After adjustment of the backrest, the integrated iliac crest support is set to the correct position. The chairs are available optionally with closed, functional or multifunctional armrests. All versions feature an aluminium armrest support assembly, adjustable without using tools. The entrada Counterchair enhances the range with a swivel chair, featuring a raised seat, infinitely- variable height-adjustable circular footrest, and glides.
