A lecture hall is reset several times a day, and in many rooms the reset is left to whoever happens to be passing. On ST12-13 by Lamm, designed by Orlandini Design, it is built into the arm. Each of the two seats on a bench is carried by a pivoting arm in die-cast aluminium, and that arm pivots under an automatic spring return through an excursion of 64°.

Release it and it comes back, so a row that students have left falls into order without anyone walking it. The seat swivels a full 360° and is pulled back by a calibrated automatic return; according to Lamm, that rotation allows people in neighbouring rows to share one table. That is why the system sits between university furniture and collaborative workspace furniture. The two movements are separate: the arm swings, the seat swivels.

Arm finishes are black RAL 9005 or silver, both semi-matt, or graphite with an embossed texture, and they may differ from the finish of the central steel structure. Two seats are offered, HL³ on ST12 and New Modulamm on ST13. Units are joined two seats at a time, in rows that run straight or curve, set on flat ground, an incline or steps, and benches can also face each other as an island seated from two sides.

On an Indian campus where one hall serves several batches in a day, a room that puts itself back in order is the detail that counts between sessions.

When it is the right choice

  • University rooms used for both teaching and syndicate work.
  • Layouts where the writing surface must stay put while the seat swivels.
  • Plywood or upholstered finishes across the two seat types.

When another solution serves you better

  • Where capacity comes first and seats should fold up along one long run, Lamm's E5000 allows spacing from 51 cm.

FAQ

Can the HL³ seat be only partly upholstered?

Yes. On ST12 the HL³ comes as bare plywood, in beech or oak, with full padding, or with padding on part of the shell only. On ST13 the New Modulamm seat comes in pressed and curved plywood or fully upholstered. In every case the padding is CertiPUR® certified.

How many fabric collections are offered for each version?

Ten for ST12: Inca, King, Trevi, Maya, Silvertex, Extrema Au, Ultra, Luna CS, Revive 1 and Remix 2. Six for ST13: Inca, King, Trevi, Maya, Silvertex and Extrema Au. The wider choice therefore sits on the HL³ seat.

Has the system received any design awards?

Yes, twice over. ST12 holds a Best of Competition title, Educational Spaces Innovation Awards 2015, New Orleans, USA. Its HL³ seat, the work of Lucci and Orlandini, collected a 2010 Good Design award (Chicago Athenaeum) plus a NeoCon 2010 Silver Award (The Best of NeoCon).

Does the installation have to be fixed to the floor?

The central structure is fixed through a steel sheet floor anchor plate. For installations that are not fastened to the floor, Lamm offers an inter-row bar as an accessory, which is useful where the flooring should not be drilled.

Which tests does Lamm declare for ST12-13?

According to Lamm, ST12-13 is tested to European standards, though the numbers of the individual standards are not listed. Any specific standards a project or tender calls for are confirmed project by project against the manufacturer's documentation.

Switching an ST12-13 layout from ST12 to ST13 on a finished plan

The bench is identical in both versions, the seat is not. These are the figures that move on the drawing when the seat changes.

Keep the bench width

On ST12-13 the bench is the same in both versions: 120 cm wide for two seats, with the writing top at 75 cm and the seat at 44 cm from the floor. None of these change.

Allow for the deeper ST13 footprint

Bench and seat need 60 cm front to back on ST12, 66 cm on ST13. Every row on the plan grows by that difference.

Recalculate the row pitch

Rows sit 95 cm apart with ST12 and 100 cm with ST13. On steps the tables break this down as 30 + 60 + 35 and 30 + 66 + 34, so the step depth has to be checked again.

Lengthen the straight runs

Six seats in a straight line go from 395 to 405 cm, because the end sections grow from 60 to 65 cm on each side. Check that the ends still clear walls and aisles.

Recheck spacing and fabrics

The centre distance between the two seats of a bench moves from 68.5 to 68 cm, and the fabric choice narrows from ten collections to six. Confirm both before the finish schedule is closed.
