The S3 is an ergonomic chair focused on everyday comfort and easy use. It’s a great fit for working from home, studying, computer work, and other daily activities. If you want a comfortable chair without a lot of complicated adjustments, the S3 keeps things simple.
The S3 features a high-resilience foam cushion that provides a soft and comfortable feel for everyday work, study, and home use.
If you prefer a softer, more relaxed sitting experience, the S3 is a simple and comfortable choice.
Because more adjustments don’t always mean a better ergonomic chair.
The S3 focuses on keeping things simple and intuitive. Just make the basic adjustments based on your height and sitting position, and you can quickly find a comfortable setup.
The S3 features a lightweight design that makes it easy to move around your home office, bedroom, study, or other spaces. If you often change your workspace, the lighter design makes everyday use more convenient.
Both chairs are designed with everyday ergonomic comfort in mind, but they have different focuses. The S3 prioritizes soft comfort and simple adjustments with a standard foam cushion. The S3 Pro offers more supportive performance with a molded foam cushion, enhanced lumbar support, and a cable-controlled mechanism. Choose the S3 for a softer, more relaxed feel, or the S3 Pro if you want more support and adjustability.
Not at all. The S3 has a simple assembly process and comes with the necessary tools and instructions. It takes about 15–20 minutes to assemble, with no special tools or professional experience required.
