    Frequently Asked Questions

    It's perfect for children aged 3+ and even loved by older kids and adults!

    The Superspace square panels are made of an amazing material called Eco Felt, which is made from recycled plastic bottles! This gives the panels resilience, durability, and ease of cleaning (we suggest using a damp cloth).

    Simply wipe them down with a damp cloth. The eco-felt material is designed to be durable and easy to clean.

    Yes, the magnets are securely housed in a kid-proof casing and comply with all safety standards.

    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.

    All of the panels are 9mm in thickness. The sides of the squares and squares with windows are 20 inches (500 mm).

    40 inches x 20 inches x 4 inches. It weighs 13 lbs.

    Currently, we are only shipping to the USA and UK. We hope to expand our shipping options to other countries soon.
