The invention relates to an adjustable underframe for an armchair or chair seat, which is intended to facilitate sitting down in and rising from an armchair or chair mounted rigidly thereon. The underframe is characterized by a slab (5), frame or the like which bears the armchair or the chair seat and which can, in the intended front part of the armchair edge or chair edge, be raised and pivoted in the vertical direction on a base part by means of two pivotably mounted arms (12, 13) on either side of the latter, one (13) being pivotably mounted on the other (12), and also a drive arrangement (10) for raising and pivoting.
