Built for the Shift That Never Ends
Most office chairs are built for one person and a working day. A control room chair is never empty: as one operator stands up, the next sits down, at three in the morning as at three in the afternoon, and every one of them is a different size. The RH Secur24 was developed for exactly that. Its tilting mechanism is a robust steel construction with a hardened steel block, built for continuous use rather than an eight-hour day, and the whole chair weighs 30 kg.
It is certified to BS 5459-2, the British standard written specifically for heavy-duty and 24-hour office seating, alongside EN 1335 and GS. In the control tower Flokk photographs it in, it is doing the same job it does in Australian control rooms, monitoring centres and dispatch desks.
Cushions and Support for the Long Haul
Sitting for a twelve-hour shift is a different problem from sitting for an hour. The Secur24's seat and back cushions are extra thick, the seat 11 cm thick, and ergonomically shaped so pressure is spread rather than concentrated. The 65 cm backrest has a large angle of inclination and a lumbar support that adjusts from 18 to 29 cm above the seat, operated from the side of the backrest, so the curve lands where your spine is.
Above it, the headrest adjusts for height and angle and supports the head and neck when you lean back to watch a bank of screens. Flokk recommends it; it is fitted as standard on the chairs we stock.
Controls on Both Sides
Every adjustment lever on the Secur24 is duplicated: seat height, seat depth, back angle and tilt are all reachable from the left and the right, so a left-handed operator is not fumbling under the seat for a lever on the wrong side at the end of a shift. The sliding seat sets depth for users of different heights, and the padded armrests flip up and away so you can get in and out of a console quickly.
The mechanism gives dynamic seating: the seat follows your position as you move rather than holding you fixed, which matters over hours in front of a screen.
The Details
Five Things That Make It a Secur24 Basic
RH's chair for control rooms and observation workstations, held in our Sydney warehouse in black Trento leather and black Forever fabric, configured as photographed with headrest, padded flip-up armrests and a polished aluminium base.

A Heavy-Duty Mechanism
The tilting mechanism is a robust steel construction with a hardened steel block, developed for continuous use rather than an eight-hour day. The chair weighs 30.2 kg and is certified to EN 1335, GS and BS 5459-2, the British standard for heavy-duty and 24-hour seating.

Extra-Thick Cushions
The seat and back cushions are extra thick and ergonomically shaped so pressure is spread rather than concentrated, the seat 11 cm thick. It is the difference between sitting for an hour and sitting for a twelve-hour shift.

Ergonomic Back, Adjustable Lumbar
The 64.8 cm backrest has a large angle of inclination, 18°, and a lumbar support that adjusts from 18 to 29 cm above the seat from the side of the backrest, so the curve lands where your spine is.

Controls on Both Sides
Seat height, seat depth, back angle and tilt are duplicated on the left and the right, so a left-handed operator is not reaching for a lever on the wrong side. The padded armrests flip up and away to get in and out of a console.

Headrest and 24/7 Upholstery
The headrest adjusts for height and angle and supports the head and neck when you lean back to watch a bank of screens. Flokk covers upholstery under the 24/7 guarantee term only where it is an RH-approved 24/7 fabric.

The figures here are Flokk's own, from the RH Secur24 factsheet, measured to EN 1335-1 and rounded to the nearest half-centimetre. Compared with a heavy-duty task chair such as the RH Mereo or RH Logic, the difference is the whole build: the Secur24 is guaranteed for control room 24/7 use, the others for normal use up to nine hours a day. Chair Dinkum is the exclusive Australian distributor for the Flokk group, so a guarantee claim is assessed and handled by us in Sydney — terms are on our warranty page.
RH Secur24: Flokk's user guide
This Model
This listing is the RH Secur24 Basic, held in our Sydney warehouse in two upholsteries: black Trento leather, and black Forever fabric. The chairs we hold are configured as photographed: headrest, padded flip-up armrests, polished aluminium base and castors for hard floors; soft-floor castors, a coat hanger, a weapon recess in the back cushion, holster protection and hygienic or protective covers are options. Other RH-approved 24/7 fabrics and leathers are available to order.
Chair Dinkum is the exclusive Australian distributor for the Flokk group, and Flokk's 5-year control room 24/7 guarantee on this chair is assessed and handled by us in Sydney. Full terms are on our warranty page.
Why We Stock It
We stock the Secur24 because it is the chair we can put into a control room and not hear about again. Flokk built it for observation and monitoring work where the seat is never empty, and the operators who use ours are in mining and utilities control rooms, security monitoring, dispatch and transport control. It is heavy, it is plain, and it is built to be adjusted by whoever sits down next.
Arrange to sit in one at our Pyrmont showroom alongside the RH Mereo and the HÅG Capisco. If you are fitting out a whole room, call 02 9640 0642 and we will quote the project, including armrest, castor and cover options, and confirm lead times on the upholstery you want.

