Grey polypropylene, a bar behind the mesh: the lumbar support of Assia EV leaves the factory like that. Vaghi lets it be padded on request, with a cushion in grey flame-retardant fabric, height-adjustable like the bar beneath it and ordered as a line of its own, for anyone who wants the support softer. Among the height-adjustable task chairs of the programme it is a quiet option, one line after the chair code, felt rather than seen.
The chair under the cushion was drawn by Vaghi R&D and reads like a short list: a medium backrest in mesh that rises and reclines, an upholstered seat that swivels and lifts, the grey bar with its position indicator. The synchronised mechanism is listed twice, as a weight-activated version and as one with tension adjustment, and an anti-return safety device is on each. Three weaves dress the back, one in polyester and two flame-retardant, which is what places Assia EV among mesh-backed office seating.
By what sits on the frame there are three ways to have it: with headrest and armrests, with armrests alone, or as a plain chair with neither; the white series and the black series run through all three, plastics, arms and castors included, and the cushion goes on any of them. La Mercanti puts the chair with the pad and the chair without it next to each other, because the choice is felt with the back, not read in a code.

Vaghi prints a gross weight and a packed volume for every build. The armchair with headrest and armrests ships at 21 kg (46.3 lb) in 0.55 m³; the armchair with armrests at 18.5 kg in 0.5 m³; the chair without armrests at 17.5 kg, again 0.5 m³. They are the figures a delivery is planned on, build by build, and the ones to put on the transport note before a floor of chairs is ordered. Three figures for three builds: what separates the heaviest from the lightest is the headrest and the pair of armrests.
The R1. Vaghi declares Assia EV approved in class 1 IM with the R1 mesh, the flame-retardant weave in Trevira CS offered in five colours; the approval is declared for that mesh, so the line is quoted with the mesh code beside the chair. The seat is a separate matter: there the class is the one of the fabric chosen, and several in the programme carry class 1 IM as fabrics in their own right. A specification that needs the approval therefore names the R1 for the back and a class 1 IM covering for the seat, and quotes nothing about the chair alone.
Vaghi lists a safety anti-return system on the mechanism, next to the synchronised movement and the tension adjustment. What it governs is the release: when the lock is let go while someone is still leaning back, the backrest does not spring forward. It is on both mechanisms of the programme, the weight-activated one and the one with tension adjustment, and it is not an option to be ordered; it comes with the chair, whichever letter is written for the mechanism.
Yes, in category D: the fabric Vaghi calls 24/7+, a crêpe for use around the clock, blended from 50 % polyamide, 33 % wool, 10 % FR viscose and 7 % viscose, 609 g, rated at 400,000 Martindale cycles, the highest figure among the fabrics listed for Assia EV. The chair under it does not change: the fabric is a seat choice, ordered by its category, and the mesh on the back is chosen separately, so a 24/7+ seat can sit under any of the three weaves.
The whole backrest. Vaghi describes it as a medium mesh back that is height-adjustable and reclining: the frame itself rises and lowers on the chair and tilts with the synchronised movement, while the grey lumbar bar makes its own travel inside it, read off its position indicator. Two separate adjustments, listed as two separate points on the Vaghi drawing, number 2 for the backrest and number 6 for the lumbar, and both come on every one of the three builds.
Vaghi codes an Assia EV as a short grammar: a pair of letters for the series, one for the mechanism, one for the build, one for the base and castors, then the mesh and the seat. Five steps to write it.
An Assia EV line opens with the series, two letters. EB puts the chair in the white series, with plastics, armrests and castors in white; EN puts it in the black one, the same parts in black. Where the lumbar support should adjust in depth as well as height, the pair is written 2B or 2N in their place, and the rest of the code is unaffected by that swap.
Next comes the mechanism, as a single letter. E marks the weight-activated synchro, the one with nothing to set; S the synchro whose tension is adjusted by hand to the person sitting; T the synchro that adds a seat-depth adjustment, written in place of S when the seat should move forward and back. The anti-return safety goes with all three.
The fourth letter is the build. K stands for the armchair with headrest and armrests, I for the armchair with armrests, 5 for the chair without any. Armrests on K and I adjust in height; for arms that also move in depth, with a swivelling top, Z or V replaces the letter; for height, width and depth together, with the same top, Y or T.
Fifth is the base. D is polyamide, white on the white series and black on the black; B is painted aluminium in white, L painted aluminium in black, X polished aluminium on either series. Castors in rubber, for hard flooring, come as standard; where the floor is textile the hard castor is ordered by changing that same letter, D to C, B to W, L to I, X to J.
After the chair come the coverings. The mesh takes a 13 in front of the weave and its colour: RE for the standard polyester weave, R1 for the flame-retardant weave in Trevira CS, RS for the three-dimensional one. The seat is named by its category letter, A to F, or declared as the customer's own fabric, for which Vaghi wants its characteristics stated before assessing feasibility and quantity.
