    If you are using your chair on a hard surface flooring like wood, wood laminate or natural stone surface, you may want to consider optional soft wheel casters. Optional soft wheel casters reduce the chance of marring or leaving marks on your hard surface flooring. These soft casters are inserted into the base at time of assembly as opposed to the standard, or included, casters.

      We bought 27 of these chairs for our meeting room. They were easy to put together once you do the first one. it took about 15 minutes to put together each chair - you need a power screwdriver. A few of the chairs had issues with the backs being really loose and we needed to manipulate the plastic piece on the end of the back support that inserts into the bottom of the chair and tighten the bolt REALLY tight. The look good and are OK for comfort for an hour or so but probably not good for all day sitting. Also, the chairs say they are intended for individuals weighing 250lbs or less but they are really better suited for smaller people - wouldn't be very comfortable for anyone over 190-200 lbs (they might be a little narrow). Oh, and you CANNOT lean back in these chairs AT ALL . The chairs look nice once they are together but not as high quality as some chairs I have bought for around $100. So. in my opinion, a good chair for occasional use or short duration, easy assembly, good value under *****. If you can afford to spend the extra $50 bucks, get a nicer chair.

      I'd recommend this chair to anyone who wants a pretty satisfactory desk chair, and really likes to assemble furniture. I had to hire someone to help me put it together..I don't have the tools, so that was my only choice. Now that it's a full fledged chair, I lke the size, the appearance, and the mobility. Guess I hate assembling.

      The chair was fairly easy to put together and it is comfortable. If I have any complaint at all, it would be that the seat is a little lower than I expected and would prefer. My understanding is there is just the one setting.

    • What I needed, no more

      The chair is sturdy, the seat cushioning is not great, it's a bit of a hard sit. However, I am not sitting at my desk for more than an hour or so. I wouldn't recommend it if you were using it all day. I was satisfied with the purchase, given my needs.

      This chair is exactly what I wanted. It's sturdy, comfortable and it fits my small space perfectly. The package it arrived in was rather battered but the chair itself was in good condition, and I put it together by myself in about 15 minutes. I did end up getting a floor mat because this chair doesn't roll very well on carpet, but I suspect that would be true of most chairs.

      I've had this chair for a year now and it is still awesome! My back doesn't hurt at all when I sit in the chair for hours. My daughter likes to twirl in it. LOL.
