I currently have one of these: http://www.ikea.com/gb/en/catalog/products/20103101 It is very comfortable. Also like the headrest. Unfortunately it isn't very well constructed - after a year the tilt mechanism was having issues and the armrests are peeling. That being said, I could buy five of these for one Aeron...

 

I don't think anything from IKEA is designed to last. I think Aerons are guaranteed for twelve years.
