Klass Height Adjustable Desk: The Specifier’s Guide.

Klass Height Adjustable Desk: The Specifier’s Guide.

Written by OLG Office · Published 29 October 2026

What’s new for Klass.

A round leg option

Klass now comes with a 70mm round leg alongside the 80 x 50mm rectangular leg. It shares the same lift, height range and load rating, so the choice is purely about the look. Round legs soften a floor and suit collaborative, hospitality-style and education spaces; rectangular legs line up with straight joinery and screens for a crisp, architectural feel.

Quick assembly with the Klick-n-Rise frame

The Klass Klick-n-Rise frame assembles in under 5 minutes. With pre-fitted bolts and an integrated handset, Klass simplifies installation without compromising performance. Against a comparable frame that takes 15 minutes to install, that saves around 10 minutes per frame, over 30 hours on a 200-desk project.

A quieter 41dB motor

Klass now runs on a motor rated at 41dB, down from 46dB on the previous motor. Decibels work on a log scale, so a 5dB drop cuts the sound energy by around two thirds, a difference you can hear across an open plan floor. For reference, a typical open plan office sits at around 45 to 55dB of general background noise and normal conversation at around 60dB, so at 41dB the lift sits under the noise of the room around it.

What is Klass.

Klass is OLG Office’s Australian designed electric sit-stand desking system for commercial fitouts. It pairs a slim leg, in 80 x 50mm rectangular or 70mm round, with a German-engineered dual-motor lift, and is built to take a full workstation load of 140kg. It comes as single desks, double-sided workstations and 90° corner workstations, with matching fixed-height frames for areas that don’t need sit-stand.

The idea behind Klass is simple: a height-adjustable desk that looks lighter than most, goes together in minutes, adapts its cabling to any screen or space, runs quietly enough for open plan, and carries the certifications a commercial project needs to sign off.

Configurations.

• Single-sided desk (SSD): a standalone sit-stand desk for individual workpoints, home-base desks or executive offices.
• Double-sided workstation (DSD): two back-to-back desks sharing a central spine for screens and cabling. Suited to open-plan neighbourhoods.
• 90° workstation: an 1800 x 1800mm corner layout for roles that need more surface, such as reception, finance or design teams.
• Fixed height: the same Klass frame at a fixed 715mm, so sit-stand and fixed desks look the same across a floor.
• Frame only: for projects supplying their own worktops, in any width from 1200 to 2200mm.

How Klass performs.

A quieter motor

The German-engineered motor runs at 41dB (the previous motor was 46dB), below the general background noise of a typical open plan office. In a floor of 100 desks, motor noise is the difference between people using sit-stand and people leaving it at one height.

Fast, and safe

Klass rises at 38mm per second. If it meets an obstruction, such as a chair arm or a pedestal, the anti-collision system stops it and reverses slightly. Anti-tilt protects the frame if the load is uneven.

Memory that gets used

The 3-point memory handset stores sitting and standing heights, shows the height on an LCD readout and can be set with upper and lower limits. The controller is built into the handset, so there is no separate control box to mount.

Slim, but not light-duty

Both leg profiles are slimmer than the typical sit-stand leg, yet each desk carries 140kg evenly distributed: enough for multiple monitors, a desktop PC and a monitor arm. Every leg is test-cycled three times before it is packed.

Quick to install

Under 5 minutes per Klick-n-Rise frame, with no loose screws, means less time on site and fewer parts to manage: over 30 hours saved on a 200-desk project, against a comparable 15-minute frame install.

Cabling that adjusts to the job

The adjustable cable tray changes position without compromising the frame’s structure, so one Klass frame suits every screen type, power setup and space on the floor.

Certifications and warranty.

AFRDI Blue Tick

Klass is certified by Furntech-AFRDI to AS/NZS 4442:2018, the Australian and New Zealand standard for office desks, workstations and tables. It is certified for general safety, strength and durability, and stability (certificate 18533/1). The certification covers the whole Klass range, including the new round leg.

Global GreenTag GreenRate Level C

Klass is independently certified by Global GreenTag (certificate 2981), with no toxicity issues of concern in the Health and Ecotoxicity assessment. GreenTag lists it as contributing to the Sustainable Products credit in Green Star Interiors v1.3.

PFAS free

Klass is free of PFAS (per- and polyfluoroalkyl substances, often called ‘forever chemicals’), which supports projects with healthy-materials or chemicals-of-concern requirements.

Supplied by an ISO-certified business

OLG Office holds ISO 9001 quality management and ISO 14001 environmental management certification.

10-year warranty

Klass is backed by OLG’s 10-year commercial warranty. Certificates are available at olgoffice.com/certificates.

Screens and cable management.

Klass works with OLG’s own screen systems, so workstations can be planned for privacy, acoustics or brand colour:

• AcoustIQ: acoustic PET screens, 1330mm finished height, in straight and curved wrap options, including dual colour screens with a different colour on each face.
• Edge25: a 25mm-thick fabric screen with fine aluminium edging and a pinnable core, 1300mm finished height on the workstation.

Underneath, an adjustable cable tray supports shared or separated cabling, with punch-outs and plates that suit CMS, Elsafe and other power providers. The tray adjusts without compromising the frame’s structure, so it can be set on site to suit any screen type, from AcoustIQ and Edge25 to monitor arms and above-desk power, and any space, from single desks to 90° workstations. Installers get full flexibility on the day, rather than locking the cabling layout in at order. Add-ons include GPO and data plates, a cable basket, cable bridge, cable cobra, above-desk power and a ceiling starter kit.

Where Klass fits.

• Corporate and hybrid offices: shared neighbourhoods where many people use the same desk and quick, memorised height changes matter.
• Government and professional services: projects that need AFRDI certification and sustainability documents in the tender response.
• Green Star projects: GreenTag GreenRate certification supports the sustainable products credit.
• Large rollouts: the Klick-n-Rise frame saves over 30 hours of installer time on a 200-desk project.
• Mixed screens and power: the adjustable cable tray sets up on site for any screen type and power provider, without compromising the frame.
• Awkward floor plates: any width from 1200 to 2200mm, fits between columns and existing joinery without settling for a fixed size.
• Mixed floors: fixed-height Klass frames keep the look consistent where sit-stand isn’t needed.

How to specify Klass.

1. Choose the layout: single, double-sided or 90° workstation.
2. Choose the size: any width from 1200 up to 2200mm, including every size in between, and a depth of 600 to 800mm.
3. Choose sit-stand or fixed height for each zone.
4. Choose the leg: 80 x 50mm rectangular or 70mm round.
5. Choose a screen: Edge25 or AcoustIQ (straight, curved wrap or dual colour).
6. Choose finishes: black, white or custom frame colour; standard or premium worktop.
7. Add power and cabling: adjustable cable tray, GPO and data plates, cable cobra. The tray is set on site to suit the screens and space, so cabling doesn’t need to be locked in at order.
8. Ask your OLG reseller for the spec sheet, CAD and Revit files, renders and the certificate pack.
