About a week ago I received my Hinomi H1 Pro V2 Standard in black. I am 5'6". It was easy to put together. Things that I liked right away were all the ways I can adjust the chair. I can lock it in any position I want, upright, partially leaning back or all the way back with a few stops in between. I also like the leg supports and the ability to extend the leg supports without flipping them over. This let's me sit with legs bent and my heals resting on the extended leg support. I liked the head support more than I thought I would. Also the heal grips on the legs let's me put my feet on the base of the chair and not the floor. The lumbar support was a little uncomfortable at the start, but mostly because my last chair didn't have any lumbar support. It is also configurable and not is one of my more favorite features.
I did read a few reviews about the weak arm rests. They are great when you are sitting down, but I did find them less than desirable when I used them to adjusting my position sitting in the chair or getting out of the chair. The arm stiffness are very related to your back being against the back of the chair.
Over all the chairs is very comfortable, and much of that is because it is so adjustable. I really questioned if I should spend this much on a chair. It was hard to make the decision to do it, but I am really glad I did. This chair is a huge upgrade from my mid-range Staples chair.
If you are on the fence about getting this chair do it. I waited too long. It is a great, sturdy chair that can almost always be adjusted to meet your needs.
I would definately buy it again.
