The EM7 is a Great Value

The Flexispot AlcoveRiser Em7 Motorized Standing Desk Converter offers all the benefits of an electric standing desk while still using your existing furniture. The laptop cutout in the desktop is a great feature, as well as the USB input on the control to charge your phone or tablet. It is easy to assemble and well-made, and although it has minor vertical stability issues, its pros dramatically outweigh its cons.

Its' 44 lb weight capacity is 30% higher than the average converter. At $299, it is much less expensive than a full-electric standing desk and not much more expensive than many manual standing desk converters. The 5-year warranty on the frame and the desktop and the 3-year warranty on the lifting mechanism is above average. It offers good value and delivers on expectations.

Delivery and Above-Average Warranty

As with all Flexispot standing desk converters, taking delivery is simple. Standing desk converters can be shipped cost-effectively with free Prime shipping on Amazon or free shipping through the company’s site. This can be one of the gotchas with ordering standing desks. Many standing desk solutions are excessively heavy or large, and shipping can significantly add to the total purchase cost. We find ourselves saying this a lot, but this is one of the benefits of choosing a standing desk converter over a full stand-alone standing desk.

Flexispot offers a limited warranty on all its products, primarily protecting buyers against craftsmanship issues or defects. According to the Flexispot warranty page, standing desk converters purchased on October 5, 2016, or after are covered with a 5-year warranty on the frame and desktop and 3 years on the lifting mechanism. The site does a great job explaining what the warranty covers, how issues are handled if there is a problem, and how you can file a claim with them.

Simple 2-Step Assembly

Unboxing and assembling the Flexispot Motorized Standing Desk Converter is a headache-free process. There are only two steps in the assembly, and neither requires tools. The first step is to attach the keyboard tray. Like other Flexispot converters, the keyboard tray slides into brackets on the desk and is secured by flipping levers. This is nice, not only because it is simple, but if you ever needed to move or store the desk, you could have the keyboard tray removed in seconds.

The final step in assembly is to attach the motor cable to the transformer. As with most electric standing desk motors, they use a lower voltage than what your typical wall outlet supplies. One benefit of this two-stage power cord is you often get a very long cable, In this case, 10'.


Great Ergonomics

The Flexispot Motorized Standing Desk Converter has a lot of nice ergonomic touches we like to see in a converter. The oversized keyboard tray, a trend sweeping across the converter market, is nearly the width of the entire desk. This allows you to use a large keyboard with a number pad, a large mouse pad and still have plenty of room to use for your phone, a drink, or any other loose items. The tray is so large it is an extension of the desktop area. The converter also features beveled edges, which are easy on your wrists.

The cutout for the laptop is a nice touch, as well as the USB charging port on the controls.



We like the simple design but would like to see more tabletop options or colors. Right now on Amazon.com, there's black or rustic wood, and on FlexSipot.com there's only black. Many office products tend to be a generic black or white color and texture like this.

Easy Setup and Installation

Setting up the Flexispot Motorized Standing Desk Converter is simple and self-explanatory but we’ve done this a bunch and have some tips to share:

  • Make sure you use the included cable wrap. Not only does this help organize your cables, it helps your cables slide along the edge of your existing desk as you raise or lower the converter.
  • Be careful how you route keyboard or mouse cables, especially near the mechanicals and moving parts. The fact that this is a motorized unit can make it easy to pinch or even sever a keyboard or mouse cord.
  • Make sure you have enough slack in the cords for your monitor and laptop, 12" to 14" should be plenty.

Great Operation and Average Stability

The operation is really where the Flexispot Motorized Standing Desk Converter shines. It has an impressive weight capacity of 44 lbs, the highest of any converter we've reviewed (except for our top Luxury pick, the UPLIFT E7, which holds an incredible 110 lbs). Most options are around 25 to 35 lbs, which we consider the bare minimum for most single monitor/laptop or dual monitor setups, especially when adding steel monitor arms. The desk rises and lowers with ease using the two-button control unit. However, the control unit doesn’t have options for memorizing your height settings, a feature we’ve come to love with most electric standing desks. To be fair, the only converter we've seen with presets is the UPLIFT E7.

The motors seem quite strong as there was no change in speed or motor sound between the empty desk loaded with 30 lbs. The motor noise is present but hardly bothersome. It’s quieter than most of the electric standing desks we’ve reviewed.

Stability is good side to side and forwards and back; however, we did notice some vertical give when the unit was raised. This give was about a ½” so if you’re a heavy typer or tend to put weight on the keyboard tray with your wrists, you may notice it more than others. This is a very minor criticism of the stability when raised.

When lowered, the stability is rock solid all around. We like how the keyboard tray rests directly on the desktop. This makes typing when the unit is lowered feel like your keyboard is directly on the desk. Many converters don’t quite lower all the way to the desktop, resulting in some stability issues when lowered. Overall, this converter is about average in stability when raised and excellent in stability when lowered.


Sizes and Options

Currently, the Flexispot Motorized Standing Desk Converter is available in a 36”, 40", and 42" on Amazon.com, and 36" and 40" on FlexiSpot.com. These are adequate sizes for dual monitors, a monitor and laptop stand or even a very large single monitor or iMac.

Colors, as mentioned before, are currently limited to a black textured desktop and black frame on FLexiSPot.com and black or rustic wood on Amazon.com.

Flexispot does offer a variety of great accessories on their site including monitor arms, under-desk bike (which we’ve reviewed), standing mats, and ergonomic seat cushions.


It represents excellent value for someone that wants to keep their existing furniture and enjoy the benefits of standing with an electric converter.
