TRALT Ergonomic Office Chair (Black)

Sizing and fit

This is the part to get right. The seat is 20 in wide and 17.3 in deep, with a seat height of 18.5–21.3 in, and TRALT states a fit range of about 5 ft 5 in to 6 ft 2 in. A comparison site lists the same seat at 19.7 in wide with a 17.7–21.7 in height range. One reviewer who reports 30 days of 10-hour days in this listing measures the seat pan at roughly 17 in front-to-back and says that above about 6 ft 1 in the front edge presses into the backs of the knees and reduces lower-leg circulation over hours; he narrows the recommendation to 5 ft 4 in to 6 ft 1 in. Overall dimensions are not trustworthy: a third-party spec record says 21.7 × 25.7 × 40 in while a video description says 46.9–49.2 in, and no TRALT page publishes the numbers. The mesh back and seat breathe well, the seat is flat so an owner can add a cushion, and the tall back suits taller users in the owner thread.

What owners report

In the November 2025 r/OfficeChairs thread, owners describe the lumbar support as comfortable and not overdone, the seat as flat all over so third-party cushions fit, and the backrest as tall enough for a tall user. The same reviewer reports silent non-marking casters, a lockable tilt, and lumbar adjustment in both height and depth, which he calls uncommon at this price; a separate aggregator says the lumbar is depth-adjustable only, and TRALT itself says only “adjustable”, so the adjustment axes stay unconfirmed.

Beyond the fit limit, the recurring cautions are mechanical. The recline knob needs a 2–3 day break-in, the armrest height-lock ratchet strips after six or more months, and the backrest-to-seat assembly step leaves a permanent wobble if it is rushed. Owners also report squeaking after 12–14 hours of daily use and, in a small number of cases, hydraulic failures within the first month. These are signals from a small evidence base, not defect rates, and no failure or return rate for this model was found.

Assembly, warranty, parts and running costs

Assembly is required and the seller says all tools are included and the job takes about 15 minutes; that is a seller estimate, not an independent timing. The chair has no electronics, no power draw and no consumables, so running cost is $0 a year on paper. The wear items are the casters, seat foam, mesh, armrest mechanisms and gas lift.

Warranty is unresolved: TRALT’s own site advertises a lifetime warranty with replacement of necessary parts and an affiliate video repeats that, while a third-party review of the sibling model states two years. No written terms, exclusions or claim process were found for this model, so confirm the terms in writing before checkout. Repairability is a weak point: no TRALT parts catalogue or replacement gas lift, caster set, armrest or mechanism was found, so a sinking gas lift, dead casters or a stripped armrest means sourcing third-party parts elsewhere, and no verified prices for those were found.

Is it worth it?

The TRALT-US storefront listed the exact-title black variant at $149.99 in October 2026, and the Consumer Reports shop module listed a TRALT chair at $113.99 in August 2026. At or below about $115 the chair’s core proposition holds: 330 lb capacity, a metal base, adjustable lumbar and flip-up arms in a breathable mesh shell. From $116 to $150 it is fair, because the same shopping list includes chairs with more adjustability and longer warranties, and above $150 it weakens. At that point the Sihoo M18 is the named alternative, with 2D arms, a cushioned W-shaped seat, a 126° recline and a 3-year warranty; the trade-off is that a specialist review found its seat too firm, its tilt lock prone to sticking and about 90% of its parts plastic. The Marsail adds 3D arms and 1.18 in of lumbar depth adjustment with a 275–280 lb capacity, and the COLAMY Atlas offers an inflatable lumbar airbag. Fit is the deciding factor: the chair has credible owner support from about 5 ft 4 in to 6 ft 1 in, and above 6 ft 1 in the short seat pan works against it.

Which model this is

This page covers the black TRALT mesh office chair with adjustable lumbar support, sold under ASIN B0CQD3K8PJ. A third-party spec aggregator maps it to the chassis lead YX001-2, but TRALT does not publish that mapping and the same page’s “armless” field is wrong, so treat the code as a lead. Don’t merge it with TRALT’s YX001-1 chairs, the leather variants or the newer models, which use different backs, armrests and features. The exact listing’s published attributes show no headrest, though the brand’s YX001-2 text and one review mention one, so confirm from the photos before ordering.
