Ergomaker 3-Leg Electric Height Adjustable Base

The Ergomaker 3-Leg Electric Height Adjustable Base is an affordably priced sit-stand solution which employs three synchronized motors to provide smooth, quiet lifting of up to 330 pounds from 23.5" - 49.5". The motors feature a soft start feature that eliminates potentially jarring movement and a 6-button programmable control featuring 4 preset one-touch height options. The primary frame is adjustable in width from 43" - 73.6" and is capable of accepting tops 20" - 36" in depth. The modular 3rd leg mounts independently of the primary frame, offering a degree of customization for configuration. The wide range of features, universal application, and a comprehensive 5-year warranty make the Ergomaker 3-Leg Electric Height Adjustable Base a good selection for many sit-stand corner applications. Assembly is simple and can generally be accomplished in under an hour. Note: This frame does not work with 3-piece corner desks. As well, the primary frame must be mounted to bridge the joint between the primary and secondary tops. See the Usage Tips for more details regarding top selection.

The "T-base" design centers the 3-stage lifting legs over the base, providing a level of stability that approaches that of other higher priced solutions, even at the highest of elevations. Users are able to store up to four preferred one-touch height settings or can manually adjust the desk height with the up/down buttons. With a height adjustment speed of 1.5" per second little time is spent waiting for adjustments to be completed. For safety, the base features a "stop and reverse" built-in Anti-Collision protection in the event that the table collides with a fixed object.

NOTE: A variety of table top options can be mounted to this frame including custom-made tops or reusing pre-existing tops.

For simple rectangular desks the basic 2-Leg version of the Ergomaker Electric Height Adjustable Base offers the same width and height adjustments with a 220 lb lifting capacity.

• Infinitely Adjustable, Reproducible Effortless Height Adjustment: The Ergomaker 3-Leg Electric Height Adjustable Base offers infinite adjustment of height from 23.5" to 49.5", with a digital LED indicator allowing users to quickly and precisely adjust the height of the worksurface to the optimal height for the desired workstation configuration (sitting, standing, or anything in-between). Four optional programmable presets can also be used to ensure consistent height settings.
• Programmable 6-Button Control: The convenient control panel offers 4 preset height options as well as manual Up/Down buttons for fine tuning height preferences. A clear digital readout displays current height setting and programming details. Once programmed the frame can be adjusted to any of the 4 presets with just a single touch, letting the desk adjust independently as you perform other tasks.
  Note: Programmable presets should always be fine tuned to account for the time of day (i.e. by afternoon users are no longer standing as upright or tall as in the morning), height of shoes, etc.
• Clean Styling: Ergomaker bases offer simplicity of design. The open design and clean straight lines mean the bases will fit in any environment. Ergomaker sit-stand bases are available in either Black or Silver finish.
• Width Adjustable: The Ergomaker Electric Height Adjustable Base primary section can adjust from 43" up 73.6" in width, accommodating tops from 44" to 96" in width. Positioning of the modular third leg is limited only by the length of the cables and the strength of the top. Caution is advised to not create an open span width beyond what your particular top is able to accommodate without bowing.
• Centered Legs for Stability: The electric central leg supports offer optimum balance and when combined with the third leg of the frame create a stable 3-point base for corner and L-shaped worksurfaces.
• Anti-Collsion Safety Feature: If the table top meets a fixed obstacle while moving in either an upward or downward direction, the desk frame will stop and reverse slightly to eliminate any pressure against the obstacle.
• "Soft Start" Feature: Ergomaker Electric Height Adjustable Bases have a soft-start feature which eliminates the potential for abrupt starts or stops.
• Triple Nesting Columns: The nested telescoping legs provide a full 25" of height adjustment with minimal effect on stability even when at maximum height.
• Adjustable Levelling Feet: The base includes adjustable feet which can be adjusted 0.4" (1 cm) to ensure the base is level and to compensate for floor unevenness.
• Overload and Overheat Protection: Ergomaker Height Adjustable frames include both Overload and Overheat protection circuits designed to protect the leg motors from unintentional overuse or overloading.
• Environmentally Conscious: Standby power consumption is just 0.1 watts which translates to under 0.8 Kw consumption per year based on 24 hour standby. With actual consumption of 300 W while being adjusted - allowing for 4 full height adjustments per hour, 10 hours a day, 5 days a week and 52 weeks of the year - the total energy consumption for a year should come to about 15 kWh. Many users will probably make shorter and/or fewer adjustments which will reduce the actual energy consumption accordingly.
• Recyclable Packaging: Ergomaker Height Adjustable frames are shipped in sturdy but fully recyclable packing materials.

• Tools Required: Allen Wrenches (included). Installation of top and control panel will require a Phillips screwdriver.
  Note: Always ensure that screws used for mounting the top are of appropriate length.

• When assembling your frame and installing the top check to ensure that the length of screws being used to secure the top are of appropriate length. You don't want to find that your new desk has screws poking through the surface.
• Desk top thickness and construction materials determine the maximum safe distance for an unsupported span or for top overhang. Care should be taken to ensure that heavy items placed on the desk top are positioned in such a way that their weight is positioned over or in reasonably close proximity to a supporting leg or frame. Placing heavier items in the middle of an unsupported span can, over time, lead to bowing. Tops should be at least 0.75" thick, preferably thicker. Overall strength and resistance to bowing generally increases with both thickness of the top as well as in relation to the materials from which it is constructed. With thinner tops the width of unsupported spans should probably be no wider than 24". Remember that the 2-leg portion of the frame must bridge the joint between primary and secondary tops.
• Don't stand for too long. Certainly in the initial period, limit your standing to 15 to 20 minutes per session unless you are already used to extended standing.
• Switch! Set a notification on your computer or phone to remind you to switch between sitting and standing on a regular basis. Doing so will help you develop the habit of switching throughout the day.
• Don't just stand there! Try to consciously use your leg and core muscles as you stand. Allow your body to shift and especially make a point of moving and flexing your leg muscles. By doing so, you encourage healthy blood flow in the lower legs. This can help you avoid the problems that can arise when people stand for a long time without moving.
• Be sure to consider your height as you position your desk. Be aware that the height of your heels and even the time of day will affect your standing height. (Everyone is a tiny fraction shorter at the end of the day than they are in the morning.) Ensure that you adjust the desk accordingly to achieve a neutral posture.
• Try to avoid high heels if you plan to stand while you work. These will tire your feet and increase the risk of damage to the structures of your feet and lower leg.
• Consider an anti-fatigue mat. Many users find that standing is actually tiring, especially so with the hard surfaced floors on which most people work. The shortnap carpet that is common in many office or retail environments does little to mitigate the rigidity of the concrete it usually covers. A good mat can leave you much less fatigued at the end of the day as it encourages flexing of the feet and lower leg muscles. If you wish to regularly switch between standing and sitting you will want a mat which can be easily moved when transitioning between the two positions. For available options, visit our Anti-Fatigue Mats category.
• Try leaning. If you discover that you like working in an upright position but find that extended standing fatigues your body you may wish to consider one of the many seating options designed for working at elevated desks. These reduce the load on your feet by letting you transfer the majority of your weight to the seat. The 'almost upright' stance provides most of the mobility and range of movement that standing offers, while reducing the risk of fatigue. The leaning position also helps you transition effortlessly to a standing position. For available options, visit our Seating for Sit-Stand Workstations category.
