      Frequently Asked Questions (FAQ)

      Most office chairs are tailored to smaller body types, as Asia is the biggest market and the leading country of origin. SitOne was made differently to meet wider fit requirements with almost every component being made larger and offering a significantly more range of adjustments.

      Wipe down the chair with a damp cloth to remove dust, dirt, and stains. Avoid using harsh chemicals that can damage the material. Stick to mild soap and water for cleaning. Prolonged exposure to sunlight can cause fading and damage.

      The SitOne chair has a weight limit of 136 kg to ensure optimal performance, durability, and user safety. Exceeding this weight limit may compromise the chair's functionality and longevity.

      We use elastic mesh with small holes that conform to the body shape, providing optimal support in various postures without the need to adjust the back height for comfort. The mesh balances pressure relief and temperature, offering a breathable feel. The seat is made from specially formed high-density foam, which distributes pressure evenly, greatly reducing the strain on your thighs during prolonged sitting sessions.

      The SitOne lumbar pillow effectively supports the natural curve of your lower back. Most chairs on the market have just a plastic lumbar support imitation. SitOne’s lumbar pillow is easy to adjust by going up and down and finding the best position for your back.

      Our limited warranty ensures that the Desktronic chair SitOne is protected against any material or workmanship defects, offering you peace of mind for up to 3 years. Warranties do not cover normal wear and tear or misuse of product.
