Once locked, it stays incredibly firmly in place, securing rock-solid support for up to 260lbs whether gaming, working, or relaxing.
Leather or linen fabric - which should I choose?
For design schemes, leather stands out with its modern exteriors, sleek lines, and elegant appeal, while soft and cozy linen fabric adds warmth and comfort to your living space. In terms of performance, leather excels with its durability, waterproofing, stain resistance, and ease of cleaning. Fabric options like linen offer a softer, more breathable experience. Each material offers unique benefits, so choose based on your specific needs and preferences for comfort, style, and practicality.
