Comfort Back Care Chair HM502



Prevent and Manage Back Pain

The Comfort Back Care Chair HM502 is different than the other specialist back care chairs in the HM range as the backrest is specially designed to wrap around the back. The cushioning on the backrest supports the whole back and the result is an extremely comfortable and soft support for the back. When sitting for long hours the spine and back need good support to maintain good posture reduce the pressure on the back muscles and spine. This is particularly important for office workers who are sitting for long hours.

Note: We stock Black. For any colour other than the standard black there is an additional charge of 150,00 + vat as these are non stock items. The lead time of 8-10 weeks. Please contact for more information.

Best chair for bad backs for executives

Our body needs movement and variaiton and if we listen to our body it is constantly giving us signals it needs to change positions. That's why so many office workers move into slumped positions.

Static working positions results in muslce fatigue and strain that can lead to back pain and neck pain. The Comfort Back Care Chair HM502 offers complete support in every seating position.

The nature of office based work is people are sitting on their office chairs for very long periods. Too long for our body. Our body isn't designed for sedentary work.  We need to move to keep our bodies healthy.

Modern research in ergonomics proves the importance of postural variation. It is important to avoid sitting still for long periods and to change your position regularly.Excellent Back Support when sitting

The HM502 allows you to take opportunities to vary your seated position while maintaining good posture, thus reducing strain on the back muscles and the spine.

It allows you to lean back, sit upright and stretch out your body also.

The unique "kneeling chair" position that is possible with the forward 
tilt, allows the user to open the hip and pelvis angle and sit without support but with your spine in a neutral position activating the core muscles.

Gives great support and for prolonged sedentary work

Excellent Lumbar support while stretched out
The Comfort Back Care Chair HM502 gives you unrestricted movement when sitting, which means you can fluidly move be sitting upright, s
tretched out, in an active sitting position or reclining without touching a button

This is the perfect chair for people who's work requires to spend a lot of time at the desk and are conscious of their health.

The Comfort Back Care Chair HM502 will ensure the user is comfortable and happy in their office chair. It is a long term solution to preventing and managing back pain. Back pain is one of the main reason for absenteeism and effectively managing it will reduce absenteeism significantly. A comfortable and healthy workforce are a happy workforce. If an employee can focus on their work and not be distracted by tension, discomfort or pain, than their performance will increase also.

The additional comfort with the Comfort Back Care Chair HM502 makes it a great solution for busy executives who sit for long hours, as well as back pain sufferers. The stylish design and top of class performance makes it the perfect executive chair for management teams.

I have a Herman Miller Aeron chair, which I used love thrown in the corner. This chair is just a different level
Rose W. on 10/02/2017 Different level of comfort
I've worked in some of the biggest companies in Ireland and I've tried the best egonomics chairs that they had. I even had a bespoke chair built for me and this is by far the best support and most comfort I've ever experienced when working. It is the ability to change position and recline so fluidly that makes it the best back care chair for me.
Alexandra B. on 10/03/2017 This is the best chair I've ever sat on
I'd just like to thank Frank for all his help in selecting the chair. He really took the time to understand my requirement and it was great to be able to test them. Of course, I have to have went for the most expensive one in the shop. It's been the best money I've ever spent because I'm able to do full days again without suffering at the end of it. I think when Frank came out and did the set and gave advice on layout etc was hugely helpful. Great chair and even better service!
Daithi G. on 29/09/2017 It's very expensive but definitely worth it
The way the chairs stays supporting you when you recline, really takes the pressure of my back. I can't fault the chair, I just wish it was a little cheaper :)
Tomas H. on 30/01/2017 Fantastic chair, love the recline
It's unreal!!
Killian M. on 18/08/2017 Best ergonomic chair I've ever sat on
My physio recommended it and it really is the best chair for back pain I've ever had. I've spent a lot of money on my previous ones and while they were good, they weren't comparable with this chair!
Hugo B. on 13/11/2016 My third chair for back pain and this is the best
