Abstract
Abstract A chair for children has a base frame from whose sides two parallel lateral struts rise with a rearward slant, these struts being engaged by a pair of sleeves that are indexable at different levels thereon. The sleeves are rigid with respective lugs on which a seat-supporting bail is pivotable about a horizontal axis, the bail being immobilizable in a selected angular position by a handwheel through the intermediary of a jaw clutch. The base frame, normally resting on the floor, can also be suspended from a headpost of a bed.
