And so, old seats are being removed this week and new ones, being fabricated by Ducharme Seating in the Montréal borough of Saint-Leonard, will arrive shortly. The old ones were installed in the mid-1990s and had become lumpy, Kimmel officials said. The new models are of a slightly larger width — 18 to 22 inches, as opposed to 16¾ to 20 inches — but will use velvet of the same deep-red color as the old ones.
