Info Overview

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.

FAQ Blidrum

Questions about this product.

All FAQs
What’s the difference between the two base finishes?

Both share the same 340 mm five-star aluminium construction and load rating. Black Powder Coated gives a matte black finish that recedes into the room; Polished gives a mirror-bright aluminium that catches light and reads more formal. The choice is purely visual — pick to match your desk and floor rather than for performance.

Can I choose leather or fabric?

Yes. Five full-grain leather colourways (Black, Dark Blue, Brown, Coffee, Dark Gray) and three fabric options (Grey, Blue, Pink). Leather uses selected first-layer cowhide with the natural coating retained; fabrics are woven for daily executive use.

How does the tilt lock work?

Pull the control rod on the right of the mechanism to unlock the recline. Set your angle anywhere in the 14° range (103°–117°) and release the rod — the chair holds in place at that exact position (in-situ lock) rather than snapping to a preset.

What is the warranty?

Blidrum carries a 5-year quality assurance for manufacturing defects when used, stored and assembled correctly. Damage from misuse, sharp-object contact, improper storage or normal wear on upholstery is not covered. Full T&Cs apply.

Is assembly required?

Yes. Blidrum ships flat-packed. Assembly is straightforward — attach the five-star base and gas-lift to the pre-built shell. Full instructions and tools are included in the box.
