visual rhythm of the table and, crucially, make dining feel awkward. Respect the vertical line of the table to maintain a sophisticated silhouette.
4. Create intentional repetitive groupings
Resist the temptation to find six completely unique chairs. A more sophisticated approach is to find two or three distinct antique styles and repeat them in pairs around the table. For instance, flank the ends with your two grandest armchairs, then alternate two sets of side chairs. This intentional repetition provides an essential feeling of flow and balance.
5. Leverage upholstery as your unifying force
If your chairs are widely disparate in style – perhaps a rustic Windsor mixed with a refined Louis XV piece – use fabric as your secret weapon to unite them. By choosing one unifying textile (a particular texture, color, or subtle stripe) for all seat cushions or backs, you instantly create a cohesive dialogue between the pieces. It’s the ultimate, bespoke tool for a seamless, expertly curated look.
Shop antique and vintage-style dining chairs
One (or we should say two) of a kind, this pair that are just like Diane Keaton's, are hiding out on Etsy.
Not vintage but looks it, this dining chair would be perfect for creating a mismatched setup. Use the yellow velvet to run through the rest of your selection to create that cohesiveness we've talked about.
This might be a set of matching dining chairs, but there's no denying the character. And if you have a table that sits six or eight, you could use these four as the thread that ties the look together.
Ultimately, what Diane Keaton’s masterfully curated outdoor dining space confirms is that focusing on pieces with genuine provenance is a design principle that transcends fleeting fashion.
The intentional mix of different styles and materials is intrinsically timeless. Yet, this unique, personality-driven approach feels incredibly vital and on-trend for 2025 and beyond. By celebrating the beautiful imperfection of the well-collected and the well-loved, Keaton has given us the definitive blueprint for sophisticated entertaining that will never feel dated.
