Owned by a small family MoogCo Baby is a family-owned shop. Every order supports a real family who personally stands behind what we sell — thank you for shopping small. 💚
The RAD Play Cubes are open ended climbing and exploration structures designed to support curiosity, movement, and gross motor development from infancy through early childhood. With their simple form and sturdy construction, Play Cubes invite children to move, climb, crawl, and imagine at their own pace.
For younger children, the Play Cube offers opportunities for crawling through openings, pulling up, cruising, and early climbing. As children grow, it becomes a platform for more confident climbing, imaginative play, and physical challenges. The circular openings create inviting portals that can become hideouts, tunnels, or imaginative micro environments, depending on how a child chooses to play.
Play Cubes can be used on their own or connected to other RAD climbing pieces. Add a ladder or a Reversible Climbing Ramp to create a slide, bridge, or pathway between structures, allowing children to design and redesign their play space while building coordination and confidence.
Handmade in our shop from premium Baltic birch wood, the Play Cube reflects RAD’s commitment to thoughtful design, quality materials, and sturdy construction. With 3.5 inch spacing between rungs and a strong frame that supports up to 250 pounds, it is built for active play and shared use.
While designed to encourage exploration and movement, children should always be supervised during play to ensure safe use.

Each Play Cube is handmade from premium Baltic birch wood, giving it a smooth finish and a sturdy frame. The simple, open design means it fits naturally into a living room or playroom without feeling like a big plastic toy.

Babies use the circular openings to crawl through, pull up, and cruise, while toddlers turn the same cube into a climbing challenge. The design supports gross motor development at every stage, from first movements to confident climbing.

The circular portals can become tunnels, hideouts, or tiny imaginative worlds depending on how your child wants to play that day. Because there is no single right way to use it, the Play Cube keeps kids engaged long after typical toys lose their appeal.
Climbing structures come in different shapes and add ons, so it helps to think through how your child will actually use it before you buy.
- Consider your child's age: Younger babies benefit most from crawling through openings and pulling up, while toddlers get more out of climbing on top. The Play Cube works across this range, but keep your child's current stage in mind when introducing it.
- Think about your space: A single Play Cube has a compact footprint, but if you plan to add a ramp or ladder later, measure the area you want to dedicate to open play so there is room to expand.
- Decide if you'll expand the setup: If you like the idea of building a bigger climbing area over time, look for pieces designed to connect together, like a ladder or ramp that attaches to the cube.
- Check the weight capacity and construction: For a piece meant to be climbed on, sturdy joinery and a clear weight limit matter more than extra features. A simple, well built structure will outlast one with unnecessary add ons.
- Plan for supervised play: Any climbing structure, no matter how well made, should be used with an adult nearby. Choose a piece that fits into a space where you can easily keep an eye on play.
What age is the Play Cube designed for?
It is designed for children from about 9 months up to around 5 years old. Younger babies tend to use it for crawling and pulling up, while older toddlers use it for climbing and imaginative play.
Does the Play Cube arrive assembled?
No, it ships unassembled with instructions included. An electric screwdriver is recommended to make assembly easier.
Can the Play Cube be used outdoors?
It can be used outside for short periods, but it is designed for indoor use. Prolonged exposure to moisture and UV rays is not recommended, since it may affect the wood over time.
How much weight can it hold?
The frame is built to support up to 250 pounds, so it can handle active climbing and shared use by more than one child.
Can I connect it to other climbing pieces?
Yes, the Play Cube can be used on its own or connected to other RAD climbing pieces. Adding a ladder or Reversible Climbing Ramp lets you build a slide, bridge, or pathway between structures.
What is your shipping and return policy?
Orders ship from a US warehouse, with free shipping on orders over $100. If it is not the right fit, we offer 30 day returns and our customer support team is happy to help.
