Lorell LLR99552 Electric Desk Riser with Keyboard Tray

Product Description

The LORELL LLR99552 is an electric sit-stand desk riser with an integrated keyboard tray, designed for ergonomic workstation setup in office and professional environments. A medical-grade electric motor drives smooth, quiet height adjustment from 5.25 inches to 17.125 inches, allowing users to transition between sitting and standing positions without manual effort. The top surface measures 31.5 inches wide by 24.4 inches deep and supports monitors up to 33 pounds. A USB interface is built in for convenient device connectivity. The anti-collision function automatically stops movement when an obstruction is detected, protecting equipment and preventing injury during adjustment.

The LLR99552 is suited for corporate offices, home offices, and medical or clinical workstation environments where quiet, reliable height adjustment is required. The keyboard tray measures 24.25 inches wide by 8.67 inches deep, providing enough space for a full-size keyboard and mouse. This riser sits on top of an existing desk surface, converting a fixed-height workstation into an adjustable sit-stand setup without requiring a full desk replacement. It is appropriate for single-monitor configurations and lightweight multi-display setups within the 33-pound weight limit.

Installation Notes

Installation does not require permanent mounting — the unit sits on top of an existing desk surface and connects to a standard electrical outlet to power the motor. Before operating, confirm the desk surface is level and can support the combined weight of the riser and all equipment placed on it. Verify that the power cord routing does not create a trip hazard and that the USB and power connections are secure before first use. No special tools or licensed trade installation is typically required for standard office deployment.
