The corners of the backrest have been designed to ensure constant support of the back and lumbar. Our products are designed specifically for those in an office chair for extended periods and require intensive-use seating for comfort.

★ 【Premium Materials】 We've incorporated a specially-selected mesh cloth with high tensile strength and breathability properties for the backrest. For mobility, thickened PU rubber castors roll and glide smoothly across the floor and won't scrape or scratch flooring surfaces.
