A company called Wilkhahn created a calorie-burning piece of office (or home office) furniture called the ON Chair. This baby offers a full range of motion, allowing you to move forwards, backwards, and side-to-side, putting your knees and hips to work while you toil at your desk. Check out the video above to watch people try the ON on for size.

The ON Chair can activate your metabolic system (so says a German health institute) and prevent pain, improve posture, cure cancer, etc. Plus, it maintains a stable center of gravity the whole time, meaning you never have to worry about falling over – which, we’ll admit, we were worried about.

The ON Chair cost $850 as of last fall – would your boss cover that?

In home décor, family heirlooms and antique pieces are wonderful ways to add character and class to any room. Investing in a whole set of antique furnishings is beyond most homeowners’ budgets, but it’s possible to achieve the same effect with a couple of smart purchases and design decisions.

To begin, you only need one really great piece of furniture, which you can find online, at antique sales, or maybe even from a relative. This can be a loveseat, armoire, desk, whatever you want—just make sure you enjoy everything about it, from color and pattern to texture and shape.

From here, it’s time to flex your creative muscles. To best showcase your new antique, you want to echo its form, style, and materials in your selection of the room’s other pieces. For example, if your antique was a beautiful leather loveseat with dark wooden legs, you could echo the legs by purchasing a new bookcase of the same material and shade, or even by staining an item you already own.

Find a few more echoing pieces, and you’ll soon have a cozy, traditional room centered around a single antique item.
