Flexispot M3B 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)

Happy Financial Advisor

I've been talking of doing this for months and I finally made it happen. Very happy with the product. Looks great, sturdy, raises and lowers with EASE... now my office is the talk of the office as others come and ask me what I think, where I got it.



Easy transition from sit to stand

Seems well made, durable and very sturdy. Makes the transition very easy and fast without any worries of stability. Raise and lower with coffee on desk with no worries. My only complaint is the height at which the desk remains when in the sitting position. Sits about 6 inches higher than actual desk making sitting and using the very spacious top a little awkward. Chair is at highest position but still not high enough to comfortable view and use the table top when sitting very well.

Thank you for the great feedback, Marvin! I want to quickly explain that the 6' height difference of the top surface actually has a very specific ergonomic purpose. When a monitor sits on your normal desk, most users have to look down to view their screen, which placed strain on your neck and spine. In order to avoid 'forward head tilt,' it's important to have your monitors at eye-level, so your gaze is straight ahead, rather than down. Granted, it can take some getting used to, but over the long haul, it should be better for your neck and spine! Let us know if it gets any more comfortable over time.

Love it. Easy setup and use. I am a tall woman who loves to wear heels - I do not need to take my shoes off while I work at this desk.
