Trade terms for professionals and design studios

Specifying a chair for a whole floor usually means choosing one version and living with it. Adell gives five: the bare shell, the shell with a seat cushion carrying an internal ABS support, the fully upholstered shell with a non-removable cover, and two removable options — a seat cushion and a front cover, both available indoor/outdoor.

That range lets one design serve a busy lobby, a quiet consulting room and an outdoor terrace without switching families. The shell is 80% post-industrial recycled polypropylene, the bases are painted steel, sled or plywood with an oak finish, and the intended-use sheet cites EN 16139 for non-domestic seating covering offices, restaurants, banks and bars. Designed by Lievore + Altherr Désile Park in 2020 and handled in the US by La Mercanti, samples first.

FAQ

Why five configurations instead of one?
Because a single building rarely has a single requirement. A lobby that is cleaned nightly, a consulting room where people sit for an hour and a terrace exposed to weather each ask something different from the same chair, and here the difference is a cushion or a cover rather than a different product.
What does non-removable cover mean in practice?
That the fully upholstered version is finished with a cover that is not designed to be taken off. It is stated plainly by the manufacturer, and it is the honest reason to choose one of the removable-cushion options where cleaning has to be frequent.
What is the ABS support for?
It sits inside the seat cushion, under the PU foam, and gives the cushion its structure. It is listed as part of the cushion's construction rather than as an accessory.
Can configurations be mixed on the same floor?
They share the same shell and the same design language, so mixing versions between rooms keeps a project coherent while matching each room's use. Availability of each combination is confirmed on the manufacturer's documentation.
Which versions work outdoors?
The removable seat cushion and the removable front cover are declared in indoor/outdoor versions, and the chair itself is declared for indoor and outdoor use.

How to specify one chair for rooms with different demands

Five steps when a floor needs variety without losing coherence.

List the rooms and their cleaning regime
Cleaning frequency decides upholstery long before comfort does.
Match the configuration to the room
Bare shell, cushion, or fully upholstered: three different answers.
Note what cannot be removed
The upholstered version has a fixed cover; plan for that.
Keep one shell across the project
Coherence comes from the shell, variety from the cushions.
Ask for samples of each
