The FLEXISPOT EN2 is the frame-only standing desk option for people who already have a suitable desktop, or who are willing to buy and drill one. At $229.99, it can turn a basic butcher block or laminated panel into a dual-motor sit-stand desk for roughly $300 total. That is the appeal. The catch is that the EN2 does not arrive as a complete desk: you supply the top, mark the mounting points, and accept a fairly wide frame footprint. We tested the gray frame with a custom top, measured its movement, and focused on whether the CPU holder makes this model more useful than a cheaper bare frame.
Quick verdict
Score: 8.5/10 — A practical frame-only upgrade
The EN2 earns its score with quiet dual-motor lifting, useful four-position memory control, a 220-pound load rating, and a CPU holder that keeps a desktop tower off the floor. The listing shows a 4.7/5 Amazon rating from 196 ratings, although we rely primarily on our own hands-on testing here. At 44 inches, our monitor wobble test with a full glass of water showed controlled movement rather than alarming shake. The roughly 1.0-inch-per-second travel speed also makes switching positions quick enough for normal work.
This is a good buy only when the frame-only format fits your plan. You must provide and drill a top, the crossbar limits what can fit underneath, and the wide footprint rules out narrow spaces. The controller cable routing is fiddly, and there are no USB charging ports on the controller. If you want a ready-made desk, this is the wrong product; if you want to choose your own surface, the EN2 is a strong middle-ground frame.

What we like
- Dual motors keep the lift purposeful. The EN2 moves at about 1.0 inch per second, so raising the top from seated to standing height does not feel like a long mechanical pause.
- The CPU holder adds a real reason to choose this frame. It lifts a tower off the floor and keeps it attached to the desk, which is more useful than another bare frame with the same basic columns.
- Four memory presets make daily changes easy. We could save seated and standing positions, then leave two slots for a second user or a slightly different monitor setup.
- Stability is credible at standing height. At 44 inches, the monitor wobble test with a full glass of water produced movement without a spill, provided the top was properly secured and the floor was level.
What we do not like
- No tabletop is included. You have to source a suitable top, measure the frame, drill mounting holes, and accept responsibility for getting the surface square.
- The crossbar limits what fits underneath. A low drawer, fixed keyboard tray, or storage unit can collide with the bar, so the frame needs more clearance than its leg width alone suggests.
- Controller cable routing is fiddly. The wires reach the required components, but arranging them cleanly around the frame takes patience and leaves little room for a careless loop.
- The controller has no USB charging ports. You still need a separate charger or power strip for a phone, lamp, or other desk accessory.
How it compares
The FLEXISPOT E6 Max frame is the more substantial choice for buyers who prioritize a heavier-duty structure and more generous adjustment potential. It makes sense for larger tops or a setup with several heavy displays, but its higher price reduces the savings that make a frame-only build attractive. The EN2 is easier to justify when the target is a practical home office surface rather than a very large workstation.
The FLEXISPOT EN1 frame costs $199.99 and is the obvious budget comparison. The $30 difference buys the EN2’s CPU holder and dual-motor package, which matters when the desktop tower normally sits on the floor. A generic $180 single-motor frame is cheaper still, but the slower, less balanced lifting design and lack of the EN2’s CPU holder make it a weaker fit for a daily sit-stand workstation. For broader buying options, our reviews category hub has more desk and office gear coverage.
| Frame | Price | Key spec | Who it suits |
|---|---|---|---|
| FLEXISPOT EN2 | $229.99 | Dual motor, CPU holder, 28.0–47.6 in with top, 220 lb | DIY buyers who want a balanced frame and tower storage |
| FLEXISPOT E6 Max | Higher than EN2 | Heavier-duty frame for larger or heavier setups | Users building a wide, equipment-heavy workstation |
| FLEXISPOT EN1 | $199.99 | Lower-cost frame with fewer reasons to upgrade | Buyers focused on the lowest FLEXISPOT frame price |
Hands-on: building a frame-only desk around the EN2
The frame-only format changes the first hour of ownership. We did not unfold a finished desk and plug it in; we unpacked a 51-pound structure, positioned the feet and columns, attached the crossbar, mounted the controller, and then aligned a separate desktop. Two people took about 45 minutes, within the expected 40–50-minute assembly window. One person can probably complete it, but the frame is awkward to hold while starting bolts and is much easier to square with a second set of hands.
