Research by Cornell professor Alan Hedge shows a strong link between productivity and workspace design -- the kind of chair you sit in, the height of your desk, and so on.
Cost-conscious telecommuters often skimp on these items, says occupational therapist Ellen Rader Smith, only to end up with back problems later. Don't be one of them.
Use the upgrades here exclusively for work, and you can deduct the cost, says CPA Donald Duncan (exception: the treadmill).
The Herman Miller Embody chair ($1,199)
Both ergonomic and stylish, this seat conforms to your body and distributes weight evenly to relieve pressure on your lower back. Sure, it's a tad more than $1,000, but your back will thank you.
The Geekdesk Max ($949 to $985)
Forget the chair entirely. This workstation, which can be raised up to 49 inches, allows you to stand while you type. A recent study found that you can boost life expectancy by two years if you sit for less than three hours a day.
The TrekDesk and a compact treadmill ($479 + $500)
Forget standing still. Keep moving with this specially designed desk that fits over most standard treadmills -- allowing you to walk off your frustration while checking your endless e-mails.
If you have an extra $10,000, options abound for you to boost the value of your home, give to charity or take off on a cheap European vacation.
