Ask three institutions what university lecture furniture should feel like and you get three answers. A technical campus wants a surface that takes abuse and a wet cloth. A faculty of law wants wood. An auditorium used for convocations wants something softer. On the E4000 those are not three products: they are three executions of the same three parts.

The first is plywood faced with HPL on both sides. The second is beech or oak plywood under a clear polyurethane coating, described by the manufacturer as anti-glare, anti-slip and scratch resistant. The third is upholstered over an inner plywood support, in fabric or faux leather, with padding certified CertiPUR®. Three parts, nine ways to specify them.

What does not change is the load path. Whatever surface is chosen, the ergonomic backrest keeps the same profile, the mechanisms keep the same travel and the structure keeps the same parts: the specification is written once and holds for all three.

For a campus that is the practical gain: several halls can be finished differently while the installation method and the spare-parts list stay single. Geometry is free in the same way, in line or along a curve, over stepped levels or a sloping floor, and the bench comes as front, middle or end row.

When it is the right choice

  • Campus specifying several halls at once and wanting one structure under different surfaces.
  • Hall with steps or a sloping floor already built.
  • Tender asking for low formaldehyde wood components.

When another solution serves you better

  • Where the tiers are not yet built: the E4000 has no platform of its own, while Lamm's Blade System brings one.

FAQ

What are the three executions of the E4000 seat and backrest?

Plywood faced with HPL on both sides; beech or oak plywood with a clear polyurethane coating that the manufacturer describes as anti-glare, anti-slip and scratch resistant; or upholstered over an inner plywood support in fabric or faux leather. The three share the same parts and the same structure.

Does the structure change if the surface changes?

No. Beams, uprights, feet, the tip-up mechanisms and the writing tops stay the same. That is what lets a campus run one hall in oak and another in fabric while holding a single installation method and one spare-parts list.

What centre distance does the system need?

It is adjustable from a minimum of 51 cm, rising to 55 cm where armrests are fitted. Module width is 48 cm and the first stretch of the row 24,5 cm, or 29,5 cm with armrests.

Is there a place for bags under the seat?

A storage basket is available as an accessory, with a frame in 2 mm steel coated in semi-matt silver or semi-matt black RAL 9005. It is ordered per seat or for the complete row, not supplied by default.

Are the wooden parts low emission?

The manufacturer declares the wood components as low formaldehyde emission, and the padding used in the upholstered execution as CertiPUR® certified. Both are declarations of the producer and are quoted as published.

Combining the E4000 front row with conference armchairs

The manufacturer allows the first rank to be built differently. These steps cover how to set that up in a hall.

Decide what the first rank is for

Where the front of the hall seats a panel, a convocation party or visiting faculty, the E4000 front bench can give way to conference armchairs. The decision applies to that rank alone; from the second row back the system continues.

Check the starting dimensions

The E4000 works from a centre distance of 51 cm with a first stretch of 24,5 cm. Those two figures are what the chosen armchairs have to line up with, so compare them before anything is ordered.

Keep the panel where it is still needed

Front-row panels are single and vertical, high enough to cover the lower bar. Where an armchair takes the place of the bench the panel falls away; where the bench stays, keep it so the beam is not left in view.

Keep the metalwork to two tones

Steel parts across the hall come in semi-matt silver or semi-matt black RAL 9005, with foot covers in silver or black technopolymer. Bring the armchair base into one of those two tones rather than adding a third.

Get the mixed rank drawn and confirmed

A mixed first rank should be drawn and confirmed with the manufacturer before the order is placed. It is the one place in the hall where two systems meet, and it is checked on the working drawing.