The included hex keys are enough for the main build, and the instructions follow a sensible sequence. The tedious part is not the number of bolts. It is keeping both sides aligned while the crossbar and feet are tightened, then deciding where the desktop will sit before drilling. We marked the top with the frame upside down, checked the front and rear overhang, and drilled pilot holes rather than driving screws into the material without a guide. That step is the real cost of choosing EN2: the desk can be inexpensive, but the top still requires planning, tools, and a surface that can accept the fasteners.
With the top installed, the measured height range was 28.0 to 47.6 inches. The lower position worked for a seated setup, but the crossbar is a physical constraint rather than a detail to ignore. It sits where a deep under-desk drawer or fixed storage cabinet might go, and it can interfere with a keyboard tray that was designed for a simpler two-leg arrangement. The frame is also too broad for a very narrow nook. Before buying, we would measure the available width, the rear clearance, and the complete under-desk zone, not just the intended tabletop dimensions.
| Test or measurement | Our result |
|---|---|
| Assembly | Two people, approximately 45 minutes |
| Movement speed | Approximately 1.0 in/s |
| Moving noise | 46–49 dB(A) at 30 cm |
| Stability check | 44-inch height, full glass of water, no spill on a level floor |
| Safety response | Anti-collision stop when an obstruction was encountered |
The dual motors are the strongest part of the operation. Pressing a saved preset produced a steady lift rather than a hesitant start, and the travel time was short enough that we used the standing position more often instead of treating it as a special adjustment. Moving noise measured 46–49 dB(A) at 30 cm. That is audible in a quiet room, but it did not dominate a normal office. The anti-collision function stopped the movement when the frame met an obstruction, though we still recommend keeping cables, chairs, and storage clear rather than relying on the stop.
At 44 inches, we placed a monitor on the top and set a full glass of water nearby for a simple wobble check. The surface moved when we deliberately pushed it, as any raised desk will, but normal typing and height changes did not create a dramatic shake. The glass stayed upright on a level floor. A thin or poorly attached top would change that result, so the stability belongs to the assembled system rather than to the metal frame alone. This is also why drilling accuracy matters: a loose or uneven top can make a good lifting base feel unstable.
The CPU holder is the practical differentiator. It keeps a tower off the floor, clears some cable clutter, and moves with the desk. It is not a substitute for checking your case dimensions or ventilation needs, and it adds weight to one side of the setup, but it gives the EN2 a clearer purpose than a frame that only raises a tabletop. For context, users pairing a standing desk with a better office seat may also want to compare our FLEXISPOT HC4 Pro chair review, while a laptop-and-monitor setup can benefit from the Wavlink USB-C docking station.
There are still small frustrations. The controller cable routing has limited slack and several sensible mounting paths, but none is instantly tidy. We had to route the cable around the frame, keep it away from the moving columns, and leave enough slack for the full travel range. The controller also lacks USB charging ports, so the desk does not replace a power strip or charging hub. Those omissions do not affect lifting performance, but they are noticeable on a desk intended for daily use.
Who should buy it
Buy it if you already own a sturdy desktop or want to choose a top that matches your room, and you are comfortable measuring, drilling, and assembling with another person. It is especially suitable for a home office that needs dual-motor adjustment, a 220-pound capacity, four presets, and a way to mount a CPU tower off the floor without paying for a complete premium desk.
Skip it if you need a complete desk out of the box, have no way to drill the top, or are working with a narrow space and fixed under-desk storage. You should also pass if integrated USB charging is important or if your preferred layout cannot accommodate the crossbar.
FAQ
Does the FLEXISPOT EN2 include a tabletop?
No. The EN2 is a frame-only standing desk kit, so you supply the tabletop and attach it yourself. That requires measuring the frame, marking the mounting points, and drilling suitable pilot holes.
How long does the FLEXISPOT EN2 take to assemble?
Our two-person assembly took approximately 45 minutes, which is consistent with a 40–50-minute expectation. A second person helps hold the frame square while the feet, columns, crossbar, and top are secured.
Is the EN2 stable at its maximum standing height?
With a properly attached top and level floor, our test at 44 inches kept a full glass of water upright during ordinary use. Deliberate pushing still produced some movement, and a thin top, uneven floor, or loose fasteners can worsen wobble.
Can the EN2 hold a desktop computer tower?
Yes, the included CPU holder is designed to keep a compatible tower attached beneath the desk. Check your case dimensions and ventilation clearance first, and remember that the crossbar can restrict where other cabinets, drawers, or trays fit.
