Laptops and tablets spur mobile productivity, and the growing options for standing desks have addressed better posture and overall body health while working. The latest all-in-one solution combines the best of both worlds. The portable Edge Desk is designed to pop up a kneeling chair and adjustable work surface, folding down flat to save space when not in use.The Edge Desk comes fully assembled and can be deployed in under 10 seconds. The frame, which looks like a cross between a portable massage chair and art easel, is made out of aluminum. Padded cushions provide comfortable support as users sit in a kneeling position.
As such, the Edge Desk encourages proper upright sitting instead of the hunching/slouching posture typically associated with fatigue and lower back pain.Designed to accommodate to the user's ideal comfort level, the Edge Desk's height, angle and tilt are adjustable to suit individual body size and desk preferences. The white work surface, which measures 20 x 30 in (50.8 x 76.2 cm), can swivel between landscape and portrait orientation as desired. When done, the Edge Desk collapses down to 6 in (152 mm) for easy storage against walls, in closets, or under other furniture. Because it's so compact and weighs only 25 lb (11.3 kg), this desk can be carried with one hand and/or tucked away in a car trunk. In addition to its flexible form, the Edge Desk offers modular functionality through a patented groove feature. The company plans to create accessories that are designed to snap into the sides of the work surface. Users may expect add-ons such as a cup holder, pen/pencil tray, tablet/smartphone/paper stand, LED light, speaker, and more.
Each of these accessories will fold flat while maintaining the Edge Desk's slim profile.The Edge Desk is currently funding on Kickstarter, having raised 118 percent of its US$165,000 goal in 10 days, with another 36 days left to go. A pledge of $299 sets you up with one Edge Desk, saving 40 percent of the planned retail price.Over six prototypes have been designed and field-tested. So if final engineering, tooling, and production go according to schedule, backers can expect shipments of the Edge Desk to start sometime this October.Sources: The Edge Desk, KickstarterThe wrong chair = real health problems. (Total read time: 8 minutes) In this post I’ll cover how I identified the best high-end chairs in the world, which I ultimately chose, and the tangible results that followed. In January of 2005, I found myself on a veranda in Panama after the usual afternoon rain, dreaming of the upcoming year and reflecting on lessons learned since leaving the US. Maria Elena, the matriarch of the Panamanian family that had adopted me, sipped her iced tea and pointed at my bruised feet:
“Tim, let me share some advice I was once given. Buy the most comfortable bed and pair of shoes you can afford. If you’re not in one, you’ll be in the other.” I followed her advice upon returning to CA and the results were sudden: Plantar Fasciitis disappeared, as did shoulder impingement after switching from coil-spring to foam-layered mattresses. But what about chairs? On January 4th, 2009, I tweeted out the following: “Is the Aeron chair worth it? http://tr.im/2uxd Do you have any fave chairs for extended sitting and writing?” Even though I’m financially comfortable now, I didn’t grow up spending a lot of money, which I’m thankful for. To this day, I’ve never paid for first-class airfare for myself. Not that it isn’t worth it — I just can’t do it. Similarly, I had trouble believing a chair could possibly be worth $850-$1,200, but my back pain led me to pose the question to the omniscient Interweb. More than 95% of Aeron users replied with “yes, absolutely”, but it wasn’t the only chair with a cult-like following.
Four of the five are manufactured by Herman Miller (HM) and Humanscale (HS). Prices are from Amazon, as are the star reviews, but discounts of $200-400 can be negotiated with dealers. Both eBay and Craiglist offer similar discounts. In descending order of popularity: 1. Aeron (Fully loaded) (HM) – $879 (1 review; average review: 5 stars) Used at NASA mission control and tech start-ups worldwide.2. Mirra (fully loaded) (HM) – $829 (14 reviews; average review: 4.5 stars) Note: the Herman Miller sales representatives I spoke with preferred the Mirra seat feel for shorter legs vs. the Aeron. Easier to adjust: Mirra is about 9 revolutions from loosest to tightest settings; 3. SwingChair – $495 Recommended by a strong contingent of writers, including one of my favorite visual storytellers, Kathy Sierra. I like the design concept, but I would suggest other forms of “core exercise”. 4. Liberty (HS) – $899 (6 reviews; average review: 3.5 stars) 5. Freedom Task Chair with Headrest (HS) – $999.99 (1 review, average: 4 stars) Used at the FBI and by other governmental agencies with three-letter acronyms.
