"My old chair was a fully adjustable ergonomic chair I bought seven years ago for $700. As someone who works 8 hours a day on a computer and then spends another 2 to 6 hours on the Internet at night, the chair is an important part of my life. I came to dread sitting in my old chair and felt it was draining the life out of me, but the SwingChair feels like a battery recharger and I can't wait to get back into it! Your invention is truly a stroke of genius. My legs and back get to move freely at any angle instead of being locked in an unnatural L shape all day. And your customer service is great! I ordered the chair on Monday and it arrived on Wednesday. Other chairs with headrests were going to take six weeks to special order."
