ELABEST X100 Ergonomic Mesh Office Chair with Footrest: problems, parts and running costs

Checked: 2026-10-05

Summary

The most-reported fault is the 5D flip-up arm pad: owners say it moves in every direction and has no locking position on top, so it drifts under forearm pressure. The footrest and the folding arms also start stiff, and the mesh seat is firm rather than padded, so many buyers add their own cushion. Money spent after the purchase is close to nothing — the chair is not powered, there are no consumables or subscriptions, and ELABEST sells no spare parts for it anywhere on its own sites. Value depends almost entirely on price: a footrest-equipped X100 at about the $219 one owner saw as a sale price is well specified for the money, while the $349.99 a desk retailer listed in August 2026 buys a chair with no independent test behind it and a base whose material is disputed.

Common problems and fixes

Arm pads drift and have no lock — the clearest owner-reported defect. One owner commenting on this exact listing says the armrest “moves in all directions which is great, but it keeps moving in all directions. There is no locking position of the pad on the top.” [10] There is no frequency data and no confirmed fix in the sources: nothing states whether it is a design omission or an assembly problem, so tightening or bracing the pad hardware is a workaround rather than a repair. Whether the 5-year warranty covers it is not documented; a Newegg listing of this chair defers warranty questions to the seller. [1]
Mesh seat is firm, not plush — an owner who swapped a cheaper chair for the X100 calls the mesh “very firm” and pairs it with a seat cushion; a review spec table lists the seat as cotton over mesh with no cushion. [11][8] Expect to add your own cushion. This is a comfort complaint, not a defect, so warranty handling is unlikely. [1]
Footrest extension is stiff — review sites describe the 18 in extendable footrest as stiff and as taking practice to extend fully. [3][4] The workaround is to work it through its travel a few times before you settle in. No warranty position is documented.
Flip-up arms are stiff out of the box — reported alongside the footrest in the same accounts. [4] They loosen with use; nothing in the sources describes a warranty claim for it.
Lumbar adjuster sits behind the backrest — the 3D synchro-tilt controls are behind the seat back and awkward to reach while sitting. [3] Set the lumbar depth, height and 15° rotation while leaning forward or standing, then lock it. No owner reports a mechanism failure, and warranty handling is undocumented.
Base material is disputed, and a nylon base is a durability risk — every retail and review spec table describes a nylon base, while the brand’s own X100 page says “heavy-duty aluminum base” and elsewhere “heavy-duty aluminum alloy”. [1][2] No observed base failure exists in the sources; it is a caution, not a reported fault. If you are near the stated 300 lb limit, the same review site advises preferring a metal base because stainless bases outlive nylon ones. [3]
Orders can be cancelled for stock — one buyer’s X100 order was cancelled by the retailer for being out of stock after about a week. [9] That is a fulfilment risk rather than a quality fault. Ask the seller to confirm stock before ordering a chair weeks ahead, and keep the written 5-year warranty card that ships with it, since a third-party seller’s terms may be shorter. [1]
Some X100 listings ship without the footrest — one reviewed X100 variant is listed with no footrest included, even though the same publisher wrote a separate piece built around how the footrest changes comfort. [8][2] Check that the listing you buy states the 18 in extendable footrest before you order.

Parts and consumables

EL392 Black Tilt Mechanism (part number EL392) — sold by a third-party parts seller as a direct replacement for the X100; it is the metal box under the seat that controls tilt, the lock and the height lever, and the listing says a swap takes about 20 minutes. [13] No price was captured for it in the sources, so no store or date can be given. No owner in the sources reports replacing one; it is a fix for a failed mechanism, not a scheduled service item.
No official ELABEST spares for this chair — none of ELABEST’s three domains carries a parts channel for the X100, and no base, gas lift, caster, footrest or arm pad is offered for it in any source read. [2][6][12] So a failed component outside the tilt mechanism has no known replacement route, and damage to the arm pad cannot be ordered out even though the pads are the most-reported fault. [10]
Seat cushion — the practical add-on rather than a spare. One owner pairs the firm mesh with a cushion [11], but inclusion is contradictory across sources and ELABEST sells no cushion for the X100; no price or retailer is recorded. [8]
No consumables — this chair takes no filters, pods, batteries or fluid, and no service subscription exists for it.

Yearly running cost

Effectively $0 a year after the purchase, apart from occasional component replacement. The X100 is a non-powered chair with no wattage, voltage or electrical specification, so there is no electricity cost, and no source describes any consumable, cartridge or subscription tied to it. The only recurring spend anyone could plan for is a spare part, and the one spare that exists — the third-party EL392 tilt mechanism — carries no published price, so no annual figure can be computed from the evidence. Care is a wipe-clean. [13][8]

When it is a good buy

Near $219 — the sale price one buyer reported for a footrest-equipped X100, on a chair listed at a $350 list price. [9] At this level the combination of an 18 in footrest, a 3D synchro-tilt lumbar, 5D flip-up arms, a 3D headrest, a 3-stage recline to 135°, a 300 lb rating and a 5-year warranty is hard to match in this class. [1]
Around $250–300 — defensible but thin. You are approaching the tier where chairs with published independent durability testing start to appear, and the X100 has none. [3]
At the $349.99 All About Desks listed in August 2026 — weak. Its only remaining edge is the footrest and the feature count. [7]
Below that, re-check the listing — one AI-written page claims the chair comes in under $170, but that page omits the footrest and calls the armrests 4D, so treat any X100 at that level as a different variant and confirm the 18 in footrest is in the box. [5][1]
Better choice: a chair from a brand with published instrumented testing — the right pick once you are spending $300 or more, especially above 250 lb or if the shipped base turns out to be nylon. No test of the X100 exists on any of the major review labs, and the sites that rank it first share one template and one seller-derived star figure, so they are not a second opinion. [3][4][6][12]
Better choice: ELABEST Executive Office Chair with Footrest, or the ELABEST C57 — worth checking if you want to stay on one brand’s warranty and support line. They are separate products from the X100, and no source gives their dimensions, base material or retailer price, so compare feature lists rather than assuming they are the same chair. [2][6]
