Pikler Triangle or Climbing Arch? Why We Chose an Arch That Flips Into a Rocker
If you've started shopping for a climber, you've probably seen two shapes come up again and again: the Pikler triangle and the climbing arch. Both give little ones something to pull up on, climb over and practice balancing on. So which one should you get?
We make a climbing arch, so we're not exactly neutral. But we'll tell you why we chose it, what a triangle does well, and when a triangle might be the better fit for your home.
Where the Pikler triangle came from
The triangle is named after Dr. Emmi Pikler, a Hungarian pediatrician who believed babies should be free to move and climb when they're ready, without a grown-up placing them on things. Her climbing frame was low enough for a baby to pull up on, climb a rung or two, and go higher only once they felt confident.
You'll often see it grouped with Montessori furniture. It isn't strictly Montessori, but the ideas fit together well: give children the freedom to move and figure things out for themselves.
What's the difference between a Pikler triangle and a climbing arch?
A triangle is mostly a climber. Children go up one side and down the other, and many triangles fold flat and work with add-ons like ramps and slides.
An arch, often called a Pikler arch, is a curved climber. Little ones can climb over it, crawl under it, or throw a blanket over it and turn it into a fort. And if it's built to flip, it becomes a rocker too.
Neither one is better for everyone. They're just good at different things.
Why we chose the arch
To be honest, we didn't sit down with a long list of pros and cons. We liked the arch, and we had a feeling families would too. Then Haley, Halle's aunt, who has a degree in early childhood development, helped us see what a well-designed arch could do, and that sealed it.
For our family, the arch does just about everything a triangle does, and the rocker side adds a whole new way to play.
How we designed our climbing arch
Like everything we make, it started as a rough sketch. Together with Haley, we kept refining it until it worked well for little climbers, and until the parts fit neatly on a sheet of Baltic birch plywood with very little left over. How well it works for your child and how little we waste both matter to us.
Our first sketch had a perfect half-circle curve. As we refined it, we made the curve wider and lower, more like a gentle hill than a half circle. The gentler slope makes it easier for little ones to climb up and over, and a little easier coming down the other side. It also makes it more comfortable to rock in.
As we drew up the arch, Haley guided almost every detail, using her early childhood development education and a lot of care. She chose flat planks instead of the round dowels you see on most climbers, because planks give small feet more to stand on and are easier to balance on. She set the spacing between the planks with little hands and feet in mind, and she decided where the handholds go so children can grab on as they climb, pull up or rock. Our job was making it all look as good as it works.
We also kept it on the smaller side on purpose, with crawlers in mind. It's 38 inches long, 19.5 inches wide and 15.75 inches tall, so it takes up some room, but it doesn't take over the living room.
A place to practice standing, balancing and first steps
Before babies walk, they spend a lot of time pulling up on furniture, standing for a second or two, and cruising along the couch while they figure out balance. A climbing arch gives them a sturdy, child-height spot to practice all of that on their own terms.
The handholds are within easy reach for pulling up. The flat planks give little feet a steady place to stand. And the low, gentle curve gives early climbers somewhere to try their first steps up and over. No piece of furniture can make a baby walk sooner, but an arch gives them a place to practice standing, balance and coordination without a grown-up holding them up. That's the kind of free movement Emmi Pikler believed in, and it's a big part of why we designed ours the way we did.
The rocker side works the same way. Flipped over, the sides are low enough for little hands to grab, so babies can hold on, pull up and stand. The gentle rocking under their feet gives them a little extra balance practice, with a grown-up close by.
Why the rocker side matters
Flip the arch over and it becomes a rocker. Haley points out that slow, rhythmic movement like rocking is something many children find calming, and that climbing and rocking both give them practice with balance and with figuring out where their body is in space.
Our Baltic birch is dense, so the arch has some weight to it, and that weight is part of what makes it feel so solid and steady. A grown-up can flip it from arch to rocker easily, and now that Halle is a toddler, she likes to do it herself.
How Halle uses hers
Halle's arch typically stays in the living room, and it's one of the kids' favorite things to play with every day. She got confident on it fast. Now she climbs over it, runs across it, and stands up or sits down to rock. She's thrown a blanket over it to make a fort, turned it on its side to run a pretend coffee shop, and sometimes she even rocks her little brother in it.
When a triangle might be the better fit
An arch doesn't fold, so plan for it to stay out. Ours is on the smaller side, but it does need a spot. If you need something that folds flat between play sessions, want a taller climb for a confident climber, or want to add a ramp or slide, a triangle might suit your family better.
Tips for getting started with a climbing arch
These work with any climber, not just ours.
- Let them go at their own pace. Just like Pikler believed, children climb when they're ready. Skip placing them on top and let them figure it out.
- Set it on a rug or play mat. It gives the arch a cozy spot and a softer landing for the little tumbles that come with learning to climb.
- Stay close, especially at first. A grown-up nearby makes new climbers feel braver.
- Try both sides. Some little ones go straight for climbing, others love rocking first.
- Add a blanket. It turns into a fort or reading nook in seconds.
What other parents say
One grandparent called it very nicely made and a great gift for their grandson. You can read the reviews on the Climbing Arch page.
Halle's verdict: It's a climber, a rocker, a fort or a coffee shop, depending on the day.
