I have a real leather Hero and also work from home, it's a truly great office chair in my opinion, I looked at designer office chairs but they're usually thin mesh or fabric material, and some don't even have headrests, they don't seem to offer as much chair for the money despite offering arguably superior ergonomics. Though the Hero is still great in that regard if you're bigger or taller and like a firm chair, it also has inbuilt adjustable lumbar support which many designer chairs don't. If you can swing for the leather it's worth it as a legitimate work from home office chair you can claim your VAT back on, it should also pay for itself quickly, the PU ones definitely seem good too though and also durable.
Here's a quote from another topic with some of my thoughts:
"I got a real leather Noblechairs Hero around a month back and I've done a few 50-60 hour working weeks in it, plus gaming, not 24 hour but likely as much as anyone has sat in the same chair in a working environment. I just checked out a few of those so called 24 hour rated chairs and I can say without doubt the Hero is better than many of them. Some of those "24 hour" rated ones don't even have adjustable armrests and they have curved ones at that.
Some complain the Hero is too hard as it's built very durably with firm, though still comfortable padding, but if you're even slightly larger or taller it's a really great chair for working long hours in my opinion. I think it's actually improved my posture."
