A Marvellously Versatile Play Sofa
Not your average piece of furniture, this delightful creation is what happens when a child’s imagination meets a bit of design brilliance. Is it a spaceship? A castle? A dignified mattress for naps taken terribly seriously? Yes, to all of the above. Designed with play in mind and chaos in expectation, it’s gloriously modular, beautifully soft, and blissfully lacking in sharp edges.
Why Choose Our Dark Brown Activity Play Mattress Set?
Imaginative Adventures: Transforms into anything from a rocket ship to a reading nook to a delightful sleepover solution. Perfect for curious minds and little dreamers alike.
Cushioned for Courage: Soft edges and flexible form mean your young explorer can leap, tumble, and roll safely, while you sip tea without fretting. Much.
Delightfully Modular: Includes a base mattress, a clever foldy one, and two trapezoidal pillows that sound mathematical but are really good for building forts. All with zip-off covers to survive the occasional juice-box misadventure.
Product Details:
Materials: 100 percent polyester covers and plush polyurethane foam, both certified to OEKO-TEX STANDARD 100, which sounds terribly serious because it is.
Care: Removable covers make it rather easy to clean. Almost like a win in the parenting Olympics.
What's Included: One base mattress, one bendy mattress, and two rather helpful pillows.
Shipping: Varies by location: 24.99€ for select EU countries including Estonia and Germany; 29.99€ for others such as Spain and the UK; and 49.99€ should you reside in the further reaches like Finland or Greece.
Order yours today and let their imagination leap, lounge, and laze in fabulously soft splendour.

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!
The brands we work with all have a chat option, and they love to chat!
PAYMENT
We're frightfully modern and accept all the usual suspects:
Visa, Mastercard, American Express, PayPal, Apple Pay, Google Pay, and Shop Pay
SECURE AS HOUSES
Everything's properly encrypted and secure - your details are safer than the Crown Jewels!
All prices in lovely British pounds £ GBP, though international chaps will see converted prices.
Any payment pickle? We're here to help sort things out! Contact us
We are Sostter
We met as children. Grew up a few streets apart. Built dens, rode bikes, and eventually — built Sostter.
It started with a shared love of objects that meant something…things with a past, or at least a purpose.
Now, Sostter is our grown-up version of a treasure hunt: a space where design meets storytelling.
We curate independent brands, one-of-a-kind finds, and everyday essentials with character.
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.
