Trade terms for professionals and design studios

Walk through a theater after the last show and you can tell which seats were designed to close on their own. L213, developed by Lamm's in-house research and development office for theaters, convention venues and classrooms, tips its seat up by gravity, with a counterweight: when the person stands, the seat follows, and the row reads as a line of closed backs the moment the house empties.

The manufacturer's technical sheet is that plain about it, and the plainness is the point. There is nothing to reset, nothing to adjust row by row before the next session, and a tipped-up seat leaves 13 inches of free passage with the inclined side or 14 1/8 inches with the straight side when rows are set 35 3/8 inches apart. For a venue that turns over an audience several times a day, the seat that closes itself is the one the staff never thinks about.

Around that seat, L213 is a conventional chair in the best sense: plywood cores in the seat and back, full-height sides in either an inclined or a straight profile, dressed in fabric or leather or veneered in oak and beech, and a stamped sheet-steel foot bolted to the floor. La Mercanti specifies it as auditorium seating for halls that run back-to-back events and cannot afford a row left half open.

Convention centers and lecture halls get the same chair with different accessories: a tablet stowed in the side, a seatback table, a wider side for longer sessions and, where the project demands it, the Floor Technology that Lamm offers to sink every row beneath the floor. Gravity does the closing; everything else is a choice.

FAQ

What keeps the anchor foot of L213 from showing wear where cleaning carts hit it?

An epoxy powder coating the manufacturer describes as scratchproof and anti-corrosion, applied over the stamped sheet steel of the foot. It comes in semi-matte black RAL 9005, semi-matte silver, embossed bronze and embossed graphite, so the foot can match the hall instead of just surviving it.

Can rows of L213 be moved out of a hall and moved back in?

Yes, for chairs with floor-fixed feet in straight rows: Lamm offers an accessory system that makes the chairs removable and rolls them on casters when they are not in use. The hall can host a banquet or an exhibition and reseat itself afterward without losing the row plan.

How does a patron find seat 14 in row G?

With two separate accessories: a row identification element visible from the aisle and a seat number on each chair. La Mercanti fixes the sequence against the hall plan before installation, because the numbering has to follow the way people actually enter, not the order in which the rows go in.

What is the T200 that appears in the L213 drawings?

A tip-up writing table on its own single base, made for seats that have no backrest in front of them, typically the first row. With the chair, the overall footprint is 41 1/8 inches for the inclined side and 40 1/8 inches for the straight side.

Is the back of the L213 backrest wood or fabric?

Either. Behind the backrest you can specify exposed plywood, oak or beech, or a fully upholstered surface matching the seat. Wood gives the row behind a hard, wipeable face; upholstery makes the whole row soft, which theaters tend to prefer.

Installing and checking the fold-away tablets in L213 sides

The sequence for fitting the writing tablets housed in the sides of L213 chairs, from the opening direction to the test every tablet gets before the first class.

Mark which seats get a tablet

The tablet of L213 lives inside the load-bearing side, so the decision is made per seat and per side: on the hall plan, mark each position that takes one and note whether that chair has an inclined or a straight side.

Set the opening direction

Each tablet swings out of the side toward the person seated; its anti-panic movement lets it give way in the direction of the exit. Check that the direction matches the aisle on that end of the row before the sides are fixed.

Fit the tablet and its joint

The top is black stratified HPL on a die-cast aluminum joint that folds the tablet flush into the side. Once mounted, the top sits 25 5/8 inches above the floor with the inclined side and 26 3/8 inches with the straight one.

Open and close every one

Before the hall is handed over, each tablet is opened, loaded by hand and folded back into the side; a tablet that catches or stays proud of the side is adjusted then, not after the first lecture.

Record the positions

The final list of tablet seats, by row and number, stays with the hall documentation; La Mercanti keeps a copy so that any later addition uses the same orientation and the same side type.
