A few days ago I posted a review of the Varidesk Pro Plus standing desk. I’m enjoying the versatility of this desk and the ability to easily go from standing to sitting in just a few seconds. But after a couple weeks of standing, I’ve started noticing some problems with my knees hurting from standing in one place all day. Enter the FluidStance Level, a new crowdfunding campaign on Indiegogo, a specially designed “surfboard” for people who use standing desks. The Level solves the problem of standing in one place by giving you a deck that you stand on that allows you to balance, shift and pivot position. The Level is made with a wood deck and an aluminum frame on the bottom. You can pre-order a FluidStance Level for $289 through their Indiegogo project page. Shipping is estimated for May. The project has 6 days left till the campaign ends, but it’s already surpassed the funding goal many times over.
