The Rather Marvellous Outdoor Mat That Actually Stays Put
Right, so here's the thing. We've all been there at the beach or a festival, wrestling with a picnic blanket that seems determined to become airborne the moment you look away. These fold-up Party Mats in our splendid Mix design are rather different. They're proper grown-up picnic companions that handle sand, grass, and concrete with the sort of quiet confidence we could all learn from.
Why Choose Our Party Mat
Fade-Proof Durability: Made from 100 percent recycled plastic with UV protection built in, these mats won't fade after a summer of use. They'll still look rather good when everyone else's blankets have turned a depressing shade of beige.
Genuinely Handmade: Each one is crafted by hand, which means slight variations in pattern and colour actually make yours feel properly unique rather than mass-produced and soulless.
Utterly Fetching Design: Available in calming earth tones or vibrant rainbow gradations. Either way, your outdoor space gets an instant dose of personality without trying too hard.
One-Year Colour Guarantee: We're so confident in these mats that we're willing to back them with a promise. That's rather reassuring, isn't it.
Wonderfully Portable: Fold it up and it's the size of a blanket. Take it literally anywhere life takes you.

Given how brilliantly these perform and how thoroughly handmade they are, they do tend to find their way into people's baskets rather quickly. If you've been contemplating upgrading your outdoor life, well, this is rather the moment.
SHIPPING + RETURNS
THE RATHER IMPORTANT BITS
This rather lovely piece ships directly from our brand partner - we work with independent brands who are absolutely brilliant and work frightfully hard to create beautiful things.
SHIPPING DESTINATIONS
Now, here's the thing - our wonderful brand partners ship to lots of different places, but not all of them can ship worldwide.
Some are brilliant at international shipping, others prefer to keep things closer to home.
At checkout, you'll see exactly where this particular brand can send your goodies.
We're terribly sorry, but shipping costs do vary rather wildly depending on where you are in the world. The exact figures pop up at checkout - no nasty surprises!
RETURNS
You have 14 days to return items.
Now, we absolutely adore our brand partners - they work incredibly hard and we do try to support them as much as we possibly can. So I'm rather afraid we have to pass the return postage costs back to you. Frightfully sorry about that!
🌍 PLEASE CHOOSE THOUGHTFULLY:
Our wonderful partners put their hearts into everything they make.
Ordering multiple sizes to try at home is rather hard on our planet and makes things jolly difficult for these brilliant independent creators.
When in doubt, do ask us first!
PAYMENT
We're frightfully modern and accept all the usual suspects:
Visa, Mastercard, American Express, PayPal, Apple Pay, Google Pay, and Shop Pay

We Have Lots More Like This.........
Hello, we are Sostter....
Sostter began, as all good ideas do, with a lively conversation and a shared sense of frustration. Why had the world of independent design become so serious, so samey, so… beige? Where was the spark, the imagination, the sheer joy of discovering something that made you stop and stare?
We dreamt of a marketplace that celebrated difference — where curious minds could explore a world of independent brands, design-led makers, and thoughtful artisans. A space that felt exciting, human, and beautifully imperfect.
Today, Sostter brings together remarkable people and their creations — from London to Lausanne, Brooklyn to Berlin — uniting makers and discoverers through craftsmanship, creativity, and conscience. Every object tells a story, and every purchase supports an independent brand doing things differently.
This is just the beginning. But enough about us — step inside, explore our world, and see what catches your imagination.
Giving Back
We’re proud to support Sutton Night Watch, a grassroots UK charity making a real difference in the lives of those facing homelessness. Through regular donations of stock, supplies, and essentials, we back their mission to offer warmth, dignity, and practical help to anyone in need — right where it matters most.
