Flexispot M3 47" XL Standing Desk Converter

Flexispot 47 Overview

The FlexiSpot M3 Standing Desk Converter is the perfect desk for users with extra large monitors, or who just need more work space on their desk riser.  At 47 inches wide x 24 inches deep, the upper work surface of the M3 is almost like having an entire desk move up and down with you, which means ALL your work can move up and down with you, as you move from sit to stand.  The M3 should easily fit two 27" monitors, two 32" monitors, or 2 smaller monitors and a laptop.

The M3 also features extra strong gas springs designed to support more weight than the standard desk riser - up to 45 lbs weight capacity - which makes it a great option for users with heavy monitors, or triple monitor arms.

And unlike other popular standing desk converters that swing away from your desk in the top position, the Flexispot M3 adjusts straight up and down - allowing you to stay close to your work and maximize your desk space (and avoid dangerous tipping).  The lifting motion is smooth and easy, with twelve height adjustment settings up to 20" high - ideal for taller users over 6'.  The M3 also comes with a dedicated thru-hole for safely mounting monitor arms and stands of all types.

*Now with a new, larger keyboard tray!  (no more sliding keyboard tray)

Waited Too Long!!!

If you are working from home, do yourself a favor and get a stand up desk. While you’re at it, get one from these folks. Excellent product, excellent service, no regrets... save one. I should’ve bought this a long time ago.
