Marti WT

Mechanism

The chair is equipped with a synchronous LP11 PLUS movement mechanism. Once the selected position is released, the backrest tilts backward in response to the user’s movements. The backrest movement is synchronized with the seat movement, although the seat movement is less pronounced. The mechanism allows for smooth seat height adjustment and also offers seat depth adjustment, which determines the distance between the seat and the backrest. This feature helps to reduce the risk of thigh pressure, making the chair suitable for users of different heights. The seat depth adjustment range is 5 cm.

Smart Move Technology

Marti chairs are produced using technology developed and implemented in Poland by Grospol – Smart Move. This technology responds to the needs of active users who value intelligent solutions. Its primary goal is to improve sitting ergonomics and reduce back strain during long office work.

Thanks to the unique backrest design, it dynamically adjusts to the user’s movements in the chair. The back is supported along its entire height, both during work and while reclining or making lateral movements, where the support weight is distributed on the right or left side of the back.

Backrest

The backrest of the Marti WT chair is designed with maximum comfort and ergonomics in mind. Made from cut foam with a density of 25 kg/m³, it offers the right softness while maintaining durability, allowing it to perfectly adapt to the user’s back and provide long-lasting comfort even during extended periods of use. The entire backrest is upholstered in a chosen fabric, allowing personalization of the chair to match the office decor.

Lumbar Support

A key feature of the backrest is the adjustable lumbar support, which can be customized for both height and depth. This gives the user the ability to precisely adjust the support to the shape of their spine, which is particularly important for the lower back, often subjected to the most strain during long periods of sitting.

Armrests

The chair is equipped with 3D adjustable armrests that ensure proper positioning of the forearm and hands for desk work. Two armrest models are available: R10 or R11.

• R10 Armrests:

  • Height adjustment (up-down): Allows the armrest to be set at a height where the forearm forms a 90-degree angle with the torso, which significantly reduces back muscle strain during long hours of sitting. The height adjustment range is 75 mm.
  • Depth adjustment (front-back): Adjustable within 40 mm, allowing the armrest to be tailored to the forearm length.
  • Angle adjustment of the pad: +/- 15 degrees, with a soft pad standard for comfortable use.

• R11 Armrests:

  • Height adjustment: 80 mm range.
  • Depth adjustment: 45 mm range.
  • Pad angle adjustment: +/- 34 degrees.

Seat

The seat is profiled and made of durable, deformation-resistant foam with a density of 25 kg/m³. It is upholstered in a selected fabric from Grospol’s wide range of options.

Base

The lightweight, mobile base is available in either white or polished aluminum. It comes with 60 mm diameter wheels, which are safe for parquet and laminate floors and work well on carpets too.

Warranty

The product is covered by a 3-year door-to-door warranty, ensuring full convenience for the user.
