why children stay in it

a room they ask to go into.

A playpen is something a child tries to get out of. Arc is the opposite.

Most things made for this job keep a child in one place, and stop working the moment the child would rather be somewhere else. We designed for the child first: somewhere of their own, in a home full of adult sized things. A door they walk through, soft walls to lean on, mesh to see out of. Held, not shut in.

Filmed at home, on an ordinary afternoon.

No primary colours, no cartoon characters. Just Sage and Off-White, calm enough for the living room.

Up to two children at a time, for awake play with an adult in the room.

made for apartments

smaller than it looks.

Designed for HDB flats and condos. Open, Arc takes less floor than a Tumble playmat. Folded, it goes in a cupboard.

Seen from above: Arc would sit on a Tumble playmat with room around the edge.
  • the living roomBeside the sofa, not instead of it, and calm enough to stay out when friends come over.
  • the bedroomA room of their own inside their room. Folded into the cupboard when you want the floor back.
  • the balconyFresh air without going anywhere. Somewhere shaded, set well back from the railing, and in when it rains.

one arc, a hundred afternoons

it can be anything. they decide.

Ask a toddler what it is and the answer changes every day. A few to start with.

No. 01

a fort you don't have to build

No sofa cushions all over the floor, and nothing to take down before dinner. Up in minutes, away in minutes.

No. 02

for tumbles

When the energy has to go somewhere. Rolling, wriggling and some bouncy time on the soft floor, with you close by.

No. 03

a reading nook

Cushions in, books in, and soft light through the mesh. The same story, again, by request.

No. 04

a calm down corner

Somewhere soft to go when the day gets too big, and to come back out from when they're ready.

No. 05

a clubhouse for two

Siblings, cousins, best friends. Two at a time, which makes it extremely exclusive.

No. 06

their room at grandma's

It folds into a duffle bag, so the unfamiliar flat gets a corner they already know.

Will it fit, and where does it go when it's away?
Open, Arc is 140 W × 160 D × 150 H cm, a smaller footprint than a Tumble playmat and sized for HDB flats and condos: the living room, a bedroom or a shaded balcony. The built-in electric pump draws the air out in minutes, and it folds down to 40 × 35 × 20 cm and 6 kg, small enough for a cupboard or a duffle bag.
Does it get hot inside?
The walls and roof are mesh rather than solid fabric, so the air passes straight through instead of sitting inside. That was the point of the design, for the climate it was made in.
What age is it for, and can two go in together?
From 12 months, with no upper age. Up to two children at a time, for awake play with an adult in the room.
Can I leave them in it?
No. Arc is for awake play with an adult in the room. The mesh lets you see in from across the room, but it is not a place to leave a child on their own.
Can they sleep in it?
No. Arc is not a cot, a travel bed or a sleep space, and it has not been made or tested for sleep. If a child gets drowsy inside, move them to a proper sleep surface.
