You have finally decided to make the switch. After years of hearing about the benefits of alternating between sitting and standing throughout the workday, you are ready to invest in a height-adjustable desk. But then you start looking at the options, and suddenly things feel more complicated than expected.
FlexiSpot offers several standing desk models, and at first glance, the EG1, EF1, and E1 Pro can look remarkably similar. They all lift smoothly. They all support a range of user heights. They all promise to help you break free from the sedentary habits that leave your back aching and your energy flagging by mid-afternoon.
But beneath the surface, these three desks have meaningful differences that matter depending on your workspace, your equipment, and your priorities. This guide will break down exactly what sets them apart, so you can choose the one that fits your needs.
At a Glance: How the Three Models Compare
Before diving into the details, here is a quick overview of how the EG1, EF1, and E1 Pro stack up against each other.
| Specification | EG1 | EF1 | E1 Pro |
| Motor | Single | Single | Dual |
| Leg Segment Range | 710–1210 mm | 710–1210 mm | 700–1190 mm |
| Load Capacity | 70 kg | 70 kg | 100 kg |
| Speed | 25 mm/s | 25 mm/s | 25 mm/s |
| Noise | <50dB | <50dB | <50dB |
| Anti-Collision | ✗ | ✓ | ✓ |
| Memory Presets | ✗ | ✓ | ✓ |
| Warranty | 3 years | 3 years | 3 years |
| Desktop Length | 1000–1600 mm | 1000–1600 mm | 1200–1800 mm |
| Desktop Width | 500–800 mm | 500–800 mm | 600–800 mm |
As the table shows, all three models share the same lifting speed and noise level. The differences emerge in motor configuration, smart features, load capacity, and desktop compatibility.
Motor Performance: Single vs Dual Motor
The motor is the heart of any standing desk. It determines how smoothly the desk lifts, how much weight it can carry, and how reliably it performs over years of daily use.
EG1 and EF1 – Single Motor Design
Both the EG1 and EF1 use a single motor system. In this configuration, one motor drives both legs via a synchronisation rod, ensuring the desk rises and lowers evenly. For most users, this design works perfectly well. It delivers smooth, reliable height adjustment at a cost-effective price point.
The single motor provides a 70 kg weight capacity, which comfortably supports a typical office setup: a desktop, one or two monitors, a laptop, keyboard, mouse, and assorted desk accessories. A lifting speed of 25 mm per second means that transitioning from sitting to standing takes about 10 seconds—quick enough to encourage regular position changes throughout the day.
E1 Pro – Dual Motor Advantage
The E1 Pro takes a different approach. Instead of a single motor driving both legs, it features a dual-motor system with an independent motor in each leg. This configuration offers several meaningful advantages. --altImgStart--{"link":"https://s3.springbeetle.top/prod-common-bucket/commodity/item/UKaswede_20260330_Tl7W76bp.png","alt":"Height Adjustable Desk with Dual-Motor Drive (E1 Series)"}--altImgEnd--

First, the lifting motion is even smoother and more balanced. Because each leg has its own motor, the desk rises with greater precision and stability. Second, the dual motor system supports a higher weight capacity of 100 kg. This makes the E1 Pro the better choice for heavier setups: large desktop surfaces, multiple monitors, a full-tower PC, or any combination of equipment that approaches the 70 kg limit of single-motor desks.
Despite the additional power, the E1 Pro matches the EG1 and EF1 with a 25 mm per second lifting speed and sub-50dB noise level. You get more capability without sacrificing speed or quiet operation.
Smart Features: Memory Presets and Anti-Collision
Modern standing desks offer more than just up-and-down buttons. Smart features can make the difference between a desk you use consistently and one that becomes an occasional indulgence.
EG1 – Simple and Reliable
The EG1 keeps things straightforward. It includes basic lift control: press up to raise the desk, press down to lower it. There are no memory presets and no anti-collision technology.
For users who set their standing height once and rarely change it, or who prefer a no-fuss approach, the EG1 does exactly what it needs to do. It is the entry point into the standing desk world, offering reliable performance without added complexity.
EF1 – Enhanced Convenience
The EF1 adds two features that significantly improve the daily experience. First, memory presets allow you to save your preferred sitting and standing heights. With a single press, the desk moves to your saved position—no holding down buttons, no fine-tuning to get back to the exact height you prefer.
Second, the EF1 includes anti-collision technology. If the desk encounters an obstacle while lowering, it automatically stops and reverses direction. This provides peace of mind, especially in homes with children or pets who might leave objects in unexpected places.
The EF1 strikes a compelling balance: the simplicity of a single motor, the convenience of memory presets, and the safety of anti-collision.
E1 Pro – Full Feature Set
The E1 Pro includes everything found on the EF1, memory presets, and anti-collision, and adds a dual-motor system. The result is the most polished user experience across the three models. Memory presets respond instantly. Anti-collision works seamlessly. And the dual motor delivers the smoothest motion in the lineup.
For users who want the best of everything, the E1 Pro delivers. --altImgStart--{"link":"https://s3.springbeetle.top/prod-common-bucket/commodity/item/Screenshot%202026-03-30%20160147UK_20260330_cSBw2kCB.png","alt":"Height Adjustable Desk with Dual-Motor Drive (E1 Series)"}--altImgEnd--
Build and Stability: Crossbeam Design
Stability matters more than many buyers realise. A desk that wobbles at standing height, especially when typing or leaning on the surface, can undermine the entire standing desk experience.
The EG1 and EF1 feature a single crossbeam design. This provides adequate stability for most setups, particularly when paired with desktops within the recommended size range. For standard office configurations, the single crossbeam keeps the desk steady during use.
The E1 Pro upgrades to a dual crossbeam design. Two crossbeams spread the weight more evenly across the frame, reducing the subtle wobble that can occur at taller heights. This design difference matters most for users with larger desktops, heavier equipment, or those who simply want the most stable foundation possible.
Desktop Compatibility and Workspace Considerations
The desktop you choose or already own must match the frame you select. Each model supports different desktop size ranges.
The EG1 and EF1 accommodate desktops with lengths between 1000 and 1600 millimetres and widths between 500 and 800 millimetres. This covers most standard office desktops and many home office setups.
The E1 Pro supports larger desktops, with lengths from 1200 to 1800 millimetres and widths from 600 to 800 millimetres. The combination of dual-motor power and dual-crossbeam stability allows the E1 Pro to handle a larger surface area without compromising performance.
If you already have a desktop you plan to use, check its dimensions against these ranges. If you are buying a desktop alongside the frame, consider how much surface space you truly need. The E1 Pro offers the most flexibility for larger workspaces. --altImgStart--{"link":"https://s3.springbeetle.eu/prod-eu-s3/trantor/attachments/UK/E1Pro-20250606-img7-1.png","alt":"Height Adjustable Desk with Dual-Motor Drive (E1 Series)"}--altImgEnd--

- Budget is your primary consideration
Choose the EF1 if:
- You want memory presets for effortless height switching
- You value the safety of anti-collision technology
- You want a balanced mix of features and value

Choose the E1 Pro if:
- You have a heavy setup (multiple monitors, a large desktop, heavy equipment)
- You prioritise the smoothest and most balanced height adjustment
- You want the most stable frame with dual crossbeam construction
- You plan to use a larger desktop (up to 1800 mm length)
- You want the best overall performance and are willing to invest accordingly
