ICF opens the Kuna presentation on a contradiction and does not try to resolve it: the warmth and tradition of leather against a clean, modern aluminium line. Most executive chairs pick a side. This one keeps both materials visible and lets the eye move between them.
It works because neither is treated as decoration. The leather is not a cover laid over foam: a panel is wrapped around the padded frame and left suspended, so it takes the body's weight as a stretched surface. The aluminium is not hidden either — the load-bearing elements are exposed, cast rather than bent, and finished polished or chrome to match the base and the closed armrests.
The consequence is a chair with only two materials in it, which is unusually few for the category and the reason it settles into a panelled boardroom and a glass-walled office equally well. Leather comes in four colours: black, white, dark brown and Bulgarian red. La Mercanti specifies Kuna Chair across the UK with samples in hand and the finish schedule agreed before anything is ordered.
Collection: Kuna Chair
Manufacturer: ICF Office — ICF S.p.A., Vignate (Milan), Italy
Frame: steel tubular sections forming a rigid construction that holds its shape under considerable stress; exposed load-bearing elements in die-cast aluminium, finish 47 polished or 55 chrome; three back heights
Back and seat: leather panel wrapped around the padded load-bearing structure over variable-density polyurethane foam sheets; the panel remains suspended, distributing body weight evenly
Armrests: closed form in die-cast aluminium, finish matched to the frame; optional leather covering; can be omitted without compromising the integrity of the chair
Leather: category S full-grain cowhide, 2.7–3 mm (0.11–0.12 in) thick, 100% vegetable re-tanned; four colours: S01 black, S02 white, S03 dark brown, S05 Bulgarian red
Models: low back KUNA.708 (fixed height with auto-return mechanism, four-star base on glides), .709 (height-adjustable, five-star base on castors) and .717T (with tilt mechanism); medium back .715, .718 and .719T; with headrest .710, .713 and .714T; hide-covered armrests on request on every model
Dimensions: width 60 cm (23.6 in) and depth 48 cm (18.9 in) across all nine models; overall height from 83 to 133 cm (32.7 to 52.4 in) depending on model and back height; seat height 48 cm (18.9 in) on fixed-height models, 43-54 cm (16.9-21.3 in) on adjustable models, 44-56 cm (17.3-22 in) on tilt models
Height adjustment: pneumatic unit with lever, maximum travel 12 cm (4.7 in); gas lift compliant with EN 16955:2017
Auto-return mechanism: not height-adjustable; the swivel seat turns freely and returns automatically to the front-facing position; standard on four-star base models
Tilt mechanism: seat pivot point set well forward of the gas column axis to reduce pressure on the lower limbs while tilting; up to 13 degrees of movement; side knob adjusts balance spring tension to the user's weight and sitting style; lever controls combine seat height, locking and unlocking the tilt in four positions, and the safety lock
Base: four or five-star in die-cast aluminium, chrome or polished to match the frame; with castors or glides
Castors and glides: castors in black plastic, 50 mm (2 in) diameter, soft central element for use on any floor, safety brake compliant with EN 12529:2001, chromed zamak top cover; hard-tread castors available on request; glides in black nylon, 37 mm (1.5 in) diameter, with a soft rubber central element
Weight and materials: approx. 12.4 kg (27 lb) (technical sheet), 14–20 kg (31–44 lb) depending on model (price list); aluminium 48 per cent, metal 28 per cent, miscellaneous 24 per cent; approx. 77 per cent recyclable when the components are fully and correctly separated; every component can be dismantled for repair, reuse and recycling; formaldehyde-free and free of hexavalent chromium; designed according to eco-design guidelines. Data refer to model KUNA.708 and may vary by model, structural materials and finishes
Certification: EN 16139:2013 level 1, declaration of conformity no. 11108 of 13 January 2014 on KUNA 715 following tests to EN 16139, EN 1728 and EN 1335; ANSI-BIFMA X5.1, CATAS test report on KUNA MID BACK 708
Care: leather is a natural product and the wrinkles and scars on the grain attest to its origin and quality rather than being defects; avoid direct light so the leather does not dry out or harden. Aluminium: soft cloth with water and neutral soap, never solvents, thinners, alcohol, abrasive or chemical cleaners or polishing sprays; chrome aluminium keeps its brightness over time, polished aluminium undergoes a natural oxidation process. Only trained personnel may replace or repair the gas lift
Spare parts and accessories: set of five castors with chrome cap, set of four or five black glides
