Marvellously Squishy Adventures Await
Imagine a world where your toddler builds castles before breakfast, scales pastel mountains before lunch, and heroically rescues stuffed animals from imminent doom by tea time. This soft play foam block set is their gloriously bouncy ticket to all things imaginative, energetic, and (dare we say) ever so slightly civilised. Made for climbing, crawling, lounging, tumbling and the occasional dramatic swoon, it’s indoor play that feels like an epic quest — minus the muddy wellies.
Why Choose Our Soft Play Foam Block Set?
Encourages movement: Builds strength, balance and, quite possibly, Olympic-level couch jumping skills.
Inspires creativity: Spaceships, forts, elaborate biscuit factories. Whatever today’s theme, the blocks are ready.
Softens chaos nicely: Redirects all that marvelous energy away from your antique vase and into something far less breakable.
A sensory treat: Gently textured and pleasingly pastel, ideal for tiny hands and curious taps.
Screen-free diversion: Proper, real-world play where giggles are live and unbuffered.
Fosters togetherness: Teaches the noble art of cooperation as siblings negotiate for block-building rights.
The plump, plush blocks are just the right size for toddler acrobatics, spontaneous lounging, or impromptu pet lounging (which seems to be a thing now). However your little one plays, it’s fabulously flexible and grows with their imagination. You may even press one into occasional service as a footrest during parental negotiations.
Product Details:
Durability: High-density foam that keeps its composure, even after dramatic reenactments of pirate battles.
Easy to clean: One wipe, and the remnants of snack time disappear as if by magic.
Handmade: Lovingly put together by actual people who think corners should be stitched properly.
Safety certified: Meets child safety standards in the EU, USA, Canada and the UK. No surprises here.
Made in the EU: Crafted with care and a proper eye for quality somewhere charmingly Northern European.
Each piece is wrapped in soft, wipeable eco-leather that feels rather nice and looks even better. Delightfully durable and endlessly entertaining, it’s the sort of toy they'll return to again and again. Quite right too.

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!

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.