6. Embody – $1,800 list price (negotiated with dealer: $1,200-1,300): Basis of chair design – sitting is bad; Even in locked position, it still has some backward flex at the top position. No forward tilt option. For personal testing, I also added a Swiss-ball chair (Isokinetics Balance Ball Chair – $75) to the mix, as seen below: Surprisingly, the Isokinetics chair is more comfortable than most fixed chairs I tested, though there is some minor… ahem… testicular compression that isn’t nearly as pleasant as it sounds. If you don’t have jewels to worry about, this chair could well be an ideal cost-effective choice. The chair I most wanted to test was the Mirra, which seems to have the best combination of price point (bought used or via eBay) and multiple 5-star reviews. Not to mention it’s also the name of one of the best BMXers of all time. In the end, I bought a used C-size (technically a bit too large for me) Aeron for $450 on Craigslist. I’m impatient and didn’t want to wait over the weekend to schedule sittings for other Herman Miller chairs with a certified dealer.
Once I have some conclusive comparable data, I want closure.I’m 5′ 8″ and 170 lbs., but the C works with no problem. 1) The lumbar support is — by far — the primary determinant of comfort or pain. I’ve lowered this adjustment and found that maintaining the natural S-curve through pressure on the lower back is what prevents pain most consistently. Comfortable sitting time is now 7-8 hours vs. less than 2 hours, with no ill after-effects. Sliding lumbar support on the Aeron. 2) Seat height (and secondarily, depth) will determine the rest. If the flats of your feet don’t make complete contact with the floor, you will move your hips forward and slouch, eliminating the S-curve in the lower lumbar. If your seat is too low and your knees are above your hips, you will shorten the habitual range your hip flexors (negative neural adaptation) and end up with severe lower-back pain. Aim to keep your hamstrings parallel to the floor, and if the seat is too long for your femur (thigh bone) — as is mildly the case with my C-size Aeron — just separate your knees a bit.
If you’re not wearing a tight skirt, I’ve found a basketball of space between the knees to provide the best lateral stabilization, which reduces torso fatigue. Take off heels when sitting at a desk, lest you end up with hot calves and Quasimodo-like posture. Not good for mating. If you are wearing a tight skirt, I suggest taking up the Japanese tea ceremony and sitting on tatami side saddle. It’ll be more comfortable than crossing your legs all day.True, I’ve thought more about chairs in the last few weeks than anyone should, but I do it to save you the trouble. Benefit from my OCD so you can obsess on other things. 3) Using a 3′ long and 6″ diameter foam roller three times per day for 5 minutes can eliminate persistent middle-back pain from mediocre chair use; conversely, it can extend your comfortable sitting time by 30-40%. Knowledge workers often log more ass-in-seat time than sleep. Coders, in particular, are often subjected to a steady diet of Mountain Dew and hunching for 12+-hour marathons.
I don’t put in these hours, but I found myself with severe mid-upper back pain from using a non-adjustable chair and craning over a desk that was too low, even for 30-60 minutes per day. Two doctors suggested various therapies, but a quick experiment (placing a laptop on top of a dresser and writing while standing for two days) proved that posture was the problem. In less than a week following my switch to the Aeron, all upper middle-back (lower trapezius, rhomboid major) pain disappeared completely. The results: better output during work and writing, faster and deeper sleep, and a huge smack on the forehead. Why the hell didn’t I do this earlier? In my case, was it worth it at $450? Particularly looking at the value of time per hour and the lost income due to doctor visits, massage, etc., this is $450 I should have invested years ago.
