In our connected world, many people now work remotely from home, spending hours at a time parked in front of the computer. In fact, even if you commute to work—or even if you're retired—chances are that you spend a sizable portion of each day in your office area, sitting on a desk chair. If long stretches of time on that chair leave you with nagging aches and pains, it may be time to replace it with something more ergonomic. At the high end, options abound, but relatively offer enhanced comfort at a low price. With its adjustable seat, mesh back, lumbar support and lockable tilt function, the MARKUS swivel chair may be the best of the budget bunch. Available at IKEA; $199.
