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.

We added the Rectangles Add-On set to our Big Set, and it’s the perfect combination to make bigger structures that both of our kids (6&3yo) can be in at the same time. My 6-year-old came to me the other day to thoughtfully thank me for the add-on set, so what could be better than that?? Highly recommend! Gets lots of use at our house.

I bought a few of these packs for Christmas and everyday my kids play with them! I have a 5 year old and a 9 year old and finally they can play with a toy and not fight. They keep asking for more of them and they really play with this independently without asking me to do anything.

The product is well made and my grandson loves it. I find it a bite expensive for the number of tiles you get both with the big set and the expansion pack.
The big set should have atleast two additional rectangle panels and the expansion set should have one mor window/door panel.
As I said great product and I would buy again just feel it is expensive.

My daughter is very happy with the add on rectangles package!! We got her one rectangle package and her grandmother got her another rectangle package for her Christmas gift. She has used them everyday since then. She is 9 and tall for her age and she fits well inside of her forts she makes. We have no complaints about the product. They came within a few weeks after ordering, and we found a package with the price point that worked for our family.
- DKDaniel K.Verified BuyerReviewingSuperspace Rectangles Add-On Pack OrangeI recommend this productWhat is the age of the child or children? 6-8Rated 5 out of 5 stars2 weeks agoThe favorite of my grandchildren
These super space rectangles was a hit at a recent birthday Why can’t we let them meet the popcorn yeah that was after she let them in but is there a problem with him eating popcorn two different actions on my part. It expands dramatically the previous set that they had and they can make many more children’s size structures. They had their first structure up within minutes of opening the box..

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).
What are the box dimensions and weight?
40 inches x 20 inches x 4 inches. It weighs 13 lbs.
What countries do you ship to?
We ship to the USA, UK, and Australia.
For UK orders, visit the Superspace UK store.
For Australian orders, visit the Superspace AU store.
Does the Rectangles Add-On Pack work with The Big Set?
Yes! The Superspace Rectangles Add-On Pack is fully compatible with The Big Set, Little Set, and all other Superspace products. The magnets are the same strength and the panels are the same 9mm thick eco-felt material.
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.
