168. Where the space between tables is very restricted the chairs should be fastened to the floor, so that there can be no blocking of gangways. One plan is that adopted at the Mitchell Library, Glasgow, North Library, Fulham, and elsewhere, of having revolving arm-chairs mounted on pedestals secured to the floor. These have the one great disadvantage of being non-adjustable. Readers cannot pull them a little forward or push them back, and thus such fixed chairs have the defect of all fixed things—they cannot be moved to suit varying conditions. Another form for a crowded situation is a small strong chair of good design anchored to the floor by means of a stout cord ([Fig. 54]). Each chair has a stout staple screwed under the seat in the centre, and a similar staple is screwed into the floor at a suitable distance from the table front, and corresponding in situation with the staple in the chair seat when placed in position. Lengths of stout window cord are then cut and provided with swivel hooks at either end, which are fastened to the staples on the floor and on the seat, allowing a sufficient length of cord to admit of a fair amount of play and movement when anchored. On granolithic or other cement or concrete floors, fixed chairs cannot be used readily.
This kind of anchorage allows of a chair being moved backwards, forwards or sideways, and readers can get to and from their seats without trouble. Arm-chairs are not recommended for this style of fastening.
All kinds of chairs should be shod with rubber or leather pads to deaden the noise of movement on the floor. There are several varieties of such pads to be obtained from furnishing firms.
