IKEA MARKUS Office Chair Review: The Guarantee Outlasts the Adjustment List

Check the seat measurements before anything else

IKEA publishes a seat width of 53 cm, a seat depth of 47 cm, and a seat height that runs from 46 to 57 cm. Overall height spans 129 to 140 cm, so the headrest reaches well above most desks. The chair as a whole is 62 cm across and 60 cm deep, and no other seat adjustment appears in the published list.

Because the seat pan does not slide and the lumbar pad is not described as movable, those dimensions are the fit. Long thighs will run past 47 cm of seat depth, and a shorter sitter meets the lowest seat setting at 46 cm with a desk that may now sit too high. The UK listing offers the chair in Vissle dark grey and Vissle light grey at the same £159 and the same 110 kg test load; the UK listing shows no larger-seat MARKUS, so it offers a bigger frame no step up. The numbers are the whole of what IKEA publishes about fit.

Two things adjust, three things support, and the listing keeps them apart

The features block on the page reads: lumbar support, armrests, manual tilt tension, synchronised tilt, a tilt lock with three positions, adjustable seat height, and a safety function whose wording is that the castors lock when the chair is not in use. Only the seat height and the tilt tension carry the word adjust. Lumbar support and the armrests are described by what they do for the back and shoulders, with no range of motion given for either.

For a sitter who sets a chair once and leaves it, the tilt tension and the three-position lock cover the daily needs, and the locking castors are a sensible detail around children or on a hard floor. For a sitter who alternates between typing and reading and pushes the arms out of the way, the absence of any stated armrest adjustment is the deciding line. IKEA UK's guarantee page names MARKUS and covers its moving parts and frame, and the brochure names it too, but neither lists an armrest or back-rest adjustment mechanism, so they settle nothing about what moves.

The materials are plain, and the guarantee is the argument for them

The frame is steel with an epoxy/polyester powder coating, the star base is aluminium, the seat frame is layer-glued wood veneer, and the seat foam is polyurethane at 35 kg per cubic metre. The back fabric is 100% polyester, and the cover fabric is 73% polyester (at least 90 percent of it recycled), 20% modacrylic and 7% cotton. IKEA lists the cover as fixed, marks the chair suitable for business use, and names it in a brochure of office chairs tested to EN 1335 and ANSI/BIFMA X5.1.

A fixed cover means a stain or a worn seat edge stays with the chair, and the armrest pads are polypropylene with synthetic rubber, a wear surface with no replacement part shown on the listing. IKEA does run a free spare parts service, which is the place to ask. Against those wear points stands a ten-year guarantee, longer than most people keep a desk chair, though which parts it reaches is not settled: the guarantee page names the moving parts and frame, and the brochure lists no parts at all.

The brochure sets the terms: ten years from the date of purchase, with the receipt required, covering "defects in material, workmanship, and function". It excludes "normal wear and tear, cuts or scratches, or damage caused by impacts or accidents", and a chair placed outdoors, in prolonged direct sunlight or in a humid room. IKEA says the guarantee sits alongside your statutory rights.

One box, 22 kilograms, and a build before the first sit

The chair ships as a single package measuring 59 by 22 by 97 cm and weighing 21.95 kg. IKEA links an assembly instruction PDF on the listing but publishes no assembly time or tool list. On 2026-10-16 the page data showed home delivery in stock and click and collect available. For a lone chair the delivery table's £10 band (15 to 75 kg, standard, 5 to 30 days) looks like the relevant one, since the box is under the 25 kg threshold; IKEA quotes the exact fee and date at checkout.

That weight changes who should buy. A buyer near a store with a car and a second pair of hands pays £159 and an afternoon. A buyer relying on delivery should price the fee at checkout first. IKEA UK takes back most unopened products within 365 days with a full refund to the original payment method. A chair that has been opened or assembled is taken back within 365 days with a receipt, but the refund goes to a refund card, and signs of use beyond testing it are not eligible. Returning a 22 kg chair is its own errand.

Skip it if you tune a chair by the arms or the lumbar

Skip the MARKUS if your routine depends on armrests that drop out of the way, a lumbar pad you can raise or lower, or a seat pan you can slide forward; not one of those appears on the listing, and a chair that fits by luck fits nobody for long. Step past it as well if you sit near or above the 110 kg test load, since the published figure is a test condition and nothing more.

Buy it if your seated measurements land inside the published seat band, you want a headrest and a mesh back, and a ten-year guarantee at £159 matters more to you than a long menu of levers. The recommendation is conditional on those measurements and on a fit you confirm against your own body before paying.
