1. What makes the Doro S100’s dual lumbar support different from other chairs?
The Doro S100 features a dual dynamic lumbar support system with two independent pieces that adjust to your posture, providing continuous lower back relief. This design targets the muscles under pressure when seated, offering more comprehensive support.
2. How does the S100 compare to the C300 in terms of lumbar support?
The C300 has a single-piece lumbar support inspired by the spine for flexible posture support, while the S100 uses a dual dynamic system for more targeted lower back comfort, making it a better choice for users who prioritize lumbar support.
3. Can I adjust the headrest on the Doro S100 for different activities?
Yes, the integrated headrest can be adjusted up or down. Lower it for more back and shoulder support while working, or raise it for neck support when reclining, offering a personalized comfort experience.
4. What are the reclining options for the Doro S100 versus the C300?
The Doro S100 reclines up to 135°, allowing for more versatile use, from working to relaxing. The C300 offers a recline up to 112°, ideal for shorter breaks or lighter tasks.
5. What is the return and warranty policy for the Doro S100?
You get a 7-day worry-free trial to test the chair in your home. If it doesn’t meet your needs, you can return it. Additionally, the S100 comes with a 3-year warranty to cover any issues that arise over time.
6. Is the seat of the Doro S100 comfortable for long periods of sitting?
Absolutely. The waterfall-shaped seat cushion evenly distributes weight, reducing pressure on your thighs and hips, making it comfortable for long hours of work or gaming.
7. How does the modern design of the S100 compare to the C300’s spine-inspired design?
While the C300 mimics the spine to support various body positions, the S100 takes a more modern approach, with clean lines that target pressure points, creating a sleek look while offering targeted support for prolonged sitting.
