Arper's page hands designers a sentence to work with: the minimal form and soft upholstery of Mixu are “an ideal canvas for material expression”. The canvas is literal. On this fully upholstered chair the seat takes Elmosoft leather or Valencia coated fabric, and the backrest can answer with a different material from the Arper portfolio — or with the client's own. Born in 2021 from the collaboration with Gensler and renewed in the 2025 edition, the design chair extends into counter and bar stools with declared seat heights of 69.5 and 79.5 cm (27.4 and 31.3 in), on four-legged bases in chromed or powder-coated steel or solid oak. Everything holds without glue, so the upholstery can be separated and replaced over the years. La Mercanti paints on this canvas across restaurants, hotel floors, collaborative areas and home offices — one drawing, many fabrics.

FAQ

Which bases can the chair stand on?
Two declared four-legged bases: chromed or powder-coated steel, or solid oak — the wood option carries FSC certification. Same silhouette, two temperatures.
How tall do the two stools sit?
At 69.5 cm (27.4 in) for kitchen counters and at 79.5 cm (31.3 in) for full bar tops — two declared heights, both fully upholstered like the chair.
Can the upholstery be replaced years later?
Yes — because it is applied without glue, the cover can be separated and replaced by technical personnel. A Mixu can change fabric instead of being changed.
Can seat and backrest come in two shades?
Yes, on request and with a declared additional charge: two shades of the same cover, or two different materials altogether — that mix is the idea behind the name.
Is there recycled material in the chair?
Yes: the internal components are declared as partially made of post-industrial recycled plastic, and the whole chair disassembles completely for recycling or reuse.

How to specify Mixu for a hospitality project

One silhouette, three heights, two leg materials and an open fabric palette: five steps to a coherent specification.

Map the seating heights
Dining rooms take the Mixu chair; kitchen counters call the 69.5 cm stool, bar tops the 79.5 cm one. Three heights, one language.
Choose the leg temperature
Chromed or powder-coated steel keeps the scheme technical; solid oak warms it. Decide per room, not per order.
Compose the mix
Pick the seat material — Elmosoft leather or Valencia coated fabric — then let the backrest answer with a second material or shade.
Decide where the client's fabric enters
Customer's own material is declared for the backrest: the house textile can join the project on the most visible rooms.
