    Adjustable, roomy cushions for customized comfort

    • Adjustable backrest helps you find your comfort zone.  The adjustable seat back depth feature allows you to move the back of your seat forwards or backwards. For optimal positioning, adjust until the front of the seat is just behind your calves for maximum comfort and support. The backs of your thighs should rest fully supported against the seat.

    • 1-touch seat-height adjustment for proper posture.  Quickly and easily raise or lower your chair with the pneumatic lever until your feet rest flat on the floor for proper ergonomic positioning.
    • Recommended for moderate use 3-6 hours per day.  Chair is built to keep you comfortably seated from 3-5 hours per day.

    Rated 4 out of 5�by Gret chair, but has some assembly issues. I had read several reviews of this chair before purchasing, and really wish some of them had been a bit more specific in their mention of "easy to put together once you got the hardware removed from the bottom of the cushion". Since not everyone mentioned any difficulties with assembly, I had assumed that the people who made that comment were those who were not used to putting things together, etc. But in fact, it doesn't matter how much experience you have assembling office furniture, if you get one of the "duds," this chair takes over an hour to assemble. The reason it takes so long is not because it is difficult to understand the directions--on the contrary. The instruction diagrams are very detailed and easy to understand, even for someone who prefers word instructions. The problem is that the assembly hardware comes already inserted into the bottom of the cushion for some reason. I guess it makes it less likely that anything will go missing during the packing process, but for customers, it makes the assembly process a nightmare. If memory serves, I believe there are 14 screws total on the bottom (although for this model, you do not need to take out the two sets of three screws each on the sides, as those are for models with arms). Of those 14 screws, we only needed to remove 8 to put my chair together. It took us an hour to remove those 8 screws. The first 3 came out easily with a normal Phillips head screwdriver. The other 5 were torqued in there so deeply at the factory that it took two very strong people an hour to remove them. There is no way to put the chair together without removing all 8 of them, so it's not like you can just choose to ignore the ones that won't come out and put it together with the remaining 5 or something like that. After an hour, when we finally had all the screws out, the chair actually went together very easily. There was a bit of confusion between steps 3 and 4, because you put it together backwards from what you would expect by just looking at it. But be sure to follow the instructions, and you'll be fine. An average strength, beginner "handy gal" could easily put this chair together by herself if 1) she does not end up with a "dud" model that had the screws torqued in too deeply at the factory or 2) she has a very strong and patient person to help her remove the screws if she did get a dud. If you end up with a non-dud model, you will be able to put it together in around 10 minutes, from the time you open the box until the time the chair is ready to use. As for the chair itself, it seems to be very comfortable so far. Nice firm cushion, decent back give (doesn't really recline, but has enough give to allow a decent seated stretch). And thus far, it is supporting my significantly higher than rated weight. The description of this chair online no where mentions a weight limit, but the packaging states that it is rated only up to 250 pounds. I weigh a LOT more than that, and it seems to be supporting me just fine. The pneumatic lift isn't strong enough to raise the chair with me sitting in it, but once I set the level, it is holding just fine. Of course, I just put the chair together today, so we'll see if it continues supporting me over time. Even better, the seat is actually wide enough for my extra large posterior. And since it doesn't have arms, there is no discomfort to my hips like with many chairs. Basically, if you're looking for a comfortable chair for someone between 250-300 pounds, without having to shell out an extra $150.00 for a big and tall model, and you are willing to be patient with the assembly process, look no further than this chair.
