The Blidrum Family
About the Blidrum.
Blidrum in a medium-back proportion
The medium-back Blidrum is designed for open-plan desks and meeting rooms where a full 1.2 m executive back would visually dominate a shared space. The single-piece moulded shell, the hand-stitched full-grain leather, the cast aluminium detailing: all identical to the high-back version. Only the proportion changes — a 490 mm backrest that clears the eyeline at a standard desk and lets the room breathe.
Integrated moulding, hand-stitched leather
The backrest and seat pan are formed as one continuous shell using integrated moulding technology. Removing the assembly seam that most executive chairs still show, the shell carries its own stress in a continuous flow — so the chair keeps its shape year after year. Full-grain first-layer cowhide, with visible fine pores and its natural coating retained, drapes the surface in precise, even hand stitching.
Arched sponge, dynamic split-back support
Under the leather sits Blidrum’s arched sponge — a raised support point that presses back into the lumbar curve rather than a concave cushion that collapses into it. When you shift, the high-elastic material fills the gap; when you settle, it wraps the cushion tight to spine and buttocks with a cloud-like density. The dynamic split-back distributes weight across two supported zones and adjusts to your posture in real time.
Adjustable, quietly
Seat height adjusts from 445 to 505 mm across a 60 mm travel. The 14° recline runs from 103° to 117° with an in-situ lock at every position. Multi-function aluminium mechanism, steel gas-lift, and PU casters that roll silently on hard floor sit under a single control lever, embedded flush in the seat cushion so the underside stays as clean as the upper surface.
Built to stay in service
Aluminium alloy armrests, a 340 mm five-star aluminium base — available in black powder coat or polished finish — and a PP35 + PP28 moulded shell carry Blidrum through years of daily use. Backed by a five-year quality assurance covering manufacturing quality. Assembly required.
Finish options
Full-grain leather in Black, Dark Blue, Brown, Coffee and Dark Gray, or woven fabric in Black, Blue, Grey and Pink. Every combination available with a black powder-coated or polished aluminium base.
Everything for the executive day.
