Input:
Question: How is the coil seating? does the padding feel like it's made for heavy duty use (e.g., 8-10 hours of use a day)?
Document: Descent Ergo design. Not much tilt, even when loosened. Looks good in the ad, feels like the price. Coil Springs seat a benefit.
By the way US patent numbers have exceeded 8.7 million. A patent with a number 666,436 must be from 1890s. Obviously average Joe Blow does not know this. I have 23 US patents and 24 pending.Eco leather, on the other hand is defined as recycled leather with a polyurethane coating and fabric backing. It only has 20% leather in it. In other words, Made in China.After using for about 48 hours, I find the chair comfortable and decided to raise the stars to 3.
It's comfortable. I have all wood floors in my office (no rugs) and the wheels just glide so effortlessly over the floor that I actually have to catch myself from wheeling across the room when I sit down!! The lumbar support is perfect for me and the top cushion provides support for my shoulders too, which I like because I am typing on a computer all day. I also like the color which is supposed to be a sort of wine I guess, but actually against the cherry wood in my home office, looks more of a rich cocoa brown than purple.
It does not matter if it is comfortable to sit on it. Go to Costco. They have easier to assemble units.After 2 hours it is assembled. It is not bad in comfort so I was going to raise it to three stars. Then I saw on the box US Patent no D666436. Another attempt to fool the customer. A US patent starts with US and is followed by a number. It never has a letter up front. It can have a letter at the end such as US 8,776,345(B1).
I bought this chair through Amazon with out trying it out --I have had many desk chairs of various qualities and prices for over 40 years. So I was pleasantly suprised when I found that this was one of the best chairs I have had. What makes it so is quality of construction, the eco-leather (actually &#34;bonded&#34; leather) which looks and feels fine, and especially the seat with coil springs (few office chairs have coil springs), a front bolster for under the thighs and good back support.
I am so glad that I decided to take the plunge and purchase this chair. I work from home and spend a lot of time in my chair and let me tell you, it was a 100% improvement over my old office chair, that I didn't realize how bad my old chair had gotten, until I sat in this one. I'm 5 foot 8 inches tall, and a gal who has curves and hips, but there's plenty of wiggle room and nice cushion in the seat for the butt and thigh area.
First  of all Eco leather means polyurethane f aux  leather. Don't expect "Corinthian leather. Pure synthetic. It took me literally 20 minutes to put it together. The arms are a different story. It has been almost two hours . I put together the left one in 45 minutes but the right one does noit align. My time is valuable. I have assembled many things at home; I am an engineer. I am so tired now I gave myself a break. I am going to try one more time and if I cannot assemble, I will take itb apart and return it.
It was relatively easy to assemble except for attaching the arms -- it was difficult to find the sockets to screw the bolts in to. I would not let this discourage anyone. The price was excellent for this product and I recommend it highly.
I was concerned that the back might be too short because no clear dimensions were provided. However, it fits very well my 5'9&#34; frame.
I challenged myself to put this chair together myself before my husband came home, and it was indeed a challenge. But having said that, it came together very well, and looks quite snazzy at his desk. For the price, it is great. Good swivel, hydraulic lift still works (several months later), and a nice shade of brown.
Answer: I'm 6 ft, 205 lbs, and yes the chair is very comfortable. The coil helps, BUT the main thing to consider is that most manufacturer's use "lower end"  foams,{softer} when they build cushions, they want it to be soft when someone first sits in it. After a peroid of time the foam will fail, crush, {makes you feel like you are sitting on a board}. Then you can  take it to a "quality" upholstery shop and get them to replace the foam with a better quality, more dense foam. That will last you forever.  I have not changed the foam on this chair yet , but have done it to others. {Maybe just repair the foam in your old chair if you like it..................     mike
