Se7en LX005 – Ergonomic office chair with armrests

The Se7en LX005 is an ergonomic office chair that proves great design and professional comfort can coexist without compromise. Built for modern workspaces, it is aimed at professionals who spend long hours at their desk and refuse to sacrifice aesthetics for well-being. At Wooh, we recommend it for equipping open-plan offices in SMEs as well as for individual executive workstations.

A chair designed for dynamic sitting

Staying still for hours is the enemy of your back. The LX005 features automatic lift technology that adjusts seat height in coordination with the backrest, encouraging an active and natural posture throughout the day. The seat depth is adjustable via a sliding mechanism, adapting the chair to every body type. The tilt can be locked in an active or relaxed position depending on the task at hand.

The height and depth adjustable lumbar support is one of the standout features of this model. It follows the natural curve of the spine and significantly reduces lower back fatigue during long working sessions. Research confirms it: proper lumbar support reduces muscle tension and improves concentration.

4D armrests for total freedom

The 4D armrests on the LX005 adjust in every direction: height, width, depth and rotation. Their soft padding protects elbows and forearms during long typing or mouse sessions. This adaptability is especially valuable in a multitasking environment where you switch between screen, keyboard and phone throughout the day.

Lucia fabric: 11 colours to personalise your workspace

The seat and backrest are upholstered in Lucia 100% polyester fabric, renowned for its exceptional abrasion resistance (100,000 Martindale rubs). This level of durability ensures the chair retains its appearance even in high-use environments such as open-plan offices or co-working spaces.

Black (5800) is available in stock with delivery in 5 to 8 working days. Ten other colours are available to order in approximately 6 weeks: Grey, Dark Blue, Red, Light Green, Yellow, Red-orange, Dark Turquoise, Cobalt Blue, Turquoise and Bordeaux Red. A palette designed to integrate seamlessly into any corporate colour scheme or to add a touch of colour to a neutral workspace.
