If you peek into any office, you'll likely see at least a few people at standing desks.

More and more offices are jumping aboard the standing desk bandwagon, from Australia's prime minister to the White House. Some studies say prolonged sitting isn't good for your health; others say standing improves group collaboration; and still others say sitting for hours is actually OK.

New Zealand-based Refold is yet another company to enter the game in an attempt to change the way we work. Its $250 standing desk is foldable, portable and recyclable — and that's because it's made of cardboard. (Other models, which are typically made from steel and wood, can exceed $1,000.)

You assemble the desk by folding it and locking it into place via slots within the cardboard, which is 0.2 inches thick. The desk can hold up to 187 pounds and can last an estimated one to three years, depending on how much you use it, according to the company. The small is 3.28 feet high; the medium is 3.45 feet; the large is 3.61 feet.

To transport your desk or store it, just fold it into a carry case — at roughly 14 pounds, it's lightweight for a desk. As a carry case, its dimensions are 43 x 26 x 3.3 inches.

If you're not ready to commit to standing 24/7, though, you can purchase it as a sitting desk with legs in New Zealand or Australia. Since the desk is made entirely out of cardboard, Refold also says you can customize it into a canvas. Take a look at one designed by the artist T-Wei, below:

Refold isn't the only portable standing desk out there, but most variations go atop your pre-existing desk — like StandStand, which folds up to the size of a laptop and is made from birch and bamboo.

A cardboard desk does have some obvious drawbacks. You could easily ruin it, for example, by spilling a glass of water or trying to transport it in the rain. (You can purchase one with a waterproof top for $300, or buy the waterproof top separately for $90). Still, you'd have to chuck the desk when it wears out. Plus, the person in the photos above looks like he's still craning his neck quite a bit; simply placing your laptop atop something tall doesn't have the same ergonomic benefits as a true tabletop desk.

So if you're going for inexpensive and easy, Refold is a solid option — but beyond that, make sure to weigh your options.
