Marti WT HD

Mechanism

The chair is equipped with the LP11 PLUS synchronous movement mechanism. When the selected position is released, the backrest tilts backward in response to the user’s movements. The backrest movement is synchronized with the seat, although the seat’s movement is much less pronounced. The mechanism allows for smooth height adjustment of the seat. It also features seat depth adjustment, which determines the distance between the seat and the backrest. This function reduces the risk of thigh pressure, accommodating users of different heights. The seat depth adjustment range is 5 cm.

Smart Move Technology

Marti chairs are produced using Smart Move technology, developed and implemented in Poland by Grospol. This technology addresses the needs of active users who value intelligent solutions. Its main goal is to enhance sitting comfort and relieve back pressure during long office hours.

Thanks to the unique design of the backrest, it dynamically adapts to the user’s movements. The back remains fully supported, not only during work but also when leaning or making diagonal movements, where the support shifts to the right or left side of the back.

Backrest

The backrest of the Marti WT chair is designed for maximum comfort and ergonomics. Made from 25 kg/m³ cut foam, it provides the right balance of softness and durability, conforming to the user’s back for long-lasting comfort even during extended use. The entire backrest is upholstered in a selected fabric, allowing personalization to match office aesthetics.

Headrest

The HD version features a height-adjustable headrest with an adjustable tilt angle for head support. It offers ergonomic support during work and moments of relaxation.

Lumbar Support

A key element of the backrest is the adjustable lumbar profile, which can be customized in terms of both height and depth. This allows users to precisely adjust the support to the shape of their spine, which is especially important for the lower back that bears the most strain during prolonged sitting.

Armrests

The chair features 3D adjustable armrests that ensure proper positioning of the forearm and hands for desk work. Users can choose between the R10 or R11 models:

R10 Armrests:

• Height adjustment (up/down), allowing forearms to be positioned at a 90-degree angle to the torso, significantly reducing back muscle strain during long hours of sitting. Height adjustment range: 75 mm.
• Forward-backward adjustment (40 mm) to match the armrest length to the forearm.
• Arm pad tilt adjustment of +/- 15 degrees. A soft pad is standard for comfort.

R11 Armrests:

• Height adjustment (up/down) of 80 mm.
• Forward-backward adjustment of 45 mm.
• Arm pad tilt adjustment of +/- 34 degrees.
