OUR STORY
A simple need started everything: a comfortable way to sit at high altitude without the burden to haul it there. We refused to accept that taking in the view meant weighing down the journey.

Frequently Asked
Questions

What is the size and weight when stowed?

The packed stuff sack measures 14” long and 2.5” in diameter, with a combined weight of 8.1 oz. The Antimatter Chair by itself is 7.0 oz.

How do I set it up and/or stow it?

We understand that the design is a bit of an origami puzzle, but we hope this video we made helps you better understand the design.

What are the magnets for?

We received a lot of feedback from the early Antimatter prototype testers that the chair was too flimsy and unstable in the moment between chair setup and weight application. Therefore, we added some small magnets to the chair base and chair back support poles to help them snap into position and maintain alignment during deployment. Don’t worry if they naturally separate while sitting on the chair, we designed them that way so they don’t prohibit the chair from adjusting to your preferred seating orientation.

Is it suitable for different types of ground?

Yes! We’ve designed and tested the Antimatter Chair to work on grass, dirt, mud, beach sand, etc. More so, the feet of the chair will not puncture or damage the bottom of tent floors, foam mats, or sleeping bags, so it’s perfect for INSIDE of tents!

I’m trying to cut ounces, do I need the stuff sack?

Nope, if you don’t need it, leave it at home. A simple rubber band can keep the Antimatter wrapped up tight to stow in a backpack sleeve.

Is this really a chair if it sits on the ground?

Call it whatever you want, but your back is going to be calling it “sweet relief” after a long day of trekking.

Can I use it on damp or wet ground?

Yes, the bottom fabric layer is polyurethane (PU) coated and will provide a degree of waterproofness. However, this thin layer of fabric does virtually nothing to insulate you thermally, so if the ground is cold we recommend adding an insulated cushion into the mix.

Do you ship internationally?

Sure do! However, additional shipping fees may apply. If your desired country of destination is not available through our webstore, please contact us to have it added.
