Redmian HE Series Electric Height-Adjustable Desk Converter: Smart Lifting Technology Powers Healthier Office Work
Dongguan Yihong Health Technology Co., Ltd., an emerging player in China's healthy-office market, has launched its HE Series electric height-adjustable desk converters under its flagship brand, Kcourorouge. Built around the design philosophy of "Smart Lifting Technology Powers Healthier Office Work," the new lineup leverages years of ergonomic research to deliver a full-scenario, full-height sit-stand solution for employees who spend long hours seated. The series is engineered to overcome the common limitations of traditional height-adjustable desks—poor adaptability, noisy operation and fragmented functionality—and to set a new benchmark for healthy-office standards.
According to data from Science Popularization China, when a person sits in a forward-leaning posture for extended periods, the lumbar spine bears 2.7 times the pressure it would sustain while standing. Prolonged sitting in a fixed position is strongly associated with lumbar and cervical strain, abdominal fat accumulation and other health issues, whereas standing work can effectively relieve spinal pressure and increase calorie burn. The Redmian HE Series requires no replacement of existing office desks or chairs and no complex installation. Users can switch seamlessly between sitting and standing postures and quickly create a healthier office environment at relatively low cost.
The HE Series lineup is clearly structured, offering two color options and five distinct models and sizes to fit a range of existing desk dimensions and meet the varied demands of personalized use scenarios. The flagship HE-91 features a 91 × 52 cm tabletop that easily accommodates dual monitors or a laptop paired with an external screen. Its specially designed 40 cm extra-wide keyboard tray lets users rest their forearms on the tray while typing, effectively reducing the risk of occupational injuries such as tendinitis and shoulder periarthritis.
The entire series is constructed with eco-friendly panels and cold-rolled steel, and is available in two finishes: Wise White (HE-91W) and Premium Grey (HE-91G). Its lifting range spans 130 mm to 500 mm, accommodating users from 140 cm to 195 cm tall for comfortable sit-stand alternation. The ultra-quiet motor operates at below 40 decibels and has passed more than 30,000 load-bearing fatigue cycles as well as the BIFMA X5.5 structural stability test. The tabletop is pre-drilled with mounting holes for monitor arms and fitted with storage hooks. It also includes built-in wireless charging, dual USB ports and a Type-C fast-charging port compatible with both iOS and Android devices, addressing concerns about insufficient battery life for office devices.
The HE-118 series features an extra-large tabletop, offered in Premium Grey (HE-118G) and Wise White (HE-118W), with a tabletop dimension of 60 × 118 cm and a lifting range of 140 mm to 540 mm. Its motor supports a maximum load of 35 kg, securely holding multiple monitors, keyboards, documents, cups and other daily office items. The HE-118C variant features a unique triangular tabletop measuring 73 × 118 cm, specially tailored for corner workstations to suit more personalized scenarios and maximize the use of irregular office space. Smaller models, including the HE-61 and HE-71, are also available for more compact and diversified workstation layouts.
For its core lifting technology, all Redmian HE units are equipped with proprietary motors featuring fourth-generation motor technology and an upgraded independent horizontal-correction function. This design increases lifting speed by 26.6% and ensures smoother, more stable lifting. Combined with a vertical X-type stable structure, the product supports precise height locking at any position, stepless height adjustment, automatic horizontal correction and one-touch operation. It is easy to control even for users with limited physical strength, ensuring a user-friendly experience.
For noise reduction, the R&D team applied a three-tier noise-optimization process to the motor, bringing operating noise down to as low as 36 decibels. This is far below the roughly 60 decibels of daily conversation and well under the 40 decibels of a soft whisper, creating a quiet environment that will not disrupt concentration or disturb nearby colleagues. The series has obtained a number of national patents in China, ensuring lifting stability and a distinctive user experience through structural design.
Human-centered details, safety and comfort are all fully considered. At its lowest initial height, the keyboard tray rests flush against the original desk surface, eliminating the uncomfortable height differential at the edge that can cause wrist soreness. The tray also elevates the screen to help users maintain a natural, upright viewing posture, effectively reducing cervical spine pressure. The 40 cm wide keyboard tray not only improves typing comfort for users with longer forearms but also expands the range of motion for the mouse, further enhancing office efficiency. Most importantly, it allows users to support their forearms on the tray while typing, helping prevent tendinitis, shoulder periarthritis and other common occupational disorders.
For safety and universal adaptability, all tabletop edges are finished with rounded corners to prevent accidental bumps and scratches. The inner curved structure fits the natural contours of the body, reducing uncomfortable pressure against the abdomen and making the product suitable for users of different body shapes. Pre-drilled mounting holes for monitor arms are provided on the tabletop, allowing users to install a third-party monitor arm for free adjustment of height, tilt and screen orientation, helping to further relieve neck fatigue. Redmian also offers a usage tip: from an ergonomic safety perspective, users should position the desk converter so that the front edge of the keyboard tray extends 8 to 15 cm beyond the edge of the original desk, achieving a safer position and a more comfortable working posture. All electrical components comply with market-access standards in the countries and regions where the products are sold and are fully compatible with local conventional power-supply conditions.
Driven by both product excellence and brand credibility, Redmian is strengthening its foundation in the healthy-office market. As the flagship product launched by Dongguan Yihong Health Technology Co., Ltd. in the healthy-office track, the Redmian HE Series delivers a cost-effective solution to the health risks of prolonged sitting for domestic office workers, backed by solid technical capabilities and deep insight into user needs.
Beyond its strong product performance, the brand has also earned official recognition for its credibility. Kcourorouge, the brand under Yihong Health Technology, recently received three honors in 2026: "Guangdong 3·15 Trustworthy Consumer Brand," "Top 30 High-Quality Enterprise Directory of Guangdong 3·15" and "Quality Demonstration Unit," and was named a "Guangdong 3·15 Anti-Counterfeiting Co-Construction Unit." These recognitions reflect the company's outstanding performance in quality control and consumer-rights protection.
Huang Jianming, founder of Redmian, said the honors are both recognition and motivation for the brand. In the future, Redmian will continue to focus on the ergonomic office field and launch more practical, aesthetically pleasing healthy-office products.
