Let's cut to the chase: The chair doesn't defy gravity. Even with all the massage elements running and in full recline, you're not going to fly off into the atmosphere. Nor does the chair hover, float or even lose weight. In fact, according to the user's manual, the chair weighs 200 pounds (90.7 kilograms) [source: HT-7450 Manual]. So what does it mean if a massage chair is a zero-gravity model? It has to do with the recline position the chair can assume. The position mimics the posture astronauts take during liftoff on space missions. Because astronauts endure intense and sudden increases in gravity while escaping the Earth's gravitational pull, it's important that they position themselves so that their bodies can deal with the increase in stress. By assuming a reclined position, astronauts distribute the stresses of takeoff across their bodies in a safe way. To that end, the chairs astronauts sit in during launch use this reclined configuration. Zero-gravity massage chairs can assume the same position to help distribute a user's weight across the chair.
The manufacturers claim that this relieves stress on the body and allows for a deeper, more intense massage experience. Some manufacturers claim that the reduction of stress on your body is so effective you'll feel virtually weightless as a result. While several massage chair manufacturers offer models that come with the zero-gravity position feature, not all zero-gravity chairs are massage chairs. Some furniture manufacturers offer normal chairs that recline into the zero-gravity position. The chairs distribute your weight and support you, but they won't rub away your tension and stress. Other manufacturers stop short of making that particular claim. Instead, they say that the chair replicates the launch chairs for astronauts. They call their chairs zero-gravity not because of the effect the user feels, but because of the position the chair assumes when activated. One benefit of this position is that it promotes circulation in the legs and reduces swelling. Elevating the legs over the level of the heart during rest can help prevent conditions like varicose veins [source: VascularWeb].
Of course, you could achieve the same effect by lying down and putting a couple of pillows under your legs. But that's not quite as impressive. During the author's massage experience -- yes, the author was the weary journalist mentioned earlier -- there was no sensation of weightlessness, but the reclined position was comfortable and did allow for an intense massage. Because the author's back was in full contact with the chair's backrest, the full force of the chair's massage routine was effective. An upright position might not allow the intensity and thoroughness of a massage in the reclined position. Are zero-gravity massage chairs worth the expense? That's a decision best left to the consumer. Some people might think the chair's convenience and effectiveness makes the expense completely justifiable. Others might prefer to see a human massage therapist -- $4,000 could buy a lot of visits to the spa. To learn more about massage chairs and related topics, take a look at the links on the next page.
When it comes to sitting in an office all day, I really have no idea how I'm supposed to work. Sitting at a desk is going to kill me. But standing all dayAnd now new research maybe sitting isn't so bad after all. Studies on the occupational hazards of working in front of a computer have been trickling in for years, and the results are Still, people are abandoning the simple task chair and desk combination and swapping them for standing desks, kneeling desks, treadmill desks, and everything in between. One fact remains, however: Being in any kind of static position for extended periods of time is bad for you. So when my colleague mentioned in passing this "lying desk," I figured why not give it a try? I'm going to be in front of a computer all day anyways — why not be extremely comfortable? The typical client of one of these things is a professional who uses a computer all day, but who is becoming less productive
because of pain, Jeff Vanden Bosch, president and principal designer and engineer at ErgoQuest, told Tech Insider. When reclined in a stress-free, zero-gravity position — with the torso and thighs aligned and the legs extended above the heart — Vanden Bosch said, it can "reduce pressure on the spine and lower back, reduces stress on the heart, relieves muscle tension and back pain, and increases lung capacity and blood circulation." Vanden Bosch initially designed the Zero Gravity Chair to help people with disabilities or physical limitations — such as thoseneck, spine, and lower back pain; or those in wheelchairs.

