Quick Answer: Costco sells office chairs in two distinct tiers — $99.99-$139.99 mesh task chairs (True Innovations, Bayside Furnishings, TrueWellness) backed by a 1-year warranty, and $289.99-$299.99 big & tall executive chairs (La-Z-Boy Calix, Henredon Adrano) backed by 5-to-10-year warranties. Every chair requires an active Costco membership ($65/year Gold Star, per Costco’s current pricing), and the mesh tier’s 1-year coverage is shorter than even the budget ergonomic brands already ranked on this site — while the big & tall tier’s warranty is genuinely competitive, just on a different kind of chair.
Costco’s office chairs get recommended constantly in “cheap ergonomic chair” threads because the $99.99 price tag is real and the chair in the photo looks like it belongs in the $250 bracket. What rarely gets mentioned is that Costco’s chair lineup isn’t one product with one warranty — it’s two tiers with a 10x spread in coverage — and that the $65 membership fee applies either way. This guide puts both tiers next to the chairs this site already ranks: the Sihoo Doro C300, the Branch Ergonomic Chair, and the Costco standing desks covered in our companion guide.

The Metrex IV is the chair most shoppers mean when they say “Costco office chair” — a real mesh back, real adjustability, and a price that beats almost everything on Amazon at a glance. The catch is the same one that showed up on Costco’s standing desks: one year of warranty coverage, against the 3-year flat term Sihoo puts on its entire lineup, including chairs at a similar price point.
The warranty split most shoppers miss
Costco’s chair lineup isn’t one warranty story — it’s two. The mesh task chairs (Bayside Furnishings, True Innovations, TrueWellness) all sit at 1 year, per each brand’s own published warranty documentation. But the big & tall executive chairs are a different product built by a different calculus: the La-Z-Boy Calix carries a genuine 10-year limited warranty, and the Henredon Adrano — manufactured by True Innovations under the Henredon name — carries 5 years on the frame and mechanism, though its upholstery and foam cushioning fall back to the same 1-year exclusion window the cheaper chairs use outright.
| Chair | Price | Warranty | Membership required? |
|---|---|---|---|
| Bayside Furnishings Metrex IV | $99.99 | 1 yr | Yes ($65/yr) |
| Sihoo M18 | $169.99 | 3 yr | No |
| Sihoo Doro C300 | $279.99 | 3 yr | No |
| La-Z-Boy Calix Big & Tall | $289.99 | 10 yr | Yes ($65/yr) |
| Branch Ergonomic Chair Pro | $499 | 7 yr | No |
Line the two groups up and a pattern holds at both price points: the mesh tier loses badly on warranty-per-dollar against Sihoo’s flat 3-year term, which costs nothing extra to access. The executive tier flips that — the La-Z-Boy Calix’s 10-year warranty is genuinely stronger than Branch’s 7-year term on its Pro chair, at a lower price. The honest takeaway isn’t “Costco chairs are bad,” it’s that the two tiers need to be evaluated completely separately, and the $65-130/year membership fee applies to both regardless of which one wins on paper.
Return policy: a real safety net, not a warranty substitute
As with Costco’s standing desks, office chairs fall under the unlimited satisfaction guarantee Costco applies to furniture, rather than the 90-day cap on electronics, per Costco’s published return policy. A chair that arrives with a torn seam or just doesn’t fit the body can go back for a full refund with no deadline. That’s a genuine advantage over a typical Amazon return window. It doesn’t extend a 1-year warranty, though — a return requires getting the chair back to a warehouse (or arranging a pickup) while membership is still active, which doesn’t help if a gas lift or recline mechanism fails in year two on a chair whose manufacturer coverage already ran out.
Who a Costco office chair actually makes sense for
Already a member, and want the cheapest real mesh chair available. If the $65-130 membership is sunk cost regardless, the Metrex IV at $99.99 undercuts almost anything comparable on Amazon — you’re weighing a 1-year warranty against Sihoo’s 3-year term, not the membership fee on top of it.
Need a big & tall chair and want to see it in a warehouse first. The La-Z-Boy Calix’s 10-year warranty and 350 lb capacity are a strong combination that Amazon-native brands like Branch and Sihoo don’t directly match at the same price, and Costco’s in-warehouse stock lets buyers sit in it before paying.
Don’t want a recurring membership fee just for a chair. If $65-130 a year isn’t already part of the household budget, the math rarely favors Costco’s mesh tier: the Sihoo Doro C300 matches its price and triples its warranty with zero membership required.
Bottom line
A Costco office chair splits into two real products: a $99.99-$139.99 mesh task-chair tier with a short 1-year warranty, and a $289.99-$299.99 big & tall executive tier with a genuinely strong 5-to-10-year warranty. Both require the same $65-130/year membership. For most buyers who aren’t already Costco members, the Sihoo Doro C300 beats the mesh tier on warranty at a similar price with no membership fee, and the Branch Ergonomic Chair Pro is the closest Amazon-available equivalent to the La-Z-Boy Calix’s territory.

For the other major retailer-vein pick, see our Walmart office chair guide — no membership fee required, but a flat 1-year warranty at every price point, unlike Costco’s La-Z-Boy Calix tier.
