Montessori Cube Chair

Montessori Cube Chair$115.00

The Montessori Cube Chair is a versatile weaning chair designed to support independence, comfort, and development from infancy through the toddler years. Thoughtfully sized for young children, it creates an inviting space for mealtime, play, and early practical life activities.

The Cube Chair can be introduced once a child is a strong sitter, typically around 6 to 9 months old. Its two primary seating heights, 5 inches and 7 inches, pair perfectly with RAD 13 inch Toddler Height Tables, making it an ideal first chair for early meals, play, and exploration. As children grow, the chair flips into an 11 inch stool that works well with a 19 inch Preschool Height Table, extending its usefulness into the preschool years.

Handmade in our shop from premium Baltic birch wood, the Cube Chair reflects RAD’s commitment to sturdy construction, thoughtful design, and quality materials. Despite its compact size, it supports up to 150 pounds, making it stable, durable, and suitable for shared moments between children and adults.

The solid back provides postural support, while the integrated side handle allows children to move the chair with confidence and practice aided movement. The simple, intentional design also supports self dressing skills, giving children the stability they need to practice putting on socks and shoes independently.

The Montessori Cube Chair ships fully assembled and is ready to use right out of the box.

When can I expect my order to arrive?

Shipping estimates are available on each product page. These indicate when the item will be shipped from our woodshop in Los Angeles. Domestic orders are shipped via UPS Ground, and transit may take up to 5-7 business days depending on your location. Please note that our team does not operate on weekends and federal holidays. Orders placed on these days will be shipped on the next business day.

Is assembly easy? Tools? How do I assemble?

Our furniture requires minimal assembly, needing only an Allen key, which we provide along with online instructions. If your order includes over 20 screws, we'll also include hex drill bits to make assembly quicker. An electric drill could be useful but isn't necessary. You can find all our assembly instructions here.

How should I clean for my RAD furniture?

To clean your furniture, use a non-toxic mixture of vinegar and warm water. Spray the surface and immediately wipe it dry with a clean cloth. Never soak or immerse wooden furniture in water as it can cause the wood to swell and deform.

Can I use my furniture outside?

You can use your furniture outdoors but don't leave it outside for longer than necessary, as it's not designed to withstand extended exposure to outdoor elements. After use, wipe down the surface with a dry cloth. Leaving your furniture outside may void your warranty.

What is your policy on returns and exchanges?

We accept returns within 30 days of delivery for unused products in their original packaging. If you receive a damaged or defective item, contact our support team within 7 days of delivery for an exchange or replacement. Please note, customized or assembled items are non-returnable.

Loved, Lived, and Shared by Parents

Because nothing says it better than real play in motion.

Customers praised this sturdy, well-made toddler chair for its quality craftsmanship and versatile cube design with multiple height options. Shoppers loved that it "came assembled" and is "light enough to be moved by a determined toddler." Many appreciated the ergonomic design and smooth edges. Some noted sizing considerations for taller children.

Great purchase!

Bought this to go in my daughter’s play room and it’s been perfect!! Highly recommend!

Thank you so much for taking the time to share your feedback and photo! It's lovely to see your daughter enjoying her new table and chair. We hope it brings her years of fun and creativity! ❤️

Cozy ergonomic seating for our little one

I love watching my kid use these chairs because they are so intuitive and ergonomic for little hands. She is able to move the seat to where she wants it and it slides perfectly under the matching table when not in use. I think the cube design makes it structurally sturdy so when she stands on the chair, I am not worried about it tipping over. I also love the 3 height options of using it so we can have it for many years! Most importantly, YES to supporting small US businesses!x

Thank you for your kind words and for sharing this lovely moment with us. It’s wonderful to see your little one enjoying their chair. We appreciate your continued support and are thrilled that you're happy with all your RAD furniture. :)

Love the Cube Chair

I got the cube chair for our 6-month-old to use as a little desk. I'm excited that he will grow with this piece - from desk to chair to stool.

My 16 month old loves climbing in and out of his cube chair! We set up a “work” corner for him in our work room to encourage independent play while I work. Item came well packaged, and quite quick!

Love every piece!

I own a toddler school and love every piece of furniture purchased. These chairs came assembled and are the best quality. John and his customer service team are truly the best. I keep coming back for the quality, customer service, fast delivery. I wouldn’t order anywhere else for classroom furniture.

Thank you for the kind words! One of the best parts of this job has been building relationships with educators like you and providing furniture for your classrooms. We truly appreciate your continued support of our small shop. :)

Well constructed; baby adores it!

This chair is excellent. Very solid, but still light enough to be moved by a determined toddler. My baby was absolutely delighted to receive furniture that’s just her size. I would recommend this piece to any parent!

Thank you for taking the time to leave a review. We are thrilled to hear that your child is enjoying their very own sized chair. We appreciate your recommendation and hope it continues to bring happiness to your family. :)

Anne (Strongsville, US)
Granddaughter loves it!

My granddaughter loves it. She is two years old and carries it around with her to every room she is in. She reads in it, uses it at her art easel, and many other things. It is very well made and all the edges are smooth so they won’t scratch her or the floor. I love that she can use it as she grows. 100% would recommend it.

A place to learn…and snack!

These pieces of furniture are functional, beautiful and well made. They are made to support a child’s development—not to look cute and be uncomfortable in actuality. These are furnishing that facilitate learning. As an early childhood educator, and mother of a toddler this was exactly what I was looking for without having to purchase industrial school-grade furnishings which often are heavier and less eco friendly. So glad I got the table and cube chair.

Beautiful and well-built chairs. We ordered 2 to go with the square toddler table and now my brother-in-law is jealous and wants his own.

Seslie (Dripping Springs, US)
Rad cube chair and toddler square table

We purchased a cube chair and the square table for my son’s 1st Birthday! He loves it and enjoys eating his snacks at his new weaning table. I am a Montessori Lead Guide and I really love the quality of Rad Children Furniture. Definitely plan on purchasing more furniture to support my child’s independence in our home!

Cube chair and table

Very high quality product!

L
Lee (Chicago, US)
Great chair - he loves it!

Our son absolutely loves his chair. Very high quality and looks great with his table. Recommend checking the height instead of just using the age on the chart. If exceptionally tall for their age the chair will be short.
