Design & Build

The SIHOO B300 has a clean, contemporary profile that suits modern offices and refined home workspaces. Its black mesh upholstery is paired with a dark PP+ frame and a sleek silver-toned five-star base, creating a professional black-and-grey finish that works easily with most desks and interiors. The high-back silhouette, broad mesh headrest and shaped lumbar section give the chair a purposeful ergonomic appearance, while the contoured mesh seat and neatly integrated controls keep the overall design streamlined. It is not a folding chair; it is a full-featured rotating office chair made for a dedicated workstation.

Ideal For

This adjustable mesh chair is an excellent choice for remote workers, office teams, managers, designers, programmers, students and anyone building a more comfortable desk setup. Use it in a home office, corporate office building, studio, workshop or shared workspace where versatile support and a smart presentation matter. The generous adjustment options also make it particularly useful where more than one person may use the same workstation.
