The CrossChair lets you change how you sit: switch from regular to cross-legged seating. Comfortably improve your posture!

About this project

The CrossChair reinvents the office chair, so you can sit cross-legged!

The chairs you sit in on a daily basis are a surprisingly personal item, with a tremendous impact on your health and well-being. I set out to build the CrossChair to give people a new option to improve posture, eliminate fatigue and reduce back pain: The option to convert the CrossChair from standard to cross-legged position can transform these hours of sitting into a positive and even healthful experience. Lets face it, many of us are stuck in a chair for long periods of time every day – whether for work or other activities. And it’s not all good. Conventional chairs – even expensive office chairs – lead to fatigue, back pain, slouching and slumped shoulders.

Sitting cross-legged is a great alternative: It is better for your posture, and keeps the hips and legs flexible. Many find it helps reduce or eliminate back pain caused by sitting for extended periods of time.

But there’s a problem: most adults can’t sit cross-legged in conventional chairs: Armrests are in the way; The chair isn’t deep enough to fit your feet; or (like me) you might lack the flexibility to actually bring your feet up onto the seat (into the same plane as your thighs and bottom) – much less be comfortable for more than a few seconds. CrossChair solves this problem, liberating anyone who sits a lot to benefit from the mind and body benefits of being able to change position and sit cross-legged. 

How the conversion works:

Switch from conventional to cross-legged instantly. You can change your position and posture as it suits you.

The CrossChair seat is divided into left and right sections. When converting to cross-legged seating position, the seat divides and the seating sections pivot open in a V-shape that supports your thighs when you cross your legs. Adjustable footrest: A padded footrest swings into place and fits into the V-shape between the seats, where you place your feet. The footrest can be raised and lowered depending on your flexibility and comfort.

Change is good - for your posture and your back!

Studies show that simply being able to change your seating position can eliminate or significantly reduce fatigue and back pain. The CrossChair converts from a standard to cross-legged sitting position. You aren’t stuck with one or the other.

The CrossChair encourages you to find alternative postures so you can keep changing things up, like this one:

Lap desk included! 

To complete the experience, the CrossChair includes a comfortable, padded lap-desk with the CrossChair logo which solves a key ergonomic issue of writing, drawing or using keyboard or tablet while sitting cross-legged.

 There are several challenging issues when sitting cross-legged related to use of a keyboard, laptop or tablet: Often, keyboard trays that are at the right height for conventional chairs can be too high and collide with the knees when cross-legged. In other cases when using a desk (without a keyboard tray) the surface is too high to type or write on, or it may be too far forward to reach comfortably. This CrossChair lap-desk solves this comfortably for our testers.

The design is wide enough to sit on the thighs with legs crossed. The bean-bag cushion allows you to position and angle it to your comfort. (Note - Many of our rewards include this CrossChair Lap Desk.) 

Sit in Sukhasana pose while you work

One of our goals with CrossChair is to transform daily sitting into an activity that helps people toward a therapeutic goal and increased flexibility. Yoga instructors will often suggest using a pad under the buttocks for Sukhasana pose (ordinary cross-legged sitting). Even more advanced and flexible people who can achieve the Lotus pose (with the feet pulled up onto the opposite thighs) may benefit from CrossChair adjustability. For example to help reduce pressure on the ankles the Foot Rest may be adjusted up high enough to rest the lower shins.  Both the Footrest provides eight height adjustments to ensure comfort even if you are inflexible, and if desired allows incremental adjustment over time to achieve greater flexibility. 

Our plans:

 Our goal for this Kickstarter campaign is to get the CrossChair into production and manufacture the first batch. This will require a “production” design, tooling, ordering standard chair components, and assembling and shipping the chairs. 

CrossChair Project Plan
CrossChair Project Plan

Here are a few more details on the main steps outlined on the schedule above:

Tooling: The longest lead-time item is the metal components of the seat frame. This will take about 12 weeks to design and build the tooling. 

These will be combined with some 'off-the-shelf' components such as the base, piston, wheels, upholstery sub-components, etc. We must order these "long-lead" items in advance.

Once the first run of custom components, and all standard components have arrived in stock, we can begin refining and testing the assembly procedures. 

Meanwhile we will design and specify packing materials and procedures.

Finally we can complete the first production run of chair and ship them! We are targeting mid-December 2014. The goal is to be done and ship before the Holiday season.

Stretch goals

If we achieve our basic funding goal for CrossChair, it will be available in black for the first run. On subsequent manufacturing runs will incrementally add an increasing variety of color options (e.g. white, tan, red, brown) and finishes such as leather, suede and similar synthetic options. (Note, if we exceed the goal, we may be able to create a stretch-goal to accelerate these color and finish options!). 

Rewards

We’ve got some great rewards to thank you for your pledge – including of course the complete chair, but also smaller pledge amounts that include a T-Shirt, and even a deluxe CrossChair Lap-desk. Check out the pledge-reward options on the right side of our kickstarter page for more information.

How it evolved

After the first inkling came to me after along day at the office (sitting, of course!), I began to make sketches. I built the first prototype at home in my garage, and began testing various features and dimensions.

A few prototypes later, we refined it to it's current form, which balances the right core geometry with a simpler more reliable design.

Biography

 My name is David McClintock and I love to ‘hack’ and improve things - especially when I encounter problems in my daily life. In addition to being a family man, I am an engineer by training, and have spent my career doing product management and marketing for products ranging from implantable medical devices, to embedded hardware, to software, Internet and mobile apps (most while sitting in a chair ;-). 

 After years sitting in a chair at office jobs and enduring chronic “sitting fatigue” and episodes of severe back pain, I conceived CrossChair and started to make drawings of the concept a couple years ago. I began to build my first prototype about a year ago, and have been iterating it ever since. I am most motivated by the prospect of changing the way people sit. This is one of those problems in life that is “hiding in plain sight”. How we sit is something we would never question. But after extensive research, I’ve found that here in the ‘western’ world I live in the current “office posture” is far removed from our biological needs, and from our ancestral origins. I believe this is one such problem that we can solve, together!

Risks and challenges

If CrossChair gets funded, we will ensure that all the steps will be completed for manufacturing. Since a chair is such a personal product, there are hundreds of attributes that affect a user’s satisfaction and comfort. Ordinarily a person would walk into a store and sit in several before choosing a chair to purchase. For this reason there is always the risk that people who purchase CrossChair online (as with some of our reward levels) will not find the chair an exact match to all their desires. However, we are confident that the benefits of the CrossChair design (the conversion and adjustments for sitting cross-legged) will far outweigh these subtleties. Moreover, going forward we will introduce a variety of models that cover the most popular ‘fit and feel’ attributes to satisfy almost any customer. I hope you will join us in this brave venture to change the way the world sits!
