Frequently Asked Questions

How big is the UnChair? The UnChair actually takes up less space than your typical rolling office chair yet is more spacious for floor-sitting postures. It measures 22.5" x 22.5" x 13.5" (57.2 cm x 57.2 cm x 34.3 cm).

How much does the UnChair weigh? The UnChair weighs about 15 pounds (6.8 kg).

What's the UnChair made of? The UnChair is made of birch plywood and has solid rubberwood legs. It's upholstered with high-density EVA foam and waterproof canvas, creating a wonderful balance of plushness and firmness for floor sitting.

How much weight does the UnChair support? The UnChair hasn't been weight-tested to failure, but it has easily supported 200 pounds (90.7 kg) in our testing.

How do I get on/off the UnChair? Please take care when mounting/dismounting/changing postures on the UnChair. It's lightweight for its size, so it's best to keep your weight close to the center for stability. You can try sitting down/getting up "hands-first": grip the edges of the seat, center your weight, push off with your palms, then follow with your feet. If it can support it, you can also push off of your desk/table surface a bit while you adjust your posture.

How did you decide on the height? We designed the UnChair to accommodate floor sitting postures at your typical desk or table, which is 28"-30" high. Most chairs sit around 18" high, but the UnChair's slightly shorter height provides room for props and your knees/thighs under a desk or table.

How do I clean the UnChair? The waterproof canvas seat covering can be wiped clean with a damp cloth and mild soap, or a wet wipe.

Why is there no backrest? The UnChair is designed to promote active sitting. Most chairs nowadays have backrests, but studies show that that can be part of the problem with conventional, prolonged sitting. We've found it too easy to become dependent on conventional backrests (and armrests) to hold up our torsos and to start slouching, “veg out,” and forget that we have bodies that move and breathe. This results in reduced muscle engagement while sitting, which can lead to muscle weakness and chronic pains over time. The UnChair is perfect for practicing awareness of breathing, posture, and alignment (like meditation!).

Why are there no wheels? Contrary to what most office chairs would have you believe, you don’t actually need a chair that moves - you need a chair that lets YOU move! The UnChair is designed to promote active sitting and muscle engagement to make sitting a healthier activity. While most office chairs move you around and cradle you so you don’t move a muscle, the UnChair stays where you want it so you can move around it. The UnChair is light, though, weighing about 15 pounds, and has felt pads on its feet to protect your floors and enable easy maneuvering while also limiting distracting or unintentional movement.

Why wouldn’t I just sit on the actual floor? Go for it! (The UnChair also makes a great floor desk or tea table!) Floor sitting, with its time-tested benefits and versatility, is the very inspiration behind the UnChair. The UnChair, though, is designed to bring additional comfort and modularity to the floor sitting experience and bring it up to typical desk/table height, for the situations in which an elevated workspace is desired.

Why can’t I just slap a mat on my coffee table and sit on that instead? While we wouldn’t recommend it, given that most coffee tables aren’t built to be sat on in terms of stability, strength, and comfort, we dig unconventional sitting! Unlike a coffee table, though, the UnChair’s sturdy construction, foolproof design, smooth edges, and upholstered seat cushion make it purpose-built for any kind of sitting you can imagine.
