DeskOne Office Chair Range Explained: Apex, Ergo Pro, Pulse and More

Desk One's office chairs sort into four broad groups, and the honest summary is that each group answers a different question. The entry Ergo task chairs (Ergo Flex v2, Flex V3, Comfort, Klassic) cover certified basics; the mid-tier mesh trio (Pulse, Lite, Vortex) adds locking recline, headrests and better armrests; the flagship recline family (Ergo Pro, Plus, Supreme, and the Apex Ergo) is built for all-day sitting with footrests and wide recline ranges; and the premium performance line (Prime, Grid, Ultra Flex, Ultra) brings 4D armrests and seat-depth adjustment. A leather executive range and two specialists round things out. This guide maps every model so you can place yourself in the range on facts rather than product names.

What the whole range shares

Before the differences: every chair here carries a 1-year warranty and a 7-day return for faulty items including return freight, and ships from Desk One's own Willawong (Brisbane) warehouse — where there is also a showroom — rather than being drop-shipped. Across the store, Desk One holds a 4.8-star average over 90+ verified Judge.me reviews. Silent-running castors are standard across nearly the entire line, and the ergonomic models are overwhelmingly mesh-backed for airflow. Pricing is tiered exactly as the families suggest: the Ergo task chairs are the affordable entry point, the mesh trio sits in the mid range, and the flagship and performance lines occupy the premium end.

Entry tier: the Ergo task chairs

The Ergo Flex v2 is the range's certified bargain: full BIFMA certification, a patented butterfly-shaped lumbar insert, flip-up armrests and a 135kg rating on a 39–49cm seat height. The Ergo Flex V3 keeps the same seat range and rating and adds a fixed headrest. The Ergo Comfort (also BIFMA certified) swaps mesh seating for a shaped high-resilience cushion with fixed armrests and an 8-degree back tilt, and the Ergo Klassic is the minimalist of the four, with a mesh back, rectangular lumbar cushion and recline to 120 degrees. What this tier omits — deliberately — is multi-position locking recline, adjustable lumbar and anything beyond basic armrests. Our budget chairs guide covers how to shop this tier well.

Mid tier: Pulse, Lite and Vortex

The mesh trio is where adjustability starts compounding. The Ergo Pulse pairs a nylon mesh back and elastic mesh seat with a three-position tilt lock and an SGS-certified Class-3 gas lift. The Ergo Lite brings full BIFMA certification, an adjustable headrest, 2D armrests and a three-position locking recline. The Ergo Vortex is the adjustability pick of the three: a 4D headrest, 4D armrests and adjustable lumbar support — a combination that does not reappear until the premium tier. All three run the same PP engineering frame family and stay resolutely black-and-grey office mesh.

Flagship tier: the recline family and the Apex

The Ergo Pro is the anchor: BIFMA certified, 150kg rated, with a spine-mirroring arc backrest, U-shaped adjustable headrest, 3D armrests, a 103–130° recline and an optional add-on footrest. The Ergo Plus (also 150kg, BIFMA) takes recline furthest — 95–152° with dual lumbar pads that keep contact through the whole arc, linked armrests that move with the backrest, and a built-in footrest. The Ergo Supreme tops the Ergo series with a built-in footrest, 112–133° four-position recline, synchronised 3D aluminium armrests and a lumbar system adjustable across up to 20cm, on the tallest seat range in the line-up (43.5–59cm).

The Apex Ergo stands slightly apart as the most advanced chair Desk One makes: it adds the two adjustments the Ergo Pro lacks — sliding seat depth (42–44.5cm) and a height-adjustable backrest (61–68cm) — on a 48–56cm seat height, 150kg rating and 70cm aluminium base, with the Apex Ergo+ variant adding a retractable 17cm under-seat footrest. If you are tall, this family is where to look first; our tall users guide compares them on exactly that axis.

