Designed specifically for those who spend extensive amount of hours staying seated for work as well as play, the Caliber X2's clean, professional aesthetic with a full array of ergonomic features makes it the perfect addition to your setup. • Ergonomics that Adapt: Caliber R3's ergonomics have been entirely upgraded. Featuring a larger headrest and lumbar support for an improved ergonomic fit for all users, the R3 is suitable for all body types and provides ample support where you need it most. • All-Day Comfort: Caliber R3 features ultra-soft yet dense memory foam that dynamically contours around you for all-day comfort. • Enhanced Seat Base: Caliber R3's seat base has been upgraded from a 9cm thick seat base to a 10.5cm. Increasing the thickness provides enhanced support and durability, ensuring comfort and support for even longer work or play sessions. • Perforated Material: Caliber R3 now uses an all-new, fully blacked-out, synthetic performance PU for perforated patches, matching the same high quality PU leather on other parts of the chair. • Recline The Way You Want: Caliber R3 continues to offer a 180 full-reclining experience. • Reinforced Steel Frame: Caliber R3 continues to use a class-leading steel frame gauge and structural design to deliver a superior experience with durability lasting for many years to come.
