Abstract: A chair has a seat with a seat shell. A frame for supporting the seat has, on its side facing the seat, a mounting strut running parallel to the plane of the seat shell. An underside of the seat shell if formed with a receiving profile for the mounting strut. The receiving profile has a fastening section extending from a circumferential edge of the seat shell parallel to a plane of the seat shell into the interior of the seat shell and having an access opening at the circumferential edge of the seat shell. A clamping strip is provided for clamping the mounting strut in the fastening section. The clamping strip is slid from the access opening in a direction parallel to a longitudinal direction of the fastening section and is fixed in its end position in the fastening section perpendicular to the plane of the seat shell.

Abstract: This disclosure provides systems, methods, and apparatus related to the determination of ecological processes. In one aspect, a device includes a base and a substrate in contact with a first side of the base. The base defines a stem port. The substrate and the first side of the base define a chamber. The chamber includes a root chamber and a first nutrient chamber. The root chamber and the first nutrient chamber are separated by a first mesh having openings of about 1 micron to 300 microns. The device is operable to house a plant, with roots of the plant being in the root chamber, and a stem of the plant passing through the stem port.

Abstract: A seating furniture includes a seat with a seat surface, a pedestal and a tilt mechanism. The tilt mechanism is disposed between the pedestal and the seat and permits an inclination of the seat surface of the seat relative to the horizontal. In addition, the tilt mechanism has a lower bearing block mounted to the pedestal, and an upper bearing block fixedly connected to the seat. The lower bearing block has a convexly curved lower bearing surface on its upper side facing the upper bearing block, and the upper bearing block has a concavely curved upper bearing surface on its lower side facing the lower bearing block. The lower and upper bearing surfaces have substantially corresponding radii of curvature, so that the upper bearing block can be moved relative to the lower bearing block along the upper bearing surface. A tilt mechanism for seating furniture is also provided.
