Award Winning Toy Design
Make Room for Big Ideas
Sometimes a single rectangle just won’t cut it, especially when your child’s imagination is going vertical.
The Superspace Rectangles Add-On is made to amplify builds, turning cozy forts into castle towers, tunnels into mazes, and hideouts into hero HQs.
It’s designed to grow with your child, whether they’re into epic pretend play, cozy reading corners, or building spaces to just be.
Bigger panels = bolder ideas.
Best of all? It slides right into your existing Superspace set with no extra setup, no extra mess, and endless new possibilities.
Smart Play That Feels Like Fun
Every rectangle is more than just a shape, it’s a gateway to STEAM learning.
Kids naturally explore balance, proportion, and spatial thinking. That “window” panel? It's a portal to storytelling, creativity, and even role-play.
Perfect for sparking independence, problem-solving, and confidence.
No rules, no instructions, just pure creative freedom.
And yes, it all folds away easily (parent magic).
Peace of Mind Built In
We get it. Your home is already full of stuff. That’s why the Rectangles Add-On Pack is lightweight, compact, and built to last.
Made from recycled plastic bottles, these eco-felt panels are soft to the touch, sturdy for serious play, and a dream to store.
No mess, no noise, and zero guilt over another “plastic toy” collecting dust.
Whether it’s a rainy day build-a-thon or a sunny afternoon on the patio, these panels handle it all.
Indoors or out, they’re made for real life and real families.
Why the Kids (& Parents) Love Superspace
I originally purchased the Big Set for my grandkids' birthdays. These were a big hit, so I bought the Rectangles add-on pack for Christmas. Now they can build such amazing things. Any kid who comes for a play date loves these. I HIGHLY recommend them. My grandson is 4, and my granddaughter is 2. I'm truly so happy with these purchases!
We bought the big set and added the rectangle set for Christmas and my kids play with it constantly. It's perfect for my 2 year old and my 6 year old. They play for hours and use their creativity to build unlimited structures.
My kids LOVE their rectangle add on set with the regular 24 piece set. This was a perfect gift that will get many years of use! Stability is good and it's easy for a 5 and 7 year old to put together by themselves.
All my kids (3, 5, 9, and 11) all love these but this add on is a must for the older kids to be able to use it/fit. Even just my littler guys appreciate them a lot though too.
As a mom I got tired of the constant fort in my living room. This set was a huge hit and now our forts move throughout the house. It's all easily stored under my child's bed. Every child that comes over loves to play and build. Thanks for a cool product.
The rectangle add on is a must. It allows many more builds and my kids absolutely love them!
Now we can build taller and bigger forts. Kids love it!
If you are on the fence, just do it. Superb quality and endless possibilities. Perfect add on to base set.
Perfect addition to the Big Set of 24 tiles. Dramatically increases the possibilities.

Frequently Asked Questions
What ages is the Rectangles Add-on Pack suitable for?
It's perfect for children aged 3+ and even loved by older kids and adults!
What's included in the Rectangles Add-On Pack?
The Superspace Rectangles Add-On Pack includes 6 rectangle panels (40" x 20" each) and 1 rectangular window panel. All panels are made from eco-felt and feature auto-aligning magnets on all edges.
What are the Superspace panels made from?
Our magnetic tiles are made from eco-felt crafted from 130 recycled plastic bottles per set. This material is durable, easy to clean with a damp cloth, and softer than hard plastic tiles.
How do I clean the tiles?
Simply wipe them down with a damp cloth. The eco-felt material is designed to be durable and easy to clean.
Are the magnets safe?
Yes. All magnets are securely housed in kid-proof casings. The Big Set is CPSC (US), UKCA, and CE certified for ages 3+.
Is your product child safety certified?
Yes, Superspace satisfies the UKCA and CE, the official standards for children's safety in the USA and the UK. We take child safety very seriously because of the magnets. Our unique secure magnet casing system makes it extremely difficult to remove the magnet, even if the casing is taken off the panel. Should the magnets be ingested, though, it would be harmful. We recommend that parents frequently inspect their Superspace for any loose or broken parts, and remove any panels that have broken from their children.
What can I build with the Rectangles Add-On Pack?
Rectangles are perfect for building taller structures, larger enclosed spaces, walk-through passages, and more complex fort designs. Kids love using them for castle towers, rocket ships, reading nooks, and mazes.
What sizes are the Superspace rectangles tiles?
All of the panels are 9mm in thickness. The sides of the squares, squares with windows, and triangles are 500mm (20 inches). The long side of the Trapezoid and Rectangle is 1000mm (40 inches).

Do I need The Big Set to use the Rectangles Add-On Pack?
Yes, the Rectangles Add-On Pack is designed to expand an existing Superspace set. We recommend having The Big Set or The Little Set first, then adding rectangles to expand your building possibilities.
