Life-size building sets · For all ages
Build with it.
Play on it.
Build a fort. Build a table. Build whatever you imagine.
Funphix is a DIY playground. Kids lock tubes and connectors into forts, climbers, playhouses and slides. Add wheels and it’s a cart. Then they play on what they built, and tomorrow they build something new.

How it works
From a box of tubes to a life-size structure.
No tools needed beyond the little key in the box.
1
Connect
Slide tubes into a connector. Connectors come in different angles, so the tubes can extend in multiple directions.
2
Lock
Pop in a Funphix locking screw. One quarter-turn with the special key locks it solid, and kids can do it themselves.
3
Use it
Sit in it, slide with it, hide in it, climb on it. Structures hold kids up to 110 lbs, indoors or outdoors.
4
Rebuild
Quarter-turn back to unlock. Tomorrow it’s a bed, table, a pirate ship or a ball pit. Same pieces.

Grows with them
From first climb to their own designs.
The same set keeps up as they grow. Add slides, panels and wheels whenever they're ready. See add-ons →
Little ones
Crawl through it, climb on it and build it together with you. Great for balance and motor skills.
Growing builders
Snap tubes in, lock pieces with the key and help plan the next build.
Big kids
Design their own forts, carts and hideouts, then make them bigger with slides, panels and wheels.
Indoors or out
Playroom or backyard. Same fun, all year.
Build it inside when it’s cold, take it outside when it’s warm. The same pieces work anywhere, any season.
Indoors, all year
Rainy days, snow days, any day. Build a climber in the playroom, a fort in the living room or a cozy nook in their bedroom. Take it apart when you need the room back.
“I built it in my son's room for his birthday. He was ecstatic.” — Funphix parent
Out in the backyard
When the weather warms up, move it outside. Build a climbing bar, add a slide or a full Build ‘n’ Splash pool and turn the yard into a playground.
“It was inside at first for the winter, but we brought it outside for summer. All the neighborhood kids play on it.” — Funphix parent
What Funphix families build
One set. A boat on Monday, a water park by Saturday.

The captain's boat
I helped her build a boat so she could be a captain, setting sail with her crew of stuffed animals.

Backyard water park
We built a bridge and slide into a blow-up pool and made a mini water park in our backyard!

Birthday battle fort
Hide-outs, obstacles, even an ammo hut for the party. It was awesome.

Funphix in the water
Got a pool? Meet Funphix Pool Platforms.
A sturdy platform that sits in the water, so little swimmers can stand, rest and build confidence. Used by swim schools, made for home pools too. From $232.
Why parents choose Funphix
The alternative was the tablet.
Hours, not minutes
Most families in our survey say a build keeps kids busy for 1–2 hours.
Memories, built together
Parents and grandparents build right alongside them. The boat, the fort, the birthday surprise become family stories.
The toy you remember
Plenty of parents and grandparents had a set like this growing up. Now they get to share it.
Engineering, sneakily
Planning, trial and error, and learning what makes a structure sturdy.
Indoors or out
Living room in winter, backyard in summer. Same pieces, all year.

"Is it worth the price?"
“I was hesitant about the price at first, but we have used ours for 4 years and its still going strong, so I feel like we made the right call.”
— Funphix parent
A toy to hand down.Durable pieces built for years of play, so it moves on to younger siblings and cousins, and one day maybe grandkids.

Educational
Learning they can climb inside.
Every build practices STEM, math, sensory and motor skills, and a kindergarten curriculum for Funphix sets is on the way. Families in Florida and Arizona can order with their state education funds.
Schools, daycares & groups
A playground the class builds together.
Group builds teach teamwork and early engineering. Book a Funphix session or ask about classroom pricing.
The gift they'll still play with in October.
Not sure which set to pick? Give a Funphix e-gift card: $25, $50, $100 or any amount you choose. It arrives by email, ready to use.