Dimensions
Dimensions are Flokk's published figures from the RH Secur24 factsheet (measured to EN 1335-1), rounded to the nearest half-centimetre. The 234 kg figure is the maximum static load published in BMA's Secur24 literature (BMA merged into RH on 1 January 2025); it is a static load test, not a certified maximum user weight, and Flokk's current factsheet publishes no user weight limit for the chair. RH's general published maximum user weight is 150 kg. If a rated capacity is a mandatory tender requirement, call 02 9640 0642 and we will confirm the current certified figure with Flokk before you submit. Guarantee terms are on our warranty page.
Frequently Asked Questions
A normal task chair is designed and guaranteed for one person, up to about nine hours a day. A control room chair is occupied around the clock by a succession of people of different sizes, so everything is heavier: the Secur24 has a steel-framed, hardened-steel tilting mechanism developed for continuous use, an 11 cm thick seat cushion, a 30 kg build and upholstery chosen for wear and cleaning. It is certified to BS 5459-2, the British standard written specifically for heavy-duty and 24-hour seating, as well as EN 1335 and GS. Flokk's guarantee for it is its control room 24/7 term rather than the standard nine-hours-a-day term.
Both are the same chair. Trento is a black leather: easy to wipe down, and the choice where the chair is shared across shifts and cleaned often. Forever is a black fabric: warmer to sit on over a long shift and less prone to showing scuffs. Flokk's guarantee covers upholstery under the 24/7 term only where it is an RH-approved 24/7 fabric, so if the upholstery guarantee matters for your tender, call 02 9640 0642 and we will confirm the status of each before you order.
Flokk provides a 5-year guarantee on RH chairs approved for control room 24/7 use, which includes the Secur24; upholstery is covered under that term only where it is an RH-approved 24/7 fabric. The 10-year RH term you may see quoted elsewhere is the standard-use term (up to 9 hours a day, users up to 150 kg), not the control room term. Chair Dinkum is the exclusive Australian distributor for the Flokk group, so a claim is assessed and handled by us in Sydney, not sent offshore. Full terms are on our warranty page, and your Australian Consumer Law rights apply in addition.
BMA's Secur24 literature publishes a maximum static load of 234 kg for the heavy-duty mechanism. That is a static load test, not a certified maximum user weight, and Flokk's current RH Secur24 factsheet publishes no user weight limit; RH's general published maximum user weight is 150 kg. If a rated capacity is a mandatory requirement in your tender, call 02 9640 0642 and we will confirm the current certified figure with Flokk in writing before you submit.
Control rooms in process, mining and utilities; security and CCTV monitoring; police, emergency and transport dispatch; air traffic and port control; observation posts in hospitals and correctional facilities; and gatehouses at bridges and locks. Anywhere a seat is occupied through the night by whoever is on shift. Options such as a weapon recess in the back cushion and protective covers exist for uniformed users; ask us about them.
Yes. Call 02 9640 0642 first and we will have a Secur24 ready for you at our Pyrmont showroom, Shop 1, 209 Harris Street, in the upholstery you want, alongside the rest of the RH range. If you are specifying a whole control room, we quote projects directly and can talk you through armrest, castor and headrest options. Our control room chair range sets the Secur24 alongside the other 24/7 chairs we stock.