Premium performance: Prime, Grid, Ultra Flex and Ultra

The performance line trades footrests for precision. All four have 4D armrests and sliding seat-depth adjustment. The Prime runs an aluminium-alloy wire-controlled chassis with a 103–130° recline, three-position tilt lock and a 120kg rating. The Grid is the balanced mid-point of the four, while the Ultra Flex and Ultra introduce an adaptive TPEE backrest — a flexible polymer frame that moves with the body rather than holding one shape — with the Ultra adding a high-elastic mesh headrest at the top of the line. The Grid, Ultra Flex and Ultra specify BIFMA-certified gas lifts and wheels.

The specialists and the leather executive range

Two models sit outside the tiers. The Flow is a minimalist one-piece mesh chair aimed at lighter, shorter sitting sessions, and the Star builds wireless-controlled massage and heating into an ergonomic mesh frame with a 120kg rating. Then there is the leather executive range: the Essential, LuxCraft and Comfort cover the accessible end in PU leather high-backs; the Executive (independent back-and-seat movement), Luxura Elite and Prestige (both with 105–125° tilt and integrated headrests) form the middle; and the Dynamic tops the line with built-in massage, a 150° recline and a USB port. Our executive chairs guide covers that side of the catalogue in depth.

Where a cell shows a dash, the listing does not state that figure — worth knowing rather than guessing.

How to choose across the range

A practical shortcut: if your sitting is moderate and your budget firm, an entry Ergo task chair — ideally a BIFMA-certified one — covers the fundamentals. If you want locking recline and a headrest without reaching the premium tier, the Vortex is the strongest spec of the mid trio. If you sit all day and value recline and footrests, the flagship family is built for exactly that, with the Apex Ergo as the pick when fit matters most — taller users especially. And if precision adjustment is the priority, the performance line's 4D armrests and seat-depth sliders are the range's ceiling. Whichever tier fits, the underlying decision is the same one our features guide unpacks: pay for the adjustments your body will actually use. You can browse the full line-ups directly: budget chairs, ergonomic chairs and executive chairs.

Frequently Asked Questions

How is the Desk One office chair range organised?
Four broad groups: entry Ergo task chairs (Ergo Flex v2, Ergo Flex V3, Ergo Comfort, Ergo Klassic), a mid-tier mesh trio (Ergo Pulse, Ergo Lite, Ergo Vortex), the flagship recline family (Ergo Pro, Ergo Plus, Ergo Supreme plus the Apex Ergo), and a premium performance line (Prime, Grid, Ultra Flex, Ultra), alongside a leather executive range and two specialists, the Flow and the Star.

What is the difference between the Ergo Pro and the Apex Ergo?
Both are 150kg-rated flagships with 3D armrests, U-shaped headrests and a 103-130 degree recline. The Apex Ergo adds the two adjustments the Ergo Pro lacks: sliding seat depth (42-44.5cm) and a height-adjustable backrest (61-68cm), which is why Desk One positions it as the most advanced chair in the line-up.

Which Desk One chairs have a built-in footrest?
The Ergo Plus and Ergo Supreme have footrests built in. The Ergo Pro offers an optional add-on footrest, and the Apex Ergo+ variant adds a retractable under-seat footrest that extends up to 17cm.

Which models are BIFMA certified?
The Ergo Flex v2, Ergo Comfort, Ergo Lite, Ergo Pro and Ergo Plus carry full-chair BIFMA certification per their listings. The Grid, Ultra Flex and Ultra specify BIFMA-certified components (gas lift and wheels) rather than full-chair certification.

What do the leather executive chairs offer instead of mesh?
PU leather high-back designs with integrated headrests and simpler mechanisms: the Essential, LuxCraft and Comfort cover the accessible end, the Executive, Luxura Elite and Prestige add refinements like independent back-seat movement and 105-125 degree tilt, and the Dynamic tops the line with built-in massage and a 150 degree recline.

What warranty and returns apply across the chair range?
Every chair carries a 1-year warranty, with a 7-day return for faulty items that includes return freight. Chairs ship from Desk One's own Willawong (Brisbane) warehouse, which also has a showroom, and the store holds a 4.8-star average across 90+ verified Judge.me reviews.
