Soft Spaces for Big Adventures
Part magical play kingdom, part cosy reading den, this delightfully stylish Activity Play Mattress Set in Pink is the sort of thing that whispers, quite persuasively, to your inner child (and your actual one too). Whether today's flavour is pirates, astronauts, or professional lounging, this play set rather heroically adapts, folds, and supports every leap of imagination and actual leap alike. And tidies up better than I do, frankly.
Why Choose Our Activity Play Mattress Set?
Fantastical Flexibility: Sofa? Fort? Squishy spaceship to Pluto? Converts in a blink, and folds away like it was never there. Almost eerie, really.
Encourages Imaginative Play: Say farewell to screens and hello to castles built out of daydreams and good old-fashioned sofa pillows.
Gentle on Growing Bodies: Soft foam, no corners of doom, and plenty of bounce for little knees and heads that can’t sit still.
Product Details:
Base Mattress: Plushly thick and folds like a pro. Removable, machine-washable cover. Dimensions: 170 x 85 x 15 cm.
Flexible Mattress: Slightly leaner, splendidly bendy, and just as washable as its plumper sibling. Dimensions: 170 x 85 x 8 cm.
Two Trapezoidal Pillows: Perfect for throne backs, ramp art, or pretending to be part of a cloud. Dimensions: 56 x 56 x 31 cm.
Cover Fabric: 100 percent polyester, OEKO-TEX STANDARD 100 certified, splendidly soft and very forgiving to jam stains.
Foam: Made of flexible polyurethane foam, marvellously comfy and approved for all their flops, hops, and full-body storytelling.
Care and Storage: Both mattresses unfold for play and refold into tidy layers, like a very well-behaved piece of cake.
Your Adventure Awaits
Add this fabulously made play set to your home before your next rainy-day rescue mission. Time waits for no rocket ship...
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!
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.