Getting into the chair was a bit of a nightmare. monitors and keyboard were fully set up, maneuvering into the seat without smacking my head and side on the monitors or keyboard tray was challenging. But the moment I settled in and began reclining — around 10 a.m. — the tension in my legs immediately lifted. sense of calm and relaxation floated over me as I settled into "You can't fall asleep today," Dave Mosher, my deputy editor at Tech Insider, said casually as he swung by my station. Once I locked myself in and got over the overwhelming sense of calm, I took my boss' quip as my cue to start tackling my writing ErgoQuest supplied me with a few strips of double-sided sticky tape to lock my keyboard and mouse pad into place. strips on the mousepad, which meant I had to MacGyver my own way of sticking the keyboard down.

If I was smart, I'd have surrounded myself with snacks, but now I was stuck. of pulling myself out of the chair was more overwhelming than staying put and dealing with my hunger. I even considered asking my editor to feed me grapes ancient Greek king style, but considering his earlier remarks, I decided This is the position I was in for the entire day. Once I finally did manage to procure a pile of snacks and a refill on coffee, I then faced some new fears. What if I choked on a rice cracker? What if I spill hot coffee all over myself? "What if there's a fire?" Kevin Reilly, Tech Insider's videoI hadn't even thought of that. Then, about 20 minutes after I got in, I had to pee. Pal when I need it! I eventually got over my immediate anxieties and really started
At first I was acutely aware of myself trying to work while lying on my back, which was pretty distracting. But after a few hours, I completely settled into the full immersive experience of being in a tech cocoon. This chair would be perfect for gamers. Next thing I knew it was 3 p.m. and I hadn't eaten lunch — or moved at all for that matter. I normally scarf food down at my desk while I'm working, but what am I going to do — eat on my back? Only this sloth has mastered I pulled myself out of the chair, heated up my lunch, and ate at my regular standing desk. It was nice to feel like I was sort of exercising for a second. Then I immediately got back to work, on my back, which I only imagine would inevitably lead to heartburn if I did this on the regular. I eventually found my groove and became somewhat productive — though definitely not more productive than usual. asleep despite my overwhelming sense of calm.
I also didn't feel any tension in my body — a nice departure from my regular I felt as if I were in a cave of sorts, able to tune out the chit chat of our open office. I could see how the chair could dramatically help people work while managing back problems. My shoulders were relaxed, my legs But I don't think I'd ever want to work in one of these thingsFor one, it takes up way too much space. people, it is prohibitively expensive. Being immobile and on my back also did not jive well in an openI couldn't move around, collaborate with coworkers, pop in and out of meetings, and take phone calls. The only case I'd see this working out is if I had a home office, but even then I think I'd still feel trapped. I reached out to Jen Horonjeff, an ergonomics and biomechanics consultant in New York, and she agreed with my assessment. "While the Zero Gravity Workstation from ErgoQuest is highly adjustable, it seems to neglect that humans are ambulatory
creatures," Horonjeff told Tech Insider. Perhaps most importantly, the lying desk doesn't solve any of the occupational hazards associated with working at a regular desk — while there is less stress and tension on the body, you're still sitting in one position all day, which is very bad for your body. "One of my concerns with the Zero Gravity Workstation is that it encourages a fixed position," Horonjeff continued. could spend hours in this reclined position before some other reason or stimuli persuades them to get up. movement, with the research showing we should be taking micro breaks to shift postures at least every 30 minutes, and I am afraid this chair does not promote ease of changing postures." Luckily I didn't have to do any phone interviews, but I think it would've been a nightmare if I had. Interviewing scientists on my back would probably not promote the most enlightened discussions. And the thought of adjusting my position to be upright while
navigating all of the wires and monitors made me want to die. I asked Horonjeff if she would recommend that people use this workstation. "I would not," Horonjeff told me. individuals a false sense that they are doing themselves a favor by working in a zero gravity position, when in fact there are several risk factors associated with using this So what's a good alternative? "For that price, you could buy yourself a highly adjustable ergonomic task chair, hire an ergonomist to educate you on neutral postures and custom fit your workstation, and pay for a gym membership for a year," Horonjeff said. "We need to be more thoughtful about our choices and know there is no panacea or quick fix for our workstations."While the Zero Gravity workstation was a luxurious departure from my standing desk, working like that every day would bring more challenges than benefits.
